METHOD OF RUNNING OF INDUSTRIAL PLANT FOR PREPARATION OF GAS AND INDUSTRIAL PLANT FOR PREPARATION OF GAS Russian patent published in 1994 - IPC

FIELD: gas production. SUBSTANCE: gas is compressed, cooled, separated and supplied for cleaning. After cleaning oil gas containing up to 20 volume per cent of CO₂ is separated into hydrocarbon gas and CO₂. Hydrocarbon gas is supplied to user and CO₂ is released into atmosphere. If after separation gas contains more than 20 volume per cent of CO₂ it is used as flow for additional compression and pumping into seam with drying between stages of compression. Industrial plant for preparation of gas includes compressors, cooler, separator, absorber, pump, vessel for amine, desorber, heat exchanger. It is supplemented with weathering unit and six-stage compressor. EFFECT: improved efficiency of gas preparation. 2 cl, 1 dwg
