Abstract

The aim of the present study is to develop an efficient and cost-effective method for viscosity reduction of the heavy oil from the Liaohe oilfield by using mucopolysaccharide A as an emulsifier. The effects of varying the oil-water mass ratio, emulsifier concentration, emulsifying temperature, emulsifying agitation speed and emulsifying time on the emulsification and viscosity reduction were investigated. When a 6:4 mass ratio of oil to water and 150 mg/L dosage of emulsifier were shaken at 25℃ at 160 r/min for 6 h, the viscosity of the heavy oil decreased from 87000 mPa·s to 310 mPa·s, giving a viscosity reduction of 99.6%. In addition, the separated water containing the polysaccharide essentially maintained its emulsifying and degreasing effect for two batches, indicating its potential for reducing the cost of emulsifier production and demulsifying treatment. These results suggest that mucopolysaccharide A can be widely used in the mining and transportation of heavy oil.
