Description
Изобретение относитс к очистке газа от сероводорода и может быть использовано в нефте- и газодобывающей химической, нефтехимической и других отрасл х промышленности .The invention relates to the purification of gas from hydrogen sulfide and can be used in the oil and gas chemical, petrochemical and other industries.
Целью изобретени вл етс повышение поглотительной способности и селективности по сероводороду.The aim of the invention is to increase the absorption capacity and selectivity for hydrogen sulfide.
Пример. При приготовлении абсорбента моноэтаноламин (МЭА), этиленгликоль (ЭГ) и воду смешивают в предлагаемых количествах.Example. In the preparation of the absorbent monoethanolamine (MEA), ethylene glycol (EG) and water are mixed in the quantities offered.
В поглотительную стекл нную колонку, снабженную вод ной рубашкой дл термо- статировани и перегородками из пористого стекла в верхней и нижней част х, заливают состав, содержащий, мас.%: МЭА 10, ЭГ 10. вода 80, в количестве 20 мл. В термостате устанавливают температуру 30°С и пропускают газ, содержащий сероводород 0,05 об.% и диоксид углерода через колонку со скоростью 50-60 см /мин. Степень насыщени поглотительного раствора сероводорода, а также содержание кислыхA composition containing, in wt.%: MEA 10, EG 10, water 80, in an amount of 20 ml is poured into an absorption glass column equipped with a water jacket for thermostatting and porous glass partitions in the upper and lower parts. The thermostat is set to a temperature of 30 ° C and a gas containing 0.05% by volume of hydrogen sulfide and carbon dioxide is passed through the column at a speed of 50-60 cm / min. The degree of saturation of the absorption solution of hydrogen sulfide, as well as the acid content
газов (сероводород, двуокись углерода) в исходном газе определ ют хроматографиче- ским методом.gases (hydrogen sulphide, carbon dioxide) in the source gas are determined by chromatography.
Результаты, полученные при исследовании различных составов, приведены в таблице .The results obtained in the study of various compositions are given in the table.
Предложенный абсорбент при его внедрении обеспечивает технико-экономический эффект за счет повышени поглотительной способности и селективности по сероводороду.The proposed absorbent, when introduced, provides a technical and economic effect by increasing the absorption capacity and selectivity for hydrogen sulfide.
