An apparatus and process are described for the cooling and condensing of sulfur and water vapors from a Claus gas below the sulfur freezing point (248.degree. F.) at low pressure (&lt;30 psia), so that solid sulfur and condensed water are simultaneously removed from the Claus gas without solid sulfur plugging of the separation equipment and with efficient separation of the sulfur from water.

Water condenser/separator systems for Claus processes

A process is disclosed for stabilizing the viscosity of coal derived materials such as an SRC product by adding up to 5.0% by weight of a light volatile phenolic viscosity repressor. The viscosity will remain stabilized for a period of time of up to 4 months.
