Michell Instruments’ QMA601 process moisture analyser has been updated with an option that makes it suitable for continuous catalyst regeneration (CCR) reforming processes.

Its fast response and stable measurements provide operators with reliable moisture control over longer periods without the need for frequent maintenance, according to the company.

In CCR reforming, a moisture analyser is a necessary part of the process to ensure the desired moisture levels remain constant, however, the presence of hydrochloric acid soon compromises sensors, increasing maintenance costs for the operator.

To prevent frequent and expensive maintenance, Michell engineers developed an updated version of the QMA601 which further extends life of the QCM moisture sensor, making the moisture analyser more cost-efficient in the CCR application.

There is also a new sample system option which includes a valve isolating the sample to the sensor while allowing a filter drain/bypass flow to continue to purge through the sample line.

QCM is often specified for gas and petrochemical processing applications, and Michell’s QMA601 process moisture analyser uses this technology, which gives it a lower detection limit of 0.1ppmV and an upper range of 2000ppmV.

The QMA601 analyser has a full-colour touch-screen interface which allows interrogation and operation in situ, with no need for a hot-works permit.

All data logging and readings are easily visible, and the main display also incorporates real-time trend graphing and alarm indicators.

The analyser is fully certified for use in hazardous areas around the world, with accreditations from ATEX, IECEx and cCSAus.
