Zusammenfassung:FIELD: chemical industry; petrochemical industry; gaseous industry; oil-producing industry; oil-processing industry; installation for purification of the hydrocarbon raw from methanol. ^ SUBSTANCE: the invention is pertaining to the technology of purification of the hydrocarbon raw from methanol and may be used in gaseous, petroleum, petrochemical and chemical industries. The installation includes the assembly of the preliminary separation of the raw connected with the block of the adsorbing purification, the pipeline links and the shut-off-adjusting fittings. The assembly of the preliminary separation includes: the block of the preheating of the raw consisting of the heat exchangers (1) and (2), the rectifying column (3) with the connecting pipes for feeding of the liquid hydrocarbon raw (4), withdrawal of the methanol with the light fraction of hydrocarbons (5) and the withdrawal of the hydrocarbon tailings (6) with the bottom heating, the cooler (10) and container(11). The block of the raw preheating is connected to the connecting pipe (4) of the raw feeding into the rectifying column (3), and the connecting pipe (5) for the raw withdrawal in series through the raw preheating block, the cooler (10) and the container (11) directly connected with the block of adsorbing purification. In the other version the block of the raw preheating is connected to the connecting pipe (4) of feeding of the liquid hydrocarbon raw into the rectifying column (3), and the connecting pipe (5) of withdrawal through the heat exchanger (1) and the cooler (10) is connected to the connecting pipe (23) of the inlet into the extraction column. The connecting pipe (25) of withdrawal of the methanol with the light fraction of hydrocarbons out of the extraction column (20) is connected to the inlet connection pipe (28) of the separator (21), and the connecting pipe (26) of withdrawal of the water-methanol mixture is connected with the intermediate container (22). The connecting pipe (29) of withdrawal of the methanol with the light hydrocarbons from the separator (21) is connected to the block of the adsorbing purification. The connecting pipe (29) of withdrawal of the water-methanol mixture of the separator (21) is connected to the intermediate vessel (22), which outlet is connected to the feeding line of the extracting liquid into the extraction column (20). The invention reduces the operational costs, increases the lifetime of zeolite. ^ EFFECT: the invention ensures reduction of t
