Methods for recovering sodium sulfides from a sulfur scavenging reaction

摘要

A method is provided for the regeneration of a scavenging compound that has been reacted with hydrogen sulfide. Regeneration is accomplished through the use of calcium oxides and sodium hydroxide. Sodium sulfide is recovered from the regeneration process in a commercially useful form. Calcium oxides are also regenerated in the process, allowing for minimal or no chemical waste.
