INSTALLATION FOR ethanization of unstable gas condensate from the possibility of preliminary degassing

摘要

The invention relates to the field of gas industry and is an improved method of preparation of commercial production of gas condensate deposits. Installation for deethanization (STC) comprises a column 1 deethanizer, the two-phase separator 2, 3, the output of the first three-phase separator 1 is connected to the input of irrigation column 1 deethanizer, the first heat exchanger 4 for heating the STC is set at the input of the second three-phase separator 3, the output of which is connected to the input power deethanizer column 1 through the second heat exchanger 5 to heat the STC, the outlets for gas-phase separators 2, 3 and 1 deethanizer column are connected to drain line 11 deethanizer gases. In this second heat exchanger 3 for heating the STC is a reboiler type heat exchanger for gases whose output is connected to the discharge line 11 deethanizer gases. Due to the presence in the flowsheet exchanger 3 reboiler type useful model allows preliminary degassing unstable gas condensate during the temporary increase in the column load 1 deethanizer, and also due to pre-degassing stabilize the process conditions on the installation deethanizer STC during a temporary increase in the content of methane and ethane NTK.
