침대태주석화공사갑을동장치미기적조성특점，채용전냉각、흡부류정회수기중적경기。통과냉각탈제미기중협대적액체화부분고탄순；채용삼탑흡부조작，재상온하탈제미기중갑을동、중정순급C4조분，고온하사흡부제재생。장치표정결과표명，경기적체적분수체도99．99％，회수솔고체93．75％。
According to the composition of tail gas in methyl ethyl ketone device, hydrogen was recovered by cooling process before absorption recovery. Liquid and part of higher alcohols v/ere removed from tail - gas in cooling system, methyl ethyl ketone, see - butyl alcohol and C4 components were removed with three absorption towers at room temperature, while adsorbent was regenerated at high temperature. The volume fraction and recovery rate of product hydrogen reached 99. 99% and 93.75%, respectively.
