Description

Описываемый способ относитс  к сиособам получени  угольной кислоты из низкопроцентпых газов циклическим методом посредством применени  в качестве абсорбента раствора соды.The described method relates to methods for producing carbonic acid from low-percentage gases by the cyclic method by using soda solution as an absorbent.

При одинаковых услови х расхода пара содовые растворы должны примен тьс  с меньшим содержанием бикарбоната натри , растворы поташа (преврапдение карбоната в бнкарбонат происходит в пределах 50%). Благодар  низко; концентраини раствора бикарбоната натри  и тенденции последнего к пересыи.еиию, применение таких растворов в производственных услови х не встречает затрудненш н позвол ет проводить поглощение угольной кислоты 1,7-2.0 н растворами соды с превращением ее при этом в бнкарбонат натри  в предел .ах от 25 до 55%,.Under the same conditions of steam consumption, soda solutions should be applied with a lower content of sodium bicarbonate, solutions of potash (conversion of carbonate to bicarbonate occurs within 50%). Thanks low; the concentration of sodium bicarbonate solution and the tendency of the latter to transfer. The use of such solutions under production conditions does not meet the difficulty and allows the absorption of carbonic acid from 1.7-2.0 n soda solutions with its conversion into sodium bicarbonate in the limit from 25 to 55%.

При переработке низкопроцентных газов по обычно схеме последовательного включени  бащеи в снстеме резко возрастает сопротивление (примерно в 6 раз). Кроме того, должно быть резко увеличено количество перерабатываемых газов (примерно в 2,5 раза дл  газа , содержащего 9% угольной К слот1з1). Поэтому, в от обычных производственных схем, следует газовый поток направл ть по всем башн м параллельно.When processing low-percentage gases according to the usual sequential switching scheme, the resistance (about 6 times) increases sharply in the system. In addition, the amount of processed gases should be sharply increased (about 2.5 times for gas containing 9% coal K slot1). Therefore, in from the usual production schemes, the gas flow should be directed through all the towers m in parallel.

Как показали лабораторные опыты, на скорость абсорбции углекислоты благопри тно вли ет ус ленное орощен 1е. что позвол ет liaправл ть содовый раствор последовательно :. многократным возвратом его на каждую башню.As laboratory experiments have shown, the rate of absorption of carbon dioxide is favorably influenced by abundant oeschen 1e. which allows lia to direct the soda solution sequentially:. multiple return it to each tower.
