FIELD: chemistry.
SUBSTANCE: method involves impulse evaporation of flow discharged from reactor to form upper distillate; further treatment of upper distillate by distillation in standard operational conditions, obtaining acetic acid; running control of acetic acid formation rate by regulation of at least one independent process parametre; running control of acetic acid formation rate by regulation of at least one dependent process parametre; acetic acid formation rate reduction in response to changes in the process course of process equipment state; process control at reduced acetic acid formation rate by regulation of at least one of independent and/or dependent parametre during return of process equipment system to original state of standard operational process before the said change; increase of acetic acid formation rate until the system returns to original state of standard operational process by regulation of at least one of independent and/or dependent parametre, where non-linear multivariant regulation is based on the process model.
EFFECT: improved cost efficiency.
