FIELD: power engineering.
SUBSTANCE: method to produce liquefied hydrocarbon gases includes stabilisation of a deethanised gas condensate by extraction of hydrocarbon gases from it, their cooling, mixing of liquefied hydrocarbon gases (LHG) with water, washing of methanol and phase separation into LHG and a water-methanol solution. At the same time at the washing stage the mixture of LHG with water is dispersed in water phase, then coalescence of finely dispersed drops of the water-methanol solution is carried out, afterwards phase separation is carried out. A plant to produce liquefied hydrocarbon gases comprises the following serially joined components: a rectification tower of gas condensate stabilisation, a cooling device, a mixing device, at least one reservoir for methanol washing and a separating reservoir. At the same time at least one reservoir for methanol washing and the separating reservoir are arranged in the form of sections of a reservoir filter, separated by two partitions with coalescent filter cartridges installed in them to form three sections in the inner cavity of the specified filter, besides, two sections represent reservoirs of methanol washing, and the third section - a separating reservoir.
EFFECT: using the invention will make it possible to minimise capital and current costs for a plant due to its simplification.
