IN SITU GENERATION OF POLYSULFIDE IONS USING ELEMENTAL SULFUR FOR IMPROVED CORROSION CONTROL,CYANIDE MANAGEMENT, MERCURY MANAGEMENT, ARSINE MANAGEMENT AND PERFORMANCE AND RELIABILITY OF ACID GAS REMOVAL EQUIPMENT

摘要

Methods and systems are provided for the in situ generation of polysulfide ions in a process stream including S2- and/or HS- ions. Methods and systems are also provided to ameliorate corrosion in a process stream containing an acid gas or a scrubbing agent solvent, and abate mercury and cyanide in process streams containing a scrubbing agent solvent.
