1.1 Description

The Rosemount™ CT5400 Continuous Gas Analyzer, hereafter referred to as the Rosemount CT5400 or the analyzer, is an electronic sensor that uses laser spectroscopy to perform analysis of process gas streams.
The function of the analyzer is to detect and measure up to twelve different types of gas at concentrations ranging from parts per million (ppm) to percentage levels in the process gas stream. The analyzer is designed to be mounted in a standard 482.6 mm (19 in.) rack.
WARNING!
HEAVY ITEM Handle the analyzer with caution during unpacking, installing, maintaining, and transporting to prevent crushing of hands, feet, or other body parts.

Plan

1.2
The analyzer weighs 31 kg (68 lb). Emerson™ recommends that the analyzer is only moved and lifted by a minimum of two people. Wear suitable protective gloves and protective footwear.
Failure to properly handle the analyzer may cause injury to personnel.
This manual is intended for the personnel who install, operate, and maintain the equipment.

Equipment purpose and role

The analyzer is a gas sensor system that can be configured to measure the concentrations of multiple small molecules in a gas sample that is provided to the analyzer via a sample line.
The types of molecules that are measured depend on the system configuration.
Installation, Operations, and Maintenance Manual 1
Plan
Rosemount CT5400Figure 1-1:
The analyzer can be configured to detect and measure up to twelve different gases, depending on the combination of laser modules fitted.

1.3 System overview

A complete Rosemount CT5400 system consists of a gas handling system, the analyzer, and the associated interconnecting wiring and gas piping.
Measurement data from the analyzer can be displayed in the process control center. You must provide the gas handling system and interconnecting wiring and gas piping; Emerson supplies the CT5400.
In Figure 1-2, the items supplied by Emerson are colored orange; the items supplied by you are colored blue. Table 1-1 lists the main items of the system.

A. Gas handling system B. Sample supply line C. Sample return (exhaust) line D. Rosemount CT5400 Gas Analyzer E. Electrical power F. Measurement data G. Control center
The analyzer contains an optical system with multiple lasers and a series of optical components that provide an optical path, a heated multi-pass analysis cell, and sample and outlet ports that can be connected to a gas handling system, and control and analysis electronics. The number of lasers installed depends upon customer requirements. The complete system operates from a 240 Vac 50 Hz supply.
Gas concentrations are measured using mid-infrared optical absorption spectroscopy. The light sources are quantum cascade lasers (QCLs), which are operated to produce wavelength 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 Section 1.9 before entering the analyzer. Detailed characteristics of the analyzer are also given in Section 1.9.

1.9.1 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 2 m and 5 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.

6 Gas Calibration Procedures

6.1 Required tools

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, where 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.

Gas Calibration Procedures

6.2
If calibration must be carried out (e.g., for legal requirements), it can be calibrated by using a water vapor generator to supply a known concentration of water vapor.

6.3 Calibration

Calibration flows the known cylinder gas through the analyzer and then adjusts the readout until the measurement matches the cylinder. This adjustment is then applied to all measurements until the next calibration. There are two circumstances in which you may want to calibrate.
1. After you verify (see Chapter 5) and find that the analyzer readings are outside of
tolerance
2. At regular intervals, such as once a day or once a shift

6.3.1 Zero calibration

Zero calibration is calibrating the analyzer so that when no sample gas is flowing through it, the gas concentrations measured by the instrument are zero. Zero calibration is done by calibrating the analyzer measurements against a known sample gas using the following procedure:
Prerequisites
Run the analyzer at a stable temperature for at least thirty minutes prior to commencing this procedure.
Use nitrogen gas of instrument gas purity as the zero calibration gas.
Procedure
1. Make sure that a pressure regulator is connected to the nitrogen gas bottle.
2. Connect a hose from the nitrogen gas bottle through a T-piece to the sample supply
port on the rear of the analyzer. Connect an excess flow line to the unused port on the T-piece and route the excess flow line to a suitable extractor.
3. On the display controller of the analyzer, browse to the Main menu as described in
