摘要： Process and plant for refining a stream of crude methanol (103), comprising: pre-treatment of the crude methanol in a topping stage (100), for the separation of volatile components, at a defined topping pressure (p1); distillation of methanol with at least one final distillation step of methanol at a defined distillation pressure (p4), in which said distillation pressure (p4) is greater than the topping pressure (p1), and in which a gaseous stream of distilled methanol (440), which is produced in the final distillation step, is used to supply at least part of the heat for the pre- treatment topping step.
