Abstract
Recovery of an insoluble polymeric sulfur species from the reaction solution of a hydrogen sulfide conversion process is enhanced by adding a sulfur debonding agent to the hydrogen sulfide conversion reaction solution either at the outset of the process or after conversion of the hydrogen sulfide. Conversion of the hydrogen sulfide initially produces a soluble complex having the polymeric sulfur bound therein. The sulfur debonding agent breaks the soluble complex to produce a free insoluble polymeric species readily separable from the reaction solution by conventional physical means to obtain the desired sulfur product.
