Process for the recovery of carbon disulfide |
| abstract |
Carbon disulphide recovery from viscose-process gas. Before scrubbing and purification stage, gas (mainly CS2) is sprayed separately with water (pref. 3000 1/30,000-40,000 m3 gas at 37 degrees C) and caustic alkali soln. (pref. 18000-20000 1 0.5-2.0 wt.% NaOH/30000-40000 m3 gas at 40 degrees C), giving aqs. NaHS soln. and gas (pref. containing 0.30.0.90 g.H2S/m3), from which CS2 is recovered by scrubbing, purification and adsorption. NaHS soln. obtained is pure enough for scouring viscose fibres before desulphurisation. At same time, CS2 recovery is economical. |
