Function

Product Overview

The Thermo Scientific SOLA II sulfur online analyzer combines proven
detection technology, easy-to-use, menu-driven software, and advanced
diagnostics to offer unsurpassed flexibility and reliability. The instrument
offers field programmable ranges, high sensitivity, total sulfur measurement,
fast response time, linearity through all ranges, and low consumables.

Major components of the SOLA II include a sample injection valve, carrier gas
flow control system, mixing chamber, pyrolyzer, optional dryer, and a pulsed
ultraviolet fluorescence (PUVF) detector. Unlike the original SOLA instrument,
the PUVF is not a subassembly. The SOLA II is a single assembly with one
software program and one user interface.

The sample injection valve periodically transfers a small amount of sample
(approximately 1.0 µL) into an air carrier gas. The air/sample mixture passes
through the mixing chamber to ensure complete mixing and then flows to the
pyrolyzer. The pyrolyzer combusts all sample components to SO2, CO2, and
H2O at approximately 1100°C (2012°F). The optional dryer (application
dependent) removes water from the sample that is produced during
combustion. The PUVF detector accurately measures the amount of SO2
produced during combustion of the sample.

An appropriate sample conditioning system is mandatory for proper
functioning. The sample conditioning system should:

λ Regulate sample pressure and temperature.

λ Provide filtration to at least a 0.5-micron particle size. Staged filtration is

recommended (e.g. going from 10 micron to 5 micron to 0.5 micron). The

final filter should contain a hydrophobic element to remove undissolved

water.

λ Ensure that a representative sample is transported to the analyzer in the

desired time.

λ Maintain the sample in a single phase.

Product Overview

Total Sulfur

Measurement

Total Sulfur Measurement

Note Liquid samples with high vapor temperatures such as naphthas and

gasolines will require sample backpressure regulation +0 25–35 psig. σ

λ Remove undissolved water.

Sample should be delivered to the sample conditioning system using a sample
probe. The sample probe should be designed and fabricated so that sample is
extracted from near the center of the process pipe, preventing the
unnecessary introduction of pipe scale and other particulate that tend to
accumulate along the process pipe walls.

Figure 2–1. Functional block diagram

Total sulfur measurement is based upon the precise measurement of the SO2
concentration produced from a wide variety of compounds containing sulfur,
such as H2S, COS, methyl mercaptan, benzothiophenes, dibenzothiophenes,
sulfides, disulfides, and thiols. Consider the measurement of a sample of
diesel, gasoline, or another common petroleum fraction such as naphtha for
liquid phase samples. For liquid phase samples, the analyzer periodically
injects a very small quantity of sample (1.0 µL) of the petroleum fraction into
a hot oven (110°C to 220°C / 230°F to 428°F) where it is vaporized and mixed
with air. Analysis of gas phase samples requires sample sizes of 0.1 to 1.0 cm3.
After thoroughly mixing with air, the sample enters the pyrolyzer, where all
components of the sample are combusted at 1100°C (2012°F) to CO2, H2O, or
SO2. The quantity of SO2 formed during the combustion process is directly
proportional to the total sulfur content of the petroleum fraction.

The analyzer is equipped with a PUVF detector that accurately measures the
quantity of SO2 formed during the combustion process. The SO2 molecules

2-2 SOLA II User Guide Thermo Fisher Scientific

Product Overview

Total Sulfur Measurement

enter the cell of the PUVF detector where they are exposed to ultraviolet (UV)
light. Absorption of UV light by SO2 molecules results in an excited state of
the SO2 molecules. The excited state SO2 molecules exist at a higher energy
state (due to absorption of energy in the form of UV light) and rapidly relax
to their original energy level or ground state through the emission of light.
This process is called fluorescence. The intensity of the light emitted by SO2
fluorescence is directly proportional to the SO2 concentration. Pulsing the UV
light allows more energy (UV light) to be delivered to the sample, increasing
the fluorescence intensity for a given SO2 concentration. This results in
increased overall sensitivity of the instrument.

