Description

Известен состав дл  очистки газов, например ацетилена, от фосфина, содержащий. вес. %: Хлорид железа Сульфид меди 1,7 Окись ртути Карбонат натри  Вода Остальное Недостатком данного раствора  вл етс  в нем окиси токсичность из-за присутстви  ртути. Известен также состав дл  очистки газов, например ацетилена, от фосфина, содержащий хлорное железо, инфузорную землю, иодид кали  и воду при следующих соотношени х компонентов, вес. %: Хлорное железо27-28 Инфузорна  земл 49-50 Иодид кали 0,02-0,03 Вода 23,98-21,97 Однако такой состав имеет невысокую объемную скорость очистки газа (300 час-). большой удельный расход очистительной массы , невозмолма многократна  регенераци  очистительной массы. С целью устранени  указанных недостатков предложенный состав отличаетс  от известного тем, что он дополнительно содерл ит бромид лити  при следующем соотношении компонентов, вес. %: Хлорное железо27-30 Иодид кали 0,02-0,03 Инфузорна  земл 49-50 Бромид лити 7,5-8,5 ВодаОстальное Пример. Предлолсенный состав очищает ацетилен, содержащий 0,12 об. % фосфина с объемной скоростью 400 Удельный расход указанной смеси с учетом регенерации составл ет 250 г/м. Смесь молсно регенерировать 3 раза при контакте с воздухом в течение 20-24 час. В таблице приведены сравнительные данные известного и предложенного составов.A composition for cleaning gases, for example acetylene, from phosphine containing is known. weight. %: Ferric chloride Copper sulphide 1.7 Mercuric oxide Sodium carbonate Water Remains The disadvantage of this solution is its toxicity due to the presence of mercury. Also known is a composition for purifying gases, for example acetylene, from phosphine, containing ferric chloride, infusible earth, potassium iodide, and water in the following ratios of components, wt. %: Ferric chloride 27-28 Infusable earth 49-50 Potassium iodide 0.02-0.03 Water 23.98-21.97 However, this composition has a low volumetric gas cleaning rate (300 hours-). high specific consumption of the cleaning mass, non-resin repeated regeneration of the cleaning mass. In order to eliminate these drawbacks, the proposed composition differs from the known one in that it additionally contains lithium bromide in the following ratio of components, wt. %: Ferric chloride 27-30 Potassium iodide 0.02-0.03 Earth infusion 49-50 Lithium bromide 7.5-8.5 Water Remaining Example. The pre-composition cleans acetylene containing 0.12 vol. % phosphine with a volumetric rate of 400 The specific consumption of this mixture with regard to regeneration is 250 g / m. The mixture is molno regenerated 3 times upon contact with air for 20-24 hours. The table shows the comparative data of the known and proposed formulations.
