Description
(54) СПОСОБ ОЧИСТКИ ПРИРОДНОГО ГАЗА ОТ Изобретение относитс к способам регенерации растворов, получаемык при очистке газа от сероводорода и может примен тьс в газовой, нефт ной и химической отрасл х промышленности. Известны способы регенерации отработанных погпотитепьных растворов, содержащих сульфид железа путем окислени последнего кислородом воздуха до элементарной серы. Образующа с элементарна сера флотируетс избыточным воздухом и выводитс из системы в виде сер ной пены i, Недостаток способов заключаетс в том, что вместе с элементарной серой .из поглотительных растворов извлекаетс и гидроокись железа.чго приводит к загр знению серы и большим потер м гидро окиси железа. Наиболее близким к предлагаемому изобретению по технической сущности и достигаемому результату вл етс способ очистки природного газа от сероводорода путем абсорбции гиароокисью железа с СНРОВОДОРОДАо последующей регенерацией отработанного поглотител продувкой воздухом в эжекторе . Полученна сера затем флотируетс воздухом и удал етс нз системы в виде серной пены 2. Недостатком этого способа вл етс то, что в состав серной пены вкодит до 2О% гидроокиси железа, что п шводит к потер м гидроокиси железа в к удорожа-. нию процесса. Кремле того, наличие в серной пене гидроокиси железа загр зн ет элементарную серу и ухудшает ее качество , что также снижает технико-экономические показатели способа. Цель изобретени - исключение потерь гидроокиси железа при регенерации. Поставленна цель достигаетс способом очистки природного газа от сероводорода путем абсорбции гидроокисью железа с последующей регенерацией отработанного поглотител продувкой воздухсм с образованием смеси элементарной серы и гидроокиси железа, в котором полученную после регенерации смесь обрабаты(54) METHOD FOR CLEANING NATURAL GAS FROM THE INVENTION The invention relates to methods for regenerating solutions that are obtained by purifying gas from hydrogen sulphide and can be used in the gas, oil and chemical sectors of the industry. Methods are known for the regeneration of waste solutions containing iron sulfide by oxidation of the latter with oxygen to elemental sulfur. The formed sulfur is floated with excess air and removed from the system as sulfur foam i. gland. The closest to the proposed invention to the technical essence and the achieved result is a method of purification of natural gas from hydrogen sulfide by absorption of iron hydroxide with hydrogen hydrogen sulfide followed by regeneration of the spent absorber by blowing air into the ejector. The resulting sulfur is then floated with air and removed from the system in the form of sulfur foam 2. The disadvantage of this method is that sulfuric foam contains up to 2% of iron hydroxide, which leads to a loss of iron hydroxide in the higher cost. process. Moreover, the presence of iron hydroxide in sulfur foam foam contaminates elemental sulfur and deteriorates its quality, which also reduces the technical and economic performance of the process. The purpose of the invention is to eliminate the loss of iron hydroxide during regeneration. The goal is achieved by the method of purifying natural gas from hydrogen sulphide by absorption of iron hydroxide with subsequent regeneration of the spent absorber by blowing air into a mixture of elemental sulfur and iron hydroxide, in which the treatment mixture obtained after regeneration
