Abstract

This study was aims to demonstrate that bagasse as a waste can be used for enhanced oil recovery process. Bagasse has sufficient lignin content to be processed into sodium lignosulfonate surfactant. The use of bagasse as raw material of surfactant for the chemical flooding is the development in the science of petroleum. Synthesized bagasse to lignosulfonate was done by isolation process using sodium hydroxide reagent and sulfonation process using sodium bisulfite reagent. From FTIR test and NMR test, sodium lignosulfonate (SLS) surfactant from bagasse consist of sulfonate groups (hydrphilic groups) and benzene (lipophilic groups). The synthesized SLS surfactant of bagasse has a HLB value of 11.62. The presence of hydrophilic and lipophilic components resulted in the stability of middle phase emulsion in the range of 5% - 10% and the core flood obtained recovery factor reaches 1.05% - 9.50%. With HLB value of SLS surfactant from bagasse indicated that it can be used as an injection fluid in the oil/water emulsion system, which is indicated by the presence of a middle-phase emulsion. Conclusion of this study indicate that the synthesized lignosulfonate of bagasse can use an injectin fluid in O/W emulsion and bind oil and water to form microemulsions. The bagasse is a local raw material for sodium lignosulfonate (SLS) surfactants which can be useful for enhanced oil recovery.
