ABSTRACT:
Hydrogen sulfide is removed form a water stream comprising hydrogen sulfide and a high concentration of a Group IIA metal component such as magnesium and calcium components by maintaining the water stream at a specific acidic pH range and a specified temperature, and subjecting the resulting acidified hot water stream to vacuum flashing, in the absence of a stripping gas.
