ABSTRACT:
In accordance with the method of this invention, sulfur is removed from the gas stream exiting a sulfur storage tank through condensation and impingement of droplets and/or particles of elemental sulfur on the baffles and wall(s) of indirectly cooled scrubber-condenser. In order to effect the melting and return to the liquid sulfur storage tank of any sulfur collected on the baffles and wall(s) of the scrubber-condenser, said baffles and wall(s) are periodically heated, preferably with indirect steam. The scrubber-condenser apparatus of this invention is designed to effect the condensation and solidification of sulfur from the gas stream and to maximize the impingement of sulfur droplets and particles upon its baffles and internal wall(s) by repeatedly changing the flow direction of said gas stream. The scrubber-condenser is vertically mounted on a liquid sulfur storage tank and is connected directly to a vent located on top of the tank.
