SERVOPRO Chroma offers flexible measurement in cryogenic ASU production


UK-based Servomex is offering cryogenic ASU operators increased flexibility in their operations, with the launch of its new SERVOPRO Chroma.

Combining the latest Plasma Emission Detector technology with improved operational and communications capabilities, the SERVOPRO Chroma gives total flexibility in measuring hydrocarbons present in ambient air.

Constant hydrocarbon measurement is crucial in ASU production, as hydrocarbons that build up in the cryogenic portion of the process pose an explosion risk when mixed with enriched air or pure oxygen.

Depending on the results of an ambient air test to determine the types and level of hydrocarbons present, plant operators must decide whether to measure for Total Hydrocarbons Measurement (THC), methane and non-methane hydrocarbons (CH4 & NMHC), or measure for individual hydrocarbons including methane, acetylene, propane, propylene, ethane and ethylene.
