FIELD: gas treatment. SUBSTANCE: natural gas is divided into two streams: 1 and 2. Stream 2 is brought into contact with recycling liquid phase containing water and solvent to form aqueous liquid phase with low solvent content and solvent-containing gas phase, which phases are separated by settling. Aqueous phase is then brought into contact with one of two initial gas streams containing no solvent. The latter is extracted with gas from solvent-depleted aqueous phase to give solvent-rich gas phase and regenerated liquid aqueous phase. Solvent-depleted gas stream 1 is mixed with gas phase after contact stage. Gas phase is cooled by partial condensation into solvent-containing aqueous phase and into hydrocarbon phase to give final treated gas containing no water and no higher hydrocarbons. Solvent- containing aqueous phase is recycled within system. EFFECT: enabled dehydration of natural gas with simultaneous removal of higher hydrocarbon impurities at lower power consumption and lower investments. 16 cl, 3 dwg, 1 tbl, 3 ex
