FIELD: oil and gas industry.SUBSTANCE: invention refers to gas industry and can be used at gas condensate fields, immediately at sites of gas preparation for transportation or at centralised sites of preparation of instable gas condensate for transportation or processing. The invention refers to the method of obtaining liquid ethane from instable gas condensate, which involves separation of gas condensate in a rectifying column into three flows, two gas ones - methane and ethane, and one liquid - deethanised condensate, ethane gas flow separation with a side shoulder of the rectifying column, which is located on the level of gaseous phase containing ethane free from methane, and further condensation of ethane flow and extraction of liquid ethane from condensed ethane flow.EFFECT: enlarging the range of products, improving their quality and low-temperature properties.1 ex |
