FIELD: process engineering.
SUBSTANCE: invention relates to release of methanol from water and can be used for preparation of natural gas for processing to prevent formation of crystalline hydrates. Proposed method comprises feeding the methanol solution saturated with water via heat exchanger and scale-control device to rectifier mid section and feeding gas medium to rectifier bottom from evaporator for separation of the mix of methanol and water with subsequent collection of regenerated methanol. Note here that evaporator is combined with rectifiers into one vertical unit. Note also that said evaporator is composed of heat pipe accommodating heating pipe.
EFFECT: decreased overall dimensions and salt deposition.
