The invention pertains to a method of treating the distillation residue from the production of phosphorochloridothionates on a continuous or semi-continuous basis. The method comprises, agitating the residue with water to form a slurry which is storable, or pumpable at controlled rates to hydrolyzers for continuous or semi-continuous hydrolysis. The disclosed method, in addition to producing usable byproducts such as sulfur, phosphoric acid and hydrochloric acid also in contrast to prior art methods, significantly decreases fuel consumption and reduces the size and capacity of the facilities utilized to abate the emission of odorous gases to the atmosphere.
A method of treating distillation residue from the production of phosphorchloridothionates in a continuous or semi-continuous manner comprising introducing the residue into sufficient agitated water to form a pumpable and storeable slurry having a temperature below that necessary to cause decomposition of the residue and hydrolyzing the slurry in controllable amounts to decompose the residue and produce hydrolysis by-products comprising sulfur, phosphoric acid, and decomposition gases at controllable rates.