At the PUVF detector, it is important to ensure that the measured light is
representative of only the SO2 concentration and not some other species. SO2
molecules emit light through fluorescence at a specific wavelength, and the
PUVF detector utilizes bandpass filters to ensure that only light from SO2 is
measured. Once the proper wavelength of light is selected, its intensity is
measure by a photomultiplier tube (PMT). The PMT converts light energy to
electrical energy through manipulation of the photoelectric effect. The
electrical signal generated by the PMT is finally processed by the analyzer
electronics and software to determine and report the concentration of total
sulfur in the liquid petroleum fraction or gas sample.

The analyzer can be configured to report total sulfur in parts per million
(ppm), parts per billion (ppb), or milligrams per liter (mg/L).

λ When using the ppm or ppb units of measure, you can choose to calibrate

the analyzer in terms of ppm (w/w), ppm (v/v), ppm (w/v), ppb (w/w),

ppb (v/v), or ppb (w/v).

λ When using density compensation and the ppm or ppb units are selected,

the display shows ppm/weight or ppb/weight.

Units of concentration calculated on a weight/weight basis are sensitive to
sample density. If the density of the calibration standard is significantly
different from the density of the sample, a density correction should be
applied.

λ If the sample density varies significantly, a density correction is also

necessary when using concentration units of ppm (w/w) or ppb (w/w).

λ If using mg/L, ppm (w/v), ppm (v/v), ppb (w/v), or ppb (v/v), a density

correction is not required.

Thermo Fisher Scientific SOLA II User Guide 2-3

Product Overview

Principle of

Operation

Principle of Operation

The detector is based on the principle that SO2 molecules absorb UV light and
become excited at one wavelength, then decay to a lower energy state
emitting UV light at a different wavelength. Specifically,

The sample inlet bulkhead draws the sample into the analyzer. The sample is
mixed with air and passes through a pyrolyzer furnace that oxidizes the sulfur
molecules in the sample to produce SO2. The sample then flows into the
fluorescence chamber where pulsating UV light excites the SO2 molecules. The
condensing lens focuses the pulsating UV light onto a mirror assembly. The
mirror assembly contains four selective mirrors that reflect only the
wavelengths that excite SO

molecules.

2

As the excited SO

molecules decay to lower energy states, they emit UV light

2

that is proportional to the total sulfur concentration in the sample. The
bandpass filter allows only the wavelengths emitted by the excited SO

2

molecules to reach the PMT, which detects the UV light emission. The photo
detector, located at the back of the fluorescence chamber, continuously
monitors the pulsating UV light source to provide compensation for
fluctuations in the UV light source. The measured SO

concentration

(representing total sulfur in the sample) is processed, displayed on the front
panel display, and sent to the analog outputs.

PUVF Detector

Pyrolyzer

Principle of Operation

The PUVF detector includes and controls the following:

λ UV pulsed light and associated systems

λ Reaction chamber temperature control

λ Digitizing of PMT signal

λ Smoothing of measurement signal using moving average

Measuring total sulfur with the PUVF detection method requires the
conversion of all sulfur compounds in the sample to SO2. This is typically
accomplished with the pyrolyzer, an electrically heated furnace designed by
Thermo Fisher Scientific. The pyrolyzer typically operates at a temperature of
1100°C (2012°F) to oxidize sulfur without need for a catalyst.

Thermo Fisher Scientific SOLA II User Guide 2-5

Product Overview

Dryer

Mixing Chamber

Principle of Operation

The optional Perma Pure dryer removes moisture from the sample prior to its
entry into the PUVF detector. A filter is positioned before the dryer to protect
it from impurities. Dryer tubing consists of multiple small tubes encased in a
large outer tube. Air circulates through the outer tube with sample passing
through the inner tube. Moisture passes from the sample through the tubing
where it is carried to the condensate drain by the airflow in the outer tube.

Figure 2–4. Optional dryer

The mixing chamber mixes the gases and permits the sample to vaporize to a
gaseous state before entering the pyrolyzer.

