Abstract
The disclosure relates to a process for the removal of solid CaS from a gas stream in which the CaS has been formed and then the conversion of that solid CaS by reaction with an aqueous NaOH solution to produce solid Ca(OH).sub.2 and a liquor stream containing dissolved NaHS. This removal and conversion process is described as being used in conjunction with a process for gasifying black liquor from a kraft pulping process in which H.sub.2 S is scrubbed from the gases using calcium compounds to form the CaS.
