2 Theory of operation

2.1 Overview

The Rosemount™ CT5100(Ex) is a gas sensor system that can be configured to measure the concentrations of multiple small molecules carried in the gas sample. The types of molecules that are measured depend on the system configuration.
The analyzer can be configured to detect and measure up to 10 gases, with ranges varying from volume to percent (%) volume levels. A detailed description of the system is given in
Detailed system specifications .

2.2 Laser measurement principle

The Rosemount CT5100(Ex) can use up to six lasers to detect and measure gases. Each laser can measure between one and three gases. Inside the laser, which is about the size of a pin head, electrons cascade down a series of quantum wells, producing a photon at each step.
This cascade of electrons can produce between 20 and 100 photons per electron, giving the lasers a higher output power than traditional semi-conductor lasers.
The lasing wavelength of the laser is determined by adjusting the physical thickness of the semiconductor layers, giving access to high power lasers covering the mid-infrared spectral region. The lasers have no need for cryogenic cooling, have excellent spectral quality in chirped mode, and have good tuneability.

2.3 Gas concentration measurements

In the Rosemount CT5100(Ex), gas concentrations are measured using optical absorption spectroscopy. The laser light sources are operated to produce wavelength sweeps that cover the absorption lines of the gases to be measured.
Sample gas, which may contain impurity gases that are to be detected and measured, is conditioned and drawn into the analyzer. Inside the analyzer, the sample gas is fed into an analysis cell, where the beams from the laser are passed through the gas. The analysis cell contains a set of mirrors that bounce the light back and forth many times, which lengthens the path of the lasers through the gas.
On exiting the analysis cell, the light is detected by a receiver unit. The variation in the intensity of light in the vicinity of absorption lines for the gases being detected is measured, and the concentration is determined using a comprehensive spectral fitting routine.

sweeps that cover the absorption lines of the gases. The light from each laser is routed through an optical path to the analysis cell, which provides measurement of low concentrations of the subject gases. An external sample handling system conditions the sample gas and draws it through the analysis cell. The light exits the multi-pass analysis cell and is directed to a receiver in the analyzer. The variation in the intensity of light in the vicinity of the absorption lines is measured, and the concentration is determined using a comprehensive spectral fitting routine.
There is no sample conditioning provided within the analyzer; the sampled gas must be brought within the parameters shown in Detailed system specifications before entering the analyzer. Detailed characteristics of the analyzer are also given in Table 4-1.

Description

3.5 Optical description

The laser modules are located in the core of the analyzer. Each laser module produces a separate light beam, and these beams are combined linearly as the modules are aligned in the system. The combined beams are closely coupled, parallel, and coaxial about a virtual line. The laser light beams pass through a baseplate onto an optical steering assembly, which directs the laser beam through the sample cell.
The sample cell contains a set of mirrors to create a path through the sample gas that is between 0.7 ft. (0.2 m) and 49.2 ft. (15 m) through multiple reflections along the length of the cell. The laser beams exit the cell at the opposite end from where they entered and are directed using a second optical block to a receiver.
By measuring and analyzing the light detected by the receiver unit, it is possible to accurately determine the concentrations of the target molecules within the gas sample cell.
3.5.1

Explosion protection

The process gas stream being analyzed is highly flammable and explosive, as are other gases that could, in the event of a gas escape, be present around the analyzer. To prevent fires or explosion in the event of a gas escape, the analyzer has been designed to meet industry standard requirements for explosion protection.
A zonal approach to explosion protection has been adopted. A sample of the process gas stream passes through the analysis cell, and therefore the analysis cell is a sealed unit. The optical compartment is not airtight, and, in the event of a gas escape, flammable and explosive gases could enter the optical compartment. To prevent electrical ignition of a gas escape, all electrical components in the optical compartment (the pressure sensor, temperature sensor, and block heater) have been certified as safe for use in explosive

atmospheres. The components in the optical compartment are mounted on a metal baseplate that is sealed to prevent gases from entering the electrical compartment.
The electrical compartment contains a PC and numerous electrical/electronic components that are not certified for use in hazardous atmospheres. To prevent explosive gases from entering the electrical compartment, it is sealed and held at a positive air pressure - above the surrounding air pressure - when the analyzer is switched on.

9.2 Shutdown procedure

To shut down the analyzer:
DANGER
EXPLOSION HAZARD
Unauthorized operation of the gas handling system when maintenance is being performed on the analyzer or on its associated pipes/hoses may result in gas being released, causing fire or explosion. Failure to lock out gas handling system may cause death.
Always lock lock out the gas handling system when shutting down the analyzer.
Procedure
1. Shut down the gas handling system that conditions the sample gas and feeds it to
the analyzer. Always lock-out the gas handling system to prevent its unauthorized operation during maintenance, which may cause an escape of gas.
DANGER
EXPLOSION HAZARD
Failure to vent sample gas may cause death.
Vent the sample gas in the system to prevent fire or explosion during maintenance and to prevent damage to the analyzer during shutdown.
Purge the sample gas in the pipes leading to the analyzer to prevent hazards to personnel during maintenance.
Purge the sample gas in accordance with safe working procedures for the site. Allow the analyzer and system for returning the sample gas to run for five
minutes to allow any sample gas in the analyzer to be returned to the exhaust.
2. Purge any sample gas in the pipe/hose from the gas handling system to the analyzer
using factory air or nitrogen supply.
3. Allow the analyzer to run for five minutes with the purge gas connected, so that any
sample gas in the analyzer is vented to the exhaust. On the display controller, check that the gas concentrations read 0 ppm before stopping the purge flow.
WARNING
HIGH PRESSURE GAS AND AIR
The calibration gas supply and compressed air supply operate at a pressure that can cause injury (e.g. damage to eyes and skin punctures from debris blown by the high pressure gas or compressed air).
4. Turn off the calibration gas supply to the analyzer. Lock out and tag out the
compressed air supply.

10 Gas calibration

10.1 Required tools

The gas concentrations measured by the analyzer can be validated against a known sample gas or calibrated to match it by using the following gas calibration procedure.
To calibrate the analyzer, you need the following items:
Nitrogen gas of "instrument gas" purity for use as a zero calibration gas
Suitable span calibration gases for each gas measured
Gas bottle pressure regulators
Interconnecting hoses to connect the gas bottles to the analyzer
A T-piece and excess flow line
NOTICE
In the case of gases, such as H2O, for which it is not normally possible to obtain calibrated gas cylinders, it will usually be measured by the same laser as some other gas. Validating the other gases measured by the analyzer (particularly any which are measured by the same laser as H2O) can demonstrate that the system is functioning correctly, meaning there is no need to calibrate the water measurement directly.
If you need to calibrate (e.g., for legal requirements), you can use a water vapor generator to supply a known concentration of water vapor.
The validation procedure is essentially the same as the calibration procedure, except that it does not adjust the analyzer measurements to match the calibration standard.
CAUTION
EQUIPMENT DAMAGE
DO NOT, under any circumstances, press the top two buttons on the display controller simultaneously. This will override the system code supplied with the analyzer and display the default program screen for the controller.
This will lock the software controlling the analyzer requiring the analyzer to shut down externally and restart, risking a possible corruption of the software and loss of the analyzer operation during the shutdown and restart process.
It is essential that only trained, qualified personnel operate the controls on the analyzer. Failure to follow may cause warranty invalidation, property damage, and/or personal injury
or death.