Product Overview

Injection Valve

Principle of Operation

The injection valve periodically injects precisely measured quantities of the
sample stream into a controlled carrier airflow. An auxiliary airflow is added
to this sample and air mixture. The sample then passes to the mixing chamber
where it vaporizes (if necessary) and is thoroughly mixed with the air. See

Appendix B for rotary injection valve service.

Requirements

Installation

λ Material and power: Consult the specifications for information required

for installation.

λ Operating environment: For optimum reliability and equipment life, we

recommend that the analyzer be installed in a location protected from

extremes in temperature and weather. The analyzer operates best in a

controlled environment. Ambient temperature and purge air must not

exceed the limits listed in the specifications.

λ Mounting requirements: The mounting site must be as close as possible to

the sampling point. The analyzer must be sheltered from extreme weather

conditions. Avoid mounting the analyzer in high vibration areas. Mount

the analyzer in an accessible location.

λ Cable glands used to supply electrical power must be IP40 rated metallic

cable glands.

λ Blanking elements or plugs used shall be in accordance with national

standards.

Caution This product is extremely heavy. Care must be taken at all times to

avoid injury. Never attempt to move this product alone or without the use of
lift gear. When handling the analyzer, ensure that all four corners are
supported.

Installation

Sample Tubing

Preparation

Sample Line Installation

Note Pressure buildup or liquid accumulation in the analyzer vents degrades

performance. Vent lines must be as short as possible and routed in a manner
that prevents accumulation of liquids. σ

There must be no back pressure on the vent or drain lines. All vents must be
referenced to atmospheric pressure. If the analyzer is installed in a pressurized
analyzer shelter, route all vents from the purge controllers and the PUVF
detector to the exterior of the shelter. All sample lines must be as short as
possible. Sample lines must use new 316 stainless steel that has been prepared
as described in the following section “Sample Tubing Preparation.”

The analyzer will produce erratic readings if backpressure is created or varied
by an obstructed or improperly routed vent.

Review the following cautions prior to performing this procedure.

Caution Isopropyl alcohol is extremely flammable, hazardous if breathed, and

dries skin on contact. When using isopropyl alcohol, avoid breathing the
vapors and contact with the skin. Appropriate measures must be taken to
prevent ignition of the isopropyl alcohol vapors. Use isopropyl alcohol only
where there is adequate ventilation and no ignition sources are present. Refer
to a Material Safety Data Sheet (MSDS) for isopropyl alcohol for additional
important information. σ

Caution Acetone is extremely flammable, hazardous if breathed, and dries

skin on contact. When using acetone, avoid breathing the vapors and contact
with the skin. Appropriate measures must be taken to prevent the acetone
vapors from igniting. Use acetone only where there is adequate ventilation and
no ignition sources are present. Refer to a MSDS for acetone for additional
important information. σ

Caution Acetone dissolves many plastics. Use caution to prevent the acetone

from contacting materials that may be marred or damaged. σ

Caution Take necessary precautions to prevent exposure to hazardous

materials when conditioning the sample tubing with sample. σ

Proper preparation of sample tubing prior to installation is very important.
Prepare the sample tubing as follows.

Injection Valve

Failure Alarm

Injection Valve Failure Alarm

Figure 5–3.

Over time, the injection valve begins to wear, resulting in an increased
potential for port-to-port leakage of sample. Such leakage can cause erroneous
measurement and materials buildup in the system. When the analyzer detects
sample leakage through the injection valve, it triggers the Injection Valve
Failure alarm and switches the sample diverter valves to flow air through the
injection valve rather than sample.

Note The Injection Valve Failure alarm must be acknowledged after valve

repair or replacement. σ

If an injection valve begins leaking due to damage or wear, excess sample
begins flowing to the pyrolyzer. This extra load of sample in the pyrolyzer
exceeds the ability to fully combust the materials in the sample. When these
incompletely combusted materials enter the PUVF optical bench, they absorb
UV light.

