1. Способ получения уксусной кислоты, предусматривающий стадии каталитического превращения синтез-газа, богатого водородом и окисью углерода, в поток продукта, содержащий метанол, простой диметиловый эфир и воду, каталитического взаимодействия метанола и простого диметилового эфира в потоке продукта с моноокисью углерода и извлечения из продукта, полученного таким образом, потока, состоящего, в основном, из уксусной кислоты, отличающийся тем, что поток продукта подвергают охлаждению с последующим разделением на жидкую фазу, содержащую метанол, простой диметиловый эфир и воду, которую подвергают реакции с моноокисью углерода, и газообразную фазу, содержащую моноокись углерода и остаточные количества простого диметилового эфира, которую выводят из процесса, причем на стадии карбонилирования добавляют моноокись углерода.1. A method for producing acetic acid, comprising the steps of catalytically converting a synthesis gas rich in hydrogen and carbon monoxide into a product stream containing methanol, dimethyl ether and water, catalyzing methanol and dimethyl ether in a product stream with carbon monoxide and recovering from the product thus obtained, a stream consisting mainly of acetic acid, characterized in that the product stream is cooled, followed by separation into a liquid phase containing etanol, dimethyl ether and water, which is reacted with carbon monoxide and a gaseous phase comprising carbon monoxide and residual amounts of dimethyl ether, which is removed from the process, and added to the carbonylation step the carbon monoxide. 2. Способ по п. 1, отличающийся тем, что перед введением синтез-газа на первую стадию реакции разделяют газ на первую часть, которую подают на первую стадию реакции, и вторую часть, которую обрабатывают для извлечения содержащейся в ней моноокиси углерода, которую вводят на стадию карбонилирования. 2. The method according to p. 1, characterized in that before introducing the synthesis gas into the first reaction stage, the gas is divided into a first part, which is supplied to the first reaction stage, and a second part, which is treated to extract the carbon monoxide contained therein, which is introduced to the carbonylation step. 3. Способ по п. 2, отличающийся тем, что извлечение моноокиси углерода из синтез-газа осуществляют посредством мембранного разделения. 3. The method according to p. 2, characterized in that the extraction of carbon monoxide from the synthesis gas is carried out by membrane separation. 4. Способ по п. 2, отличающийся тем, что извлечение моноокиси углерода из синтез-газа осуществляют посредством криогенного разделения. 4. The method according to p. 2, characterized in that the extraction of carbon monoxide from the synthesis gas is carried out by means of cryogenic separation. 5. Способ по п. 2, отличающийся тем, что поток синтез-газа разделяют на первую и вторую части в объемном отношении между 0,5 : 1 и 2 : 1. 5. The method according to p. 2, characterized in that the synthesis gas stream is divided into first and second parts in a volume ratio between 0.5: 1 and 2: 1.
