Gas processing plant in natural gas production

From instrumentation to fully engineered metering systems

In a gas processing plant, raw natural gas is converted into pipeline quality dry natural gas by removing impurities such as solids, water, carbon dioxide (CO2), hydrogen sulfide (H2S), mercury and higher molecular mass hydrocarbons such as natural gas liquids (NGLs). With many different configurations possible, a generalised version of a gas processing plant is shown here.

KROHNE offers a full portfolio of instrumentation for gas plants, ranging from straightforward pressure or temperature transmitters to high accuracy volume or mass flow measurement of auxiliary process media - such as amine, glycol and nitrogen. For natural gas and natural gas liquids (NGL) we offer process and Custody Transfer ultrasonic flowmeters and Coriolis mass flowmeters, extending up to fully engineered turn-key metering systems.
