Improvement of bagasse become lignosulfonate surfactant for oil industry

Abstract

The aim of this research is to use bagasse as a raw material as an effort to enhance the petroleum acquisition. There are two steps of processing bagasse into surfactant lignosulfonate which are the separation process of lignin from bagasse and the sulfonation process of lignin into lignosulfonate. The formation of surfactant lignosulfonate is a result of reaction between ion lignin with bisulfit. The sulfonate group/cluster at lignosulfonate are hydrophilic group which causes lignosulfonate to have amphipathic structure (surfactant). The comparison uses infrared test result against the formed component in surfactant sodium lignosulfonate from bagasse. With the two crude oil samples used in phase test, it turned out that at some light petroleum sample which were mixed with surfactant lignosulfonate formed a middle phase emulsion, with middle phase emulsion stability happening after the second day with a comparison of 10 - 50%. Meanwhile the heavy crude oil did not form a middle phase emulsion at all. Therefore, it can be concluded that bagasse has enough potential to be processed into surfactant lignosulfonate and to be used as injection fluid in the EOR process in oil industries.
