Description
Изобретение относитс к способам очистки газов от аммиака, широко примен емым в химической промышленности.The invention relates to ammonia gas purification methods that are widely used in the chemical industry.
Известно несколько абсорбционны.х способов очистки газов от аммиака. Наиболее распространенным из них вл етс способ, где абсорбентом вл етс вода.There are several absorption methods for purifying gases from ammonia. The most common of these is the method where the absorbent is water.
Недостатком этого способа абсорбционной очистки вл етс неполна очистка газов от аммиака.The disadvantage of this method of absorption purification is the incomplete purification of gases from ammonia.
С целью устранени этого недостатка предложено .примен ть в качестве адсорбентов аммиака силикагели марок КСМ, КСК, алюмогели , .катализаторы марок 482, 481-10 и алюмосиликатный .In order to eliminate this drawback, it was proposed to use silica gels KSM, KSK, aluminum gels, catalysts 482, 481-10 and aluminosilicate as adsorbents of ammonia.
Наилучша очистка легких газов от аммиака достигаетс :пр,и .применении в качестве адсорбента силикагел марки КСМ.The best purification of light gases from ammonia is achieved: pr, and the use of silica gel KSM as an adsorbent.
Нроцесс адсорбции осуществл етс в адсорбере при температуре не более 30° С, объемной скорости до 1500 , давлении и влажности в зависимости от технологического процесса.The adsorption process is carried out in an adsorber at a temperature not exceeding 30 ° C, a space velocity up to 1500, pressure and humidity, depending on the technological process.
При м 6 р. Объем загруженного силикагел кем 140 слз, высота сло адсорбента 19 см. При температуре 18-22° С, давлении 1 ата, объемной скорости 1000 , линейной скорости 0,0478 м/сек, влажности 50-60% максимальна емкость по аммиаку силикагел марки кем с насыпным весом 0,769 г/смз составл ет 13,8 мг/г силикагел , продолжигельность цикла адсорбции 900 час.At m 6 r. The volume of silica gel loaded is 140 slz, the height of the adsorbent layer is 19 cm. At a temperature of 18-22 ° C, a pressure of 1 atm, a space velocity of 1000, a linear speed of 0.0478 m / s, a humidity of 50-60%, the maximum capacity for ammonia is silica gel with a bulk weight of 0.769 g / cm 3, is 13.8 mg / g silica gel; the duration of the adsorption cycle is 900 hours.
В течение 81 час в газе после очистки наблюдаетс Полное отсутствие аммиака.For 81 hours in gas after purification, a complete absence of ammonia is observed.
Предмет изобретени Subject invention
Способ очистки газа от аммиака путем сорбции , отличающийс тем, что, с целью повышени степени очистки, в качестве сорбента используют силикагель и процесс сорбции осуществл ют .при тем.пературе не выше 30° С и объемной скорости 1000-1500 .The method of gas purification from ammonia by sorption, characterized in that, in order to increase the degree of purification, silica gel is used as a sorbent and the sorption process is carried out at a temperature not higher than 30 ° C and a bulk velocity of 1000-1500.
