FIELD: oil and gas industry.
SUBSTANCE: invention is related to oil and gas production industry. Invention is referred to device for preparing a mixture of gaseous hydrocarbons for transportation purpose; the device contains series-connected pipeline for source raw material delivery, the first separator, the second separator, the first recuperative heat exchanger 4, recuperative heat exchanger 9 connected to deethaniser column. Liquid phase output of deethaniser column is connected to the medium part of stabiliser which propane-butane faction output is connected through the second recuperative heat exchanger 13 to the first aromatisation reactor which output is connected to the second aromatisation reactor which output through the above second recuperative heat exchanger 13 is connected to separators 24 and 17; the second separator is connected through the third recuperative heat exchanger 19 to liquid phase in the medium part of fractioning column which output of aromatic hydrocarbons concentrate is connected to pipeline of aromatic hydrocarbons concentrate at the warehouse. Insert for hydrate inhibitor delivery is made between the first separator and the first recuperative heat exchanger 4.
EFFECT: transportation of hydrocarbons in cold region conditions.
