STG 654

Gas separator STG 654

STG 654 vertical gas separator is a mechanical device designed to remove and collect solid and liquid impurities existent in the gas flow in order to protect the pipelines, equipment and devices which could be damaged because of particle-contaminated gas.
The STG 654 is a welded construction vessel, inward provided with separation elements such as demister, baffle plate, cyclone, coalescer plates or multicyclone in order to separate impurities. It can be used in the gas regulating and metering stations, gas delivery stations, gas dehydration units, compressor stations etc.
Depending on the equipment provided, the STG 654 can be either a two-phase separator or a three-phase separator.
