Improvements in and apparatus for the removal of foreign gases from the circulating gases of catalytic pressure reactions

摘要

PICT:0495129/III/1 Catalytic gas reactions are effected under pressure in a number of cycles connected in parallel, each cycle comprising a pump a, catalyst chamber b, cooler c, and separator d. Foreign gases are eliminated by washing with the liquefied reaction product in a tower g connected in parallel with the end cycle. Make-up gas is added at e to only a part of the cycles, at the opposite end of the system. The invention is applicable to such reactions as ammonia synthesis, destructive hydrogenation, and methanol synthesis.ALSO:Methanol synthesis is effected in a number of cycles connected in parallel, each cycle comprising a pump a, catalyst chamber b, cooler c, and separator d.
