Abstract
AbstractIt has been demonstrated in this laboratory that specific organisms are capable of breaking both o/w and w/o petroleum derived emulsions. Specific bacteria have been selected and have been tested on model (kerosene/water) and on complex field emulsions obtained during enhanced oil recovery trials (w/o) and in tar sands extraction process (o/w).More recent studies involve the use of microbial biomass (sludge) from municipal and refinery waste water treatment processes as the de‐emulsifying agents for treatment of these emulsions.The results indicate that either pure microbial cultures or microbial waste biomass can be used to efficiently break industrial emulsions. This approach is a novel application and is a promising alternative to use of chemically synthesized industrial de‐emulsifying agents.
