To establish purity and optimise process control in industrial processing applications such as ethylene, natural gas and hydrogen manufacturing, Emerson Automation Solutions has announced the Rosemount CT5800 continuous gas analyser.

The CT5800 is the first Quantum Cascade Laser (QCL) analyser designed for industrial process applications requiring Class I, Division 2 hazardous area certification built within a flameproof enclosure.

The CT5800 analyser’s unique cell design enables high-accuracy measurement of concentrations of impurities down to low ppm levels in the gas streams with exceptional linearity of response and repeatability, and incorporates up to six laser modules housed inside the same enclosure.

The CT5800 analyser can measure up to twelve components simultaneously, greatly reducing the need for multiple analysers. In addition, the CT5800 has no consumables and calibration is seldom required, keeping cost of operation low.

“In ethylene manufacturing and natural gas processing for example, establishing the purity of the gas is essential to meeting contractual requirements as well as maintaining process optimization and safety. Operators need to perform this analysis as accurately as possible – without wasting time or money,” said Amanda Gogates, product manager for Rosemount Quantum Cascade Laser Analyzers, Emerson Automation Solutions.
