FIELD: oil and gas industry.
SUBSTANCE: four versions of plant are proposed, consisting of input separation units, gas treatment, condensate stabilisation and catalytic processing. During operation of the first plant verison, the raw gas is separated in the input separation unit to produce the water condensate, discharged from the unit, the separation gas supplied to the gas treatment unit, and the condensate supplied to the condensate stabilisation unit after mixing with a wide fraction of light hydrocarbons, supplied from the gas treatment unit. Stable condensate is discharged from the condensate stabilisation unit, and the stabilisation gas is supplied to the catalytic processing unit, from which at least one liquid product of catalytic processing is withdrawn, and the catalytic processing gas is supplied to the gas treatment unit, from which the commercial gas is withdrawn. During operation of the second and fourth verisons, the catalytic processing gas is supplied to the commercial gas exhaust line, and during operation of the third and fourth plant verisons, at least a portion of the liquid product from the catalytic processing unit is supplied to the condensate exhaust line.
EFFECT: reducing energy costs and expanding the range of products.
