Abstract

1,200,550. Drying hydrogen and acetylene. WACKER-CHEMIE G.m.b.H. 25 Sept., 1968 [25 Sept., 1967], No. 45565/68. Heading B1L. Hydrogen or acetylene from vessel 1 is compressed in compressor 2, freed ifrom oil and water droplets in separators 3 and passed by line 8 to tower 4 maintained at 8-40‹C., preferably 10-30‹C., and filled with silica or alumina gel, dry gas leaving from the head. When exhausted, the desiccant is regenerated by passing the feed stream to heater 5 by line 12, and thence by line 10 back to tower 4 at 70-180‹C., preferably 70-160‹C., at a pressure from atmospheric to 0.5 atmospheres (gauge). The moisture-containing effluent is passed back to compressor 2 by line 11. In the drying phase, tower 4 is maintained at 8-25 atmospheres (gauge) for an acetylene feed, and up to 200 atmospheres (gauge) for a hydrogen feed. Jacket heater-cooler 9 is cooled with water during the drying phase and heated with steam during regeneration.
