چکیده مقاله:
Bioemulsifiers are a unique class of compounds that have been shown to have a variety of potential applications in the use of bacteria, in enhanced oil recovery and reduce oil viscosity. In this project, a bioemulsifier was synthesized by strain of Bacillus licheniformis and was separated by autoclave and centrifugal process; the purification of bioemulsifier and the increase quality of product was done by add sulfuric acid (H2SO4) (98%) to solution and centrifuged again. This bioemulsifier has the property of emulsification a wide range of heavy oils to form a stable oil-water emulsion. This bioemulsifier could reduce heavy oil viscosity of about 10000 cp to 250 cp for O/W emulsion. It is about 97% decreasing in heavy oil viscosity. the viscosity decrease measurements abide for a period of up to about 8 days.
