FIELD: process engineering.
SUBSTANCE: invention can be used in gas processing intended for prevention of crystalline hydrate formation. Methanol recovery unit comprises tank for water-saturated methanol, heat exchanger, scale control device, rectifier, recovered methanol accumulator, evaporator composed of heat pipe accommodating heating tubes and evaporator downcomer tube to feed gas into said rectifier, and combustor. Note here that rectifier, evaporator and combustor make an integral vertical unit.
EFFECT: minimised scaling, decreased overall dimensions.
