Caustic recovery from a mercerising range is worthwhile because

  • A.effluent regulations forbid any discharge
  • B.the wash liquor carries recoverable alkali
  • C.caustic soda cannot be bought in bulk cheaply
  • D.the recovered caustic is stronger than fresh

Answer: B

Multiple effect evaporation concentrates the weak liquor back to working strength, and the economics are usually favourable. It also removes a large alkaline load from the effluent. Multiple effect evaporators are used for the duty.
