Benefits of technology

[0007]In one aspect, the invention is directed to a method for reducing the amount of hydrogen sulfide present in heavy oil and reducing the amount of corrosion in processing equipment contacting the heavy oil. The method includes the steps of adding an aqueous-based scavenger containing one or more aldehydes to 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. In one embodiment, the method further includes diverting

Problems solved by technology

Fossil products, and notably heavy oil, often contain significant quantities of hydrogen sulphide, H2S, which is a toxic, highly corrosive, inflammable and explosive gas.
The risk of exposure to hydrogen sulfide from handling heavy oil is a health and safety concern during stor

Abstract

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 glyoxal, to 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.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]This invention relates generally to processing heavy oil, and more particularly, to methods for removing hydrogen sulfide in heavy oil with an aqueous-based scavenger / oil emulsion.[0003]2. Description of Related Art[0004]Fossil products, and notably heavy oil, often contain significant quantities of hydrogen sulphide, H2S, which is a toxic, highly corrosive, inflammable and explosive gas. The risk of exposure to hydrogen sulfide from handling heavy oil is a health and safety concern during storage, transportation (shipping, truck or pipeline) and processing.[0005]Hydrogen sulfide scavengers can be used to remove hydrogen sulfide from heavy oil. It is known to be possible to reduce the hydrogen sulphide content present in aqueous mediums by using aqueous solutions of aldehydes such as formaldehyde, glyoxal, and glutaraldehyde (see for example the U.S. Pat. Nos. 4,680,127 and 5,284,635). However, simple addition of water-...
