FIELD: chemistry.
SUBSTANCE: invention relates to chemistry. stream of methanol material reacts with oxygen and optionally a temperature regulator in a partial oxidation reactor to obtain a stream of synthetic gas. The partial oxidation reactor has a burner in an open uncatalysed gas generator with free flow and works in the 1100-2000 °C temperature interval. The synthetic gas stream is divided into a stream with high carbon dioxide content and a mixed stream containing hydrogen and carbon oxide which is then divided into a stream with high hydrogen content and a stream with high carbon oxide content. Re-equipment of the initial installation for producing methanol to an installation for synthesis of acetic acid involves the following steps: provision for the initial installation for producing methanol, having at least one partial oxidation reactor for converting hydrocarbon into a synthetic gas stream and a methanol synthesis loop for converting hydrogen and carbon oxide from the synthetic gas stream to methanol, supply of at least one portion of methanol material stream, oxygen from an air separation unit and, optionally, a temperature regulator, into at least one partial oxidation reactor, mounting the first separation unit for separating a stream with carbon dioxide content and a mixed stream of hydrogen and carbon oxide from the outgoing synthetic gas stream, mounting the second separation unit for separating a stream with high hydrogen content and a stream with high carbon oxide content from the mixed stream, mounting the acetic acid synthesis installation, supplying a stream with high carbon oxide content from the second separation unit and a portion of methanol material stream into the acetic acid synthesis installation and fitting isolation valves for isolation of the methanol synthesis loop from the remaining part of the reconstructed installation.
EFFECT: invention increases cost-effectiveness of the process.
