(54) СПОСОБ ВЫДЕЛЕНИЯ ОКИСИ УГЛЕРОДА ИЗ КИСЛОРОДСОДЕРЖАЩЕГО ГАЗА(54) METHOD FOR EXTRACTING CARBON OXIDE FROM OXYGEN-CONTAINING GAS
1one
Изобретение относитс к способам выделени окиси углерода из кислородсодержащего газа и может быть использовано в химической , нефтехимической и других отрасл х промышленности дл разделени газовых смесей.The invention relates to methods for separating carbon monoxide from an oxygen-containing gas and can be used in the chemical, petrochemical and other industries for the separation of gas mixtures.
.Известен способ выделени окиси углерода из кислородсодержащего газа путем абсорбции раствором двойной соли AlCuClj в толуоле с последующей регенерацией отработанного абсорбента при нагревании; абсорбцию ведут при О-30°С 1.A method is known for separating carbon monoxide from an oxygen-containing gas by absorption with a solution of the double salt AlCuClj in toluene, followed by regeneration of the spent absorbent upon heating; absorption is carried out at O-30 ° C 1.
Однако проведение абсорбции при температуре выше 0°О раствором AlCuCl в толуоле не позвол ет обеспечить безопасность поглощени СО из кислородсодержащего газа вследствие возможности воспламенени толуола, а также снижает экономичность процесса за счет значительного содержани паров толуола в отход щих газах, которые необходимо в дальнейщем конденсировать и поглощать адсорбентом.However, carrying out the absorption at a temperature above 0 ° C with a solution of AlCuCl in toluene does not ensure the safe absorption of CO from the oxygen-containing gas due to the possibility of ignition of toluene, and also reduces the efficiency of the process due to the significant content of toluene vapor in the exhaust gases, which must be further condensed and absorb adsorbent.
Наиболее близким к изобретению по технической сущности и достигаемому эффекту вл етс способ выделени - окиси углерода из кислородсодержащего газа путем абсорбции раствором двойной солиThe closest to the invention in technical essence and the achieved effect is the method of separation - carbon monoxide from oxygen-containing gas by absorption by a solution of double salt
АЮиСЦ в толуоле с последующей регенерацией отработанного абсорбента при нагревании . Абсорбцию ведут при -10-40°С и концентрации раствора двойной соли AlCuCl в толуоле 60-700/0 2.AYuISTS in toluene, followed by regeneration of the spent absorbent when heated. The absorption is carried out at -10-40 ° C and the concentration of the solution of the double salt of AlCuCl in toluene 60-700 / 0 2.
Недостатком известного способа вл етс невозможность обеспечени взрывобезопасности процесса, что обусловлено проведением абсорбции при температурах выще -10°С и возможностью воспламенени паров толуола.The disadvantage of this method is the impossibility of ensuring the explosion safety of the process, which is due to the absorption at temperatures higher than -10 ° C and the possibility of ignition of toluene vapor.

Использование 60-70 /о-ного раствора двойной соли AICuCl4 в толуоле при данных температурах приводит к выпадению твердого осадка, что предопредел ет унос с кислородсодержащим газом твердых час15 тиц, покрытых толуолом, в трубопроводы, где происходит их осаждение и забивка трубопроводов , а также испарение толуола, тем самым создаютс дополнительные :услови взрыЕоопасности и снижаетс надежность процесса.The use of a 60-70 / th solution of the double salt AICuCl4 in toluene at these temperatures leads to precipitation of solid sediment, which predetermines entrainment of solid particles covered with toluene with oxygen-containing gas into the pipelines, where they are precipitated and clogged the pipelines, and evaporation of toluene, thus creating additional: explosive conditions and reducing the reliability of the process.
Целью изобретени вл етс обеспечение взрывобезопасности процесса.The aim of the invention is to ensure the explosion safety of the process.
Поставленна цель достигаетс тем, что согласно, способу выделени окисн углерода из кислородсодержащего газа абсорбThe goal is achieved in that, according to, the method for separating carbon monoxide from oxygen-containing gas is
