EMULSIFICATION OF HYDROCARBON GAS OILS TO INCREASE EFFICACY OF WATER BASED HYDROGEN SULFIDE SCAVENGERS

摘要

A hydrogen sulfide scavenging process for heavy oil that reduces hydrogen sulfide while minimizing corrosion to processing equipment. The method includes the steps of adding an aqueous-based scavenger containing one or more aldehydes, such as giyoxal, Io the heavy oil using a static mixer injection system and creating an aqueous-based scavenger/heavy oil emulsion using a high shear/high velocity pump. The aqueous- based scavenger may be added in a scavenger addition branch, with the emulsion being formed in the addition branch and then returned to the processing equipment.
