Gas analysis Challenges in very harsh process conditions

Full extractive analyzers and insitu analyzers are not suitable for very harsh process conditions where the sample gas is at high temperature, has high dust, has high moisture and very corrosive. 

​

Solution

​

Infra G NDIR multigas analyzer is an exsitu process analyzer that extracts sample from an inertial probe (patent pending) that creates a fast loop and extracts a small flow of clean gas into the analyzer sensors which are mounted in a protected enclosure right at the probe back end. This arrangements avoids sample transport, moisture removal as the inertial probes kept at high temperature separates the dust and moisture from the sample gas.

Product

​

The Infra G Exsitu Series of instruments is designed for on-line analysis of up to five gas phase process components. The system comprises three units: the inertial probe, the Optical Head Unit (OHU).  This instrument operates on the dual wavelength infra-red principle, wherein a beam of specific wavelength infra-red radiation is sent through the simple cell of the Optical Head Unit. The beam is then partially absorbed by the gaseous components to be measured.

The Optical Head Unit (OHU) requires no independent power supply; all necessary power is supplied via the power pack built in the probe head. The OHU Unit displays gas concentration (s) on the integrated monitor along with information on sample conditions, diagnostic data and component trends.

In addition to its auto-zero function, the analyzer has a safety function. In the event of power loss to the Optical Head Unit, or too low or too-high sample temperatures, the control will purge the sample cell with air. This is done in order to prevent any condensation forming in the sample cell, condensates which could be highly corrosive.

There is no moving part in the entire system

Overview

The Infra G features high grade mechanical, optical and electronic components that allows for high performance and reliability. The analyzer is suitable for applications where elevated pressure, temperature, and dust are present. The housing is comprised of a rugged industrial design that conforms to IP65. Network, MODBUS (4) 4-20mA analog inputs, (8) 4-20mA outputs, and configurable relay outputs are available. No sampling system is required, and the low maintenance requirements reduce ownership costs to a minimum.