The PUVF includes a system to monitor and compensate for decreases in the
UV light output as the bulb ages. However, in the case of injection valve
failure, the PUVF system begins rapidly increasing the UV lamp output in an
effort to compensate for the absorption of UV by incompletely combusted
sample products. The user can enter the rate of change that triggers this
alarm. The programmable range is from 1 to 50 V/30 seconds. If the analyzer
detects the programmed rate of change in UV lamp voltage, it triggers the
Injection Valve Failure alarm to protect the system and reduce the
stabilization time for the PUVF bench on system restart.

When the Injection Valve Failure or Chamber Flow alarm activates, a pair of
sample diverter valves switches to flow air through the injection valve instead
of sample. This prevents excess sample and incomplete combustion products
from further contaminating the system. The diverter valves switch air to the
injection valves under the following conditions:

Figure 6–4.

4. The Average Time submenu allows you to set the averaging time. The

average time is a period (1–240 seconds) during which the analyzer takes
SO2 measurements used to determine a moving average of the results. For
example, if you set the averaging time to 10 seconds, the average
concentration of the last 10 seconds is output at each update. If you set
the averaging time to 60 seconds, the average concentration of the last 60
seconds is output at each update. Thus, lower averaging time means faster
response to concentration changes. Longer averaging times are typically
used to smooth output data.

See the figure below.

Figure 6–5.

6-2 SOLA II User Guide Thermo Fisher Scientific

5. The average override is expressed as a percentage of change and

determines when the unit switches to the fast average. As the reading
stabilizes at the new level, the analyzer progressively increases the average
used until it reaches the programmed average time.

Figure 6–6.

6. The fast average time provides the ability to respond to changes faster

without sacrificing stability achieved using a longer average time.

Note Both the regular and fast average times need to be set at multiples of

the injection rate. For example, if the rate is two injections per minute,
averages should be set to 30, 60, 90, 120, 150, 180, 210, or 240 seconds. σ

submenu that allows you to program the dwell time for stream 1 (the
length of time the analyzer stays on stream 1 before it begins monitoring
stream 2). You can then program the dwell time for stream 2 (the length
of time the analyzer stays on stream 2 before returning to stream 1).
Dwell time may be from 1 to 1440 minutes (24 hours).

Figure 6–11.

4. When using the second stream for validation or during the calibration

cycles, it might be desirable to reduce the flow in order to conserve
calibration/validation standards. You can program each stream for high or
low flows. If equipped with the second stream option, the analyzer has
NO and NC pneumatic outputs to control the flow in the sampling
system. The calibration and validation routines always select the low flow.

Figure 6–12.

5. If you select the Timed Stream option, you must also determine how long

the analyzer purges the line before it begins analyzing the other stream.
This period is called the purge time. In respect to calibration, purge time
is how long the analyzer purges the line before it begins analyzing the
calibration stream. You can set the purge time between 1 and 9999
seconds.

Overview

Calibration

The analyzer requires a two-point linear calibration. During the calibration
procedure the average of the raw detector signals corresponding to two
known sulfur concentrations are latched by the unit and retained in non­volatile memory.

During normal operation, the average detector reading is interpolated on the
line to derive the sulfur concentration reported.

The graph below illustrates a SOLA II calibration.

Figure 6–43.

Prior to calibrating the instrument, the sulfur concentration expected at the
two points must be entered in the calibration setup menus (Configuration >

low calibration values.

For the graph above, the values would be:

Low cal value = 10.00 ppm Low cal = 555.600 kHz

High cal value = 100.00 ppm High cal = 15000.000 kHz

The high calibration value needs to be as close as possible to the full range
sulfur concentration expected in the process, and the low calibration value is
normally set to zero so that only one standard is required for calibration.

). In the software, these points are referred to as high and

The values and a graph for a typical calibration are shown below.

Calibration

Performing a high calibration can be achieved in two ways, depending on the
sample conditioning system installed.

The high calibration standard is normally contained in a pressurized cylinder.
The pneumatic output of the analyzer can be used to switch the
corresponding selection valve in the SCS, or the high calibration standard can
be manually introduced to the analyzer. Based on this, the Calibration Setup
menu offers two functions:

λ Calibrate High: Used when the analyzer is expected to switch the valves.

λ Recalibrate High: Used when the calibration standard is introduced

manually to the analyzer.

