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.

Sulfur debonding agent enhancing sulfur recovery from a hydrogen sulfide

A method and apparatus for studying the conditions under which multiple condensed phases form during production, transportation, and processing of crude oil and other organic liquids. The sample temperature and pressure are controlled, and changes in fluorescence and/or electrical conductance or conductivity occurring within the sample due to formation of multiple condensed phases are detected. The measurements are made using a cell containing the liquid sample at elevated temperature and pressure. The cell has a generally cylindrical housing and separate means for visually inspecting a liquid sample which is present within the cell, controlling the temperature of the liquid sample, controlling the pressure of the liquid sample, detecting fluorescence changes occurring within the sample, and determining the electrical conductivity of the sample.
