Filed:

Jul 30, 2008

Appl. No.:

12/182617

Inventors:

Sailendra Nemana - Naperville IL, US
Dan Coy - Naperville IL, US

Assignee:

BP Corporation North America Inc. - Warrenville IL

International Classification:

C10G 33/04

US Classification:

208188

Abstract:

This invention relates to compounds and methods for making and breaking emulsions of water and hydrocarbons with asphaltenes. The solutes of this invention include chaotropes and kosmotropes, which decrease or increase the order of water molecules respectively. Aggregated asphaltenes form a coalescing barrier at the oil-water interface to result in a stable emulsion and keep water droplets from uniting. Conversely, dispersed asphaltenes allow a coalescing interface at the oil-water interface to resolve the emulsion and allow water droplets to unite. Some applications of this invention include crude oil processing, refinery applications and water treatment methods.
