Description

меньшее (50 л/ч) -на орошение второйкжерху .секции Эбсорбера.less (50 l / h) - for irrigation to the second head section of the Ebsorber.

Со браиный в емкость абсорбент из в:Т10|рой секции подают в -количестве 600 л/ч ка циркул цию ,в этой секции с помошью центробежного иасоса и в количестве 50 л/ч  а орошение Т1ретьей секции абсарберл.Absorbent from the tank collected in the tank: T10 | swarm section is fed in the amount of 600 l / h in circulation, in this section with the help of centrifugal pump and in the amount of 50 l / h and irrigation of the third section is absarberl.

Собранный в ниж ей части корпуса а-бсорбера абсорбент в количества 600 л/ч подают на .циркул цию в третью секцию, а 50 л/1ч направ  ют на регенерацию с целью извлечени  чистого ДМФ из раствора.The absorbent in the amount of 600 l / h collected in the lower part of the a-absorber body is fed to the third section for circulation, and 50 l / 1 h is sent for regeneration in order to remove the pure DMF from the solution.

В результате получено следующее распределение концент раций ДМФ в газе, проход шем а бсорбер, мг/им As a result, the following distribution of DMF concentrations in the gas passed through the adsorber, mg / im
