Title: Dennis Dalrymple: Innovator in Gas Stream Treatment
Introduction
Dennis Dalrymple is a notable inventor based in Georgetown, TX (US). He has made significant contributions to the field of gas stream treatment, particularly in the removal of hydrogen sulfide. With a total of 2 patents to his name, Dalrymple's work focuses on innovative processes that enhance environmental safety and efficiency.
Latest Patents
Dalrymple's latest patents include a process for removing hydrogen sulfide from gas streams that are supplemented with sulfur dioxide. This process involves scrubbing with a nonaqueous sorbent, where the gaseous stream is contacted with a sorbing liquor containing a nonaqueous solvent and a tertiary amine base. The reaction between the sorbed hydrogen sulfide and dissolved sulfur forms a nonvolatile polysulfide, which is then converted back to sulfur through oxidation. This innovative approach not only improves hydrogen sulfide removal but also minimizes chemical degradation and byproduct formation.
Another patent focuses on a similar process, utilizing a non-aqueous scrubbing liquor that can be an organic solvent for elemental sulfur. By adding sulfur dioxide to the sulfur-amine nonaqueous sorbent, the efficiency of hydrogen sulfide removal is enhanced, leading to lower rates of byproduct formation.
