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.
