Изобретение относитс к области аосорбционных методов очистки природного газа от кислых соединений, налример сероводорода и углекислого газа.The invention relates to the field of aosorption methods for the purification of natural gas from acidic compounds, the hydrogen sulfide and carbon dioxide nalimer.
Известен способ очистки газов от кислых соединений, например сероводорода, углекислого газа, абсорбцией водными растворами арсенатов и арсенитов щелочных металлов.A known method of cleaning gases from acidic compounds, such as hydrogen sulfide, carbon dioxide, absorption of aqueous solutions of arsenate and arsenite of alkali metals.
Также известен способ очистки газов от кислых соединений, например сероводорода, углекислого газа, лутем абсорбции их метанолом при температуре от -60 до -70°С. Недостатками опособа вл ютс большие потери метанола из-за его низкой температуры кипени (64,7°С) токсичность и коррозийность абсорбента .Also known is a method of purifying gases from acidic compounds, for example hydrogen sulfide, carbon dioxide, by absorbing them with methanol at a temperature of from -60 to -70 ° C. The disadvantages of this method are the large losses of methanol due to its low boiling point (64.7 ° C) toxicity and corrosivity of the absorbent.
С целью устранени указанных недостатков предложен способ очистки природного газа от кислых компонентов, например сероводорода и углекислого газа, в котором в качестве абсорбента иопользуют уксусный аигидрид . Уксусный ангидрид кипит ори температуре 140°С, не коррозиен, не токсичен. По предложенному способу очистке подвергают бытовой газ с содержанием сероводорода 6- 8 и углекислого газа 56-57 об. %.In order to eliminate these drawbacks, a method has been proposed for purifying natural gas from acid components, for example, hydrogen sulfide and carbon dioxide, in which acetic acid hydride is used as an absorbent. Acetic anhydride boils at a temperature of 140 ° C, non-corrosive, non-toxic. According to the proposed method, household gas with hydrogen sulfide content of 6–8 and carbon dioxide gas of 56–57 vol. %
Одновременно с процессом очистки происходит осушка газа, так как вода при комнат2Simultaneously with the cleaning process, the gas is dried, as the water in rooms 2
ной температуре реагирует с уксусным ангидридом .Noah reacts with acetic anhydride.
Пример 1. В стекл нный реактор высотой 500 и диаметром 300 мм с насадкой (рифленые керамические цилиндры размером 8Х Х10 мм) загружают 150 см уксусного ангидрида и при комнатной температуре и атмосферном давлении пропускают бытовой газ с содержанием сероводорода 6-8 об. %. Степень очистки природного газа от сероводорода провер ют качественной реакцией с уксуснокислым свинцом или нитропруссидом натри , количественно - йодометрически.Example 1. A glass reactor with a height of 500 and a diameter of 300 mm with a nozzle (corrugated ceramic cylinders 8X X10 mm in size) is loaded with 150 cm of acetic anhydride and household gas with a hydrogen sulfide content of 6-8 vol. % The degree of purification of natural gas from hydrogen sulphide is checked by qualitative reaction with lead acetate or sodium nitroprusside, quantitatively by iodometry.
Поглотительна способность уксусного ангидрида при этих услови х составл ет 91 см H2S на 100 см растворител .The absorption capacity of acetic anhydride under these conditions is 91 cm H 2 S per 100 cm of solvent.
Пример 2. В услови х примера 1 очистке подвергают углекислый газ из баллона с содержанием СОз 57 об. %.Example 2. Under the conditions of example 1, carbon dioxide gas is purified from a cylinder with a CO2 content of 57 vol. %
Степень очистки при этом определ ют помутнением раствора СаО (выпадением осадка CaOOg).The degree of purification is determined by the turbidity of the CaO solution (precipitation of CaOOg).
Поглотительна способность уксусного ангидрида при этих услови х составл ет 400 см СО2 на 100 см растворител .The absorption capacity of acetic anhydride under these conditions is 400 cm CO2 per 100 cm solvent.
