Abstract
Disclosed herein are gas conditioning systems and methods for treating hydrogen sulfide containing gas streams and, more particularly, disclosed are gas conditioning systems and methods with integrated flash gas recovery for reduced atmospheric emissions, including in one embodiment, conveying flash gases comprising flashed hydrocarbon gases and residual hydrogen sulfide from a flash drum to a suction drum.
Claims20
A system for treating hydrogen sulfide comprising:
- a source of hydrogen sulfide containing gas fluidically coupled to a suction drum;
- a compressor or blower fluidically coupled to the suction drum wherein the compressor or blower is configured to compress the hydrogen sulfide containing gas to form a compressed gas stream;
- an absorber vessel fluidically coupled to the compressed gas stream and a source of redox solution comprising a redox solution wherein the absorber vessel is configured to contact the compressed gas stream and the redox solution;
- and
- a flash drum fluidically coupled to the absorber vessel wherein the flash drum is configured to flash a bottoms stream from the absorber vessel to form a first overhead stream, wherein the first overhead stream is fluidically coupled to the suction drum.

A method for treating hydrogen sulfide comprising:
- introducing a hydrogen sulfide containing gas into a suction drum, wherein the hydrogen sulfide containing gas comprises hydrogen sulfide and hydrocarbon gases;
- conveying the hydrogen sulfide containing gas from the suction drum to an absorber vessel;
- contacting the hydrogen sulfide containing gas with a redox solution in the absorber vessel and reacting the hydrogen sulfide containing gas with the redox solution to form a bottoms stream comprising elemental sulfur, spent redox solution, and residual hydrogen sulfide;
- introducing the bottoms stream into a flash drum and flashing the bottoms stream to form an overhead stream comprising flashed hydrocarbon gases and the residual hydrogen sulfide;
- and
- conveying the overhead stream comprising the flashed hydrocarbon gases and residual hydrogen sulfide to the suction drum.
