Description

39,75 вес. % N-метилпирролидона, 59,75 вес. % Д ЭТИ ле  гликол  и 0,5 :зес. % воды. Услови  опыта по примеру 1.39.75 weight. % N-methylpyrrolidone, 59,75 weight. % D THIS le glycol and 0.5: hz. % water. The conditions of the experiment in example 1.

Дри температуре абсорбци  40, 20, О и минус 20° С получают еоответствен-но температуры точки росы осушенного газа: минус 14,5, минус 24,9, минус 35, минус 45,7° С.A dry absorption temperature of 40, 20, O and minus 20 ° C is obtained according to the dew point temperature of the dried gas: minus 14.5, minus 24.9, minus 35, minus 45.7 ° C.

Предлагаемый абсорбент при 0° С обеспечивает точку росы осушенного газа в зависимости от содержани  диэтиленгликол  минус 29 и минус 35° С, в то врем  как из:ве спный С0|р|бент - минус 25,9° С. СтепеНь .«олверсии сероводорода .в серу при иасышении абсорбепта двуокисью серы составл ет 99,72%.The proposed absorbent at 0 ° C provides the dew point of the dried gas depending on the content of diethylene glycol minus 29 and minus 35 ° C, while from: a cold C0 | p | bent - minus 25.9 ° C. StepperS. . in sulfur, with absorption of sulfur dioxide absorbed is 99.72%.

Таким образам, иснользо-вание предлагаемого абсорбента позВОл ет повысить степень осушки газа, исключить применение низкокип щи.х добавок к абсорбенту с целью у.меньшени  потерь, а также одновременио с осушкой и ОЧИСТКОЙ газа от сероорганических сосдипений, углезодородов Сз-Cg и HoS получать серу.Thus, the use of the proposed absorbent allows to increase the degree of gas drying, to eliminate the use of low-boiling additives to the absorbent to reduce losses, and also to dry and clean the gas from organic sulfur from Cs-Cg and HoS carbon. sulfur.