1. Go to Configuration > Calibration Setup >

. Set the high

calibration value to match the concentration of the standard used.

2. Step down to the Average Cal Readings screen. It is recommended that

you set this value to the maximum (240).

3. Exit the Calibration Setup menu, and go to Configuration > Stream Setup

>

. Set this value. It should be long enough for the unit to
stabilize (time varies depending on the location of the switching valve in
the SCS and the flow rate of the sample). Exit this menu.

4. Go back to the Calibration Setup menu. Step down to the Calibrate High

screen, and press

to perform the calibration.

At this point, the analyzer will energize the calibration solenoid and start a
purge cycle. Once the purge cycle is completed, the detector reading will be
averaged for the programmed number of calibration readings (readings are
performed once a second). The resulting average will be latched to correspond
to the high calibration value concentration.

Density correction is used for reporting the total sulfur in ppm w/w and can
be accomplished using a density transmitter (densitometer) for each stream
with the output connected to the analyzer’s 4–20 mA inputs or by entering a
fixed correction factor.

When using the optional densitometer inputs, the densities that correspond to
4 mA and 20 mA must be entered. The analyzer maintains a moving average
of the 4–20 mA readings and converts the readings to g/cc using a linear
interpolation. The sulfur reading is then corrected by multiplying it by the
ratio between the calibration sample density and the measured density of the
sample.

When the density of the sample is known and remains relatively constant, a
fixed correction factor can be used. In this method, the total sulfur reading is
multiplied by the value entered. If no correction is desired, set the correction
factor to 1.000.

The following provides instructions for both methods. If using a densitometer,
refer to the instructions with Figures 6–59 through 6–63. Menu items for
stream 1 are used.

At Line-Grab Sample

This function was developed primarily for pipeline applications. The sampling
system was designed for the pipeline enclosure in order to provide an
additional pump to facilitate introduction of sample. Access this top-level
menu to enable the analyzer to analyze and report the results of a sample
previously collected from a source other than the regular process input. The
sample to be analyzed is introduced into the instrument in the same manner
that a calibration standard is.

There are three parameters to configure: starting sample ID, average sampling
time, and the relative standard deviation of the samples taken.

1. Each sample is identified with a number (starting sample ID). The

numbers increment sequentially until a new starting sample ID is
programmed.

Figure 9–1.

2. Average sampling time is the number of seconds that the sample is

averaged to compute the result. It can be between 60 and 240 seconds.

Figure 9–2.

Thermo Fisher Scientific SOLA II User Guide 9-1

At Line-Grab Sample

3. The relative standard deviation (RSD) of the samples taken is computed

as a percentage of the computed average. If it is less than or equal to the
programmed value, the analyzer reports a successful sample. If it is
greater than the programmed value, an error is reported.

Leak Tests

Visual Inspection & Cleaning

The analyzer should be inspected occasionally for obvious visible defects, such
as loose connectors, loose fittings, cracked or clogged Teflon lines, and
excessive dust or dirt accumulation. Dust and dirt can accumulate in the
instrument and can cause overheating or component failure. Dirt on the
components prevents efficient heat dissipation and may provide conducting
paths for electricity.

Warning Remove all instrument power before cleaning electronics. σ

The best way to clean the inside of the instrument is to first carefully vacuum
all accessible areas and then blow away the remaining dust with low-pressure
compressed air. Use a soft paintbrush or cloth to remove stubborn dirt.

Use the following leak test procedure to verify that there are no system leaks.

1. Set the sample and air regulators for zero pressure.

2. Replace the tubing from the EXHAUST bulkhead on the left side of the
instrument with a plug.

3. Adjust the auxiliary air regulator for 20 psig pressure.

4. Turn the auxiliary air regulator fully counterclockwise to close the supply
flow.

5. Watch the analyzer pressure for 15 minutes.

6. If the pressure drops significantly, perform the following to locate the
leak:

a. Adjust the sample and air regulators for 20 psig pressure.

b. Check the system fittings with a liquid or electronic leak detector.

c. Correct any leakage.

d. Repeat the leak test.
