Zusammenfassung:There is proposed an efficient recovery of methanol from waste gases loaded with methanol in an integrated flow chart for the production and processing of methanol. The methanol fractions separated from the waste gases are recovered within the already existing, distillative processing of the crude methanol to pure methanol, so that no separate apparatuses are required for the recovery of the methanol from the loaded scrubber waste waters. The valuable substance methanol is recovered and the impact on the environment is reduced. By means of particular aspects of the invention the need for water as washing agent can be reduced further.
