Abstract

A research about kinetic of crude oil solubility using biosurfactant from Brevundimonas diminuta and Pseudomonas citronellolis bacterias has been carried out. Sample was taken from abandon well at Babat Toman Musi Banyuasin. The order reaction and reaction rate constants of crude oil solubility was determined by using differensial method and integral method. The observation was carried out for 10 days, and integral method observation was carried out every 2 days, for 10 days. The initial TPH concentration (Total Petroleum Hydrocarbon) of sludge was obtained sequently which were 1.64%; 3.28%; 4.91%; 6.11% and 7.57% (w/w). after 10 days TPH concentration using B.diminuta bacteria decreased to 1.24%; 2.43%; 3.61%; 4.32%; 5.07% (w/w) and for TPH concentration using P.citronellolis decreased to 1.07%; 2.10%; 3.13%; 3.79%; 4.40% (w/w). The order reaction which determined by using differential method was 1.18 for B.diminuta and 1.1 for P.citronellolis. Further more, the order reaction was put in the integral equation thus forming reaction rate cosntants equation of crude oil solubility which is 0.018 day-1 for B.diminuta and 0.033 day-1 for P.citronellolis. Qualitative analysis which was carried out by using GC showed that biosurfactant from B.diminuta was able to dissolved hydrocarbon compound of crude at fraction with lower C atomic chain <C14 and C atomic longer >C22. Biosurfactant from P.citronellolis was able to dissolved hydrocarbon compound with atomic chain C10 – C14.
