Abstract
Described is a process for degasolining by refrigeration of a gas containing condensable hydrocarbons, which is effected in the presence of methanol to avoid the formation of hydrates, said process making it possible to at least partially recover the methanol entrained in the gas, by washing same by means of a liquid hydrocarbon fraction. The process described thus makes it possible to avoid having to compensate for the loss of methanol by a continuous make-up, as is the case with conventional processes. It accordingly enjoys enhanced levels of performance and economy.
