Известен способ регенерации водометанольных растворов, по которому при 5-15 С II давлении 1О агм раствор часгичио освобо даюг от сероводорода в выветривателе. Затем раствор подают в атмосферную емкость, откуда насосом нерекачивают в теплообменники типа труба и грубе, где последовательно подогревают регенерира- ванным метанолом и кубовой жидкостью колонны регенерации до 7О С. После этого раствор подают в рекгификациочиую колонну, где оггон кгт метанол. Вмесге с парами мстано.ча с Bejixa колонны отводит- с сероводород. Парь метанола конденсируют в воздушном холодильнике и собирают в емкости , откуда растворенные в метаноле газы (в том числе и HjS ) сдуваютс на факел. Известный способ имеет следующие недостатки . В сырьевом потоке BMbiC раствора содержитс (после pa3ra3HpoBaHHHj до 5 п на 1 л раствора. Попадение сероводорода в ректификационную колонну вызывает повышенную опасность дл обслуживающего персонала, а также коррозию трубопроводов и насосов.There is a method for the regeneration of water-methanol solutions, according to which, at 5-15 C II pressure of 1O agm, the solution frees the hydrogen from hydrogen sulfide in the weathering device. Then, the solution is fed to the atmospheric tank, from where the pump is pumped to heat exchangers such as pipe and coarse, where it is sequentially heated with regenerated methanol and bottom oil of the regeneration column to 7 ° C. After that, the solution is fed to the rectifying column, where it is kg kg methanol. Mstanga with mstano.cha vapors with Bejixa columns removes hydrogen sulfide. The methanol vapor is condensed in an air cooler and collected in containers, from which gases dissolved in methanol (including HjS) are blown off to the flare. The known method has the following disadvantages. The BMbiC solution in the feed stream contains (after pa3ra3HpoBaHHHj up to 5 p per 1 l of solution. The ingress of hydrogen sulphide into the distillation column causes an increased danger for the staff, as well as corrosion of pipelines and pumps.
С целью устранени указанных недостатков по предлагаемому способу сероводород вывод т из системы регенерации путем нагрева раствором паром, отводимым из зоны питани ректификационной колонны в количестве 14-16% от веса раствора,In order to eliminate the above disadvantages of the proposed method, hydrogen sulfide is removed from the regeneration system by heating the solution with steam discharged from the feed zone of the distillation column in an amount of 14-16% by weight of the solution,

В отгонной колонне поддерживают температуру верха 5О и низа 10О С. С верха колонны отбирают сероводорюд, с низа колонны насыщенный раствор метанола под собственным давлением поступает в ко .лонну регенерации. В качестве греющегоPRI and MER. The methanol water solution is saturated with hydrogen sulfide (HMHS), heated in a heat exchanger and fed to a stripping packed column 1y for purification from hydrogen sulfide. In the distant column, the temperature of the top 5O and the bottom 10 ° C is maintained. From the top of the column, hydrogen sulfide is taken, from the bottom of the column a saturated solution of methanol under its own pressure enters the co-lon regeneration. As heating
