Abstract

Surfactant injection is one of the ways to lessen oil remains left in reservoir. This is done by injecting an active surface substance into reservoir until the tension of water-oil interface can be degraded. Reducing interfacial tension results in a reduced capillary pressure on pore stricture area of reservoir rocks until the oil caught in the pores can be pushed and produced.  In order to make this process function optimally, an appropriate surfactant that fits the condition and formation of water and reservoir is needed.  This study was conducted to get the best time of sulfonation process for producing MES surfactant with lower interfacial tension for EOR application at carbonate rock and to determine purification process of MES surfactant. Results showed that the best time of sulphonation to produce MES surfactant was from the third hour to the fourth hour.  The selected purification process was conducted without methanol addition.

Abstract

Biodiesel, a renewable fuel is normally produced from refine oil and methanol in the presence of a catalyst; conventionally it is used a basic homogeneous catalyst. However, when oil with high amount of free fatty acid (FFA) is used, this catalyst should not be used with the aim to avoid the production soap. In this work, FFA present in crude palm oil (CPO) were esterified with activated natural zeolite catalyst. The esterification reaction was carried out 60oC, with a  23.41 : 1 molar ratio of methanol to CPO, reaction time of 170 minute and catalyst amount of 1.59 %, conversion FFA of CPO was 64.23 %. In this work, biodiesel yield achieved was around 71.97 %.Biodiesel, a renewable fuel is normally produced from refine oil and methanol in the presence of a catalyst; conventionally it is used a basic homogeneous catalyst.

Abstract

The utilization of sago as a product which have higher value have not used maximally yet. Sago (Metroxylon spp.) is one of original plant from Indonesia which could be used as raw material for bioethanol. The objectives of the study were to analyze production of bioethanol with the variation of yeast Saccharomyces cereviceae concentration added (7%, 12%, 17%), fermentation time were (5 days and 7 days) and analysis of the financial feasibility industry from sago palm. The methods of the study analyze the financial feasibility by NPV, IRR, Net B/C, PBP, and sensitivity analysis. The result showed that fermentatiom time 7 days and yeast consentration 12% is the optimum tretments producted bioethanol from sago which result consentration 3,05% (v/v). The financial feasibility are Net Present Value is positive amounted Rp. 125 859 652 242, Internal Rate of Return of 17%, Net B/C ratio by 1,53, Payback Period for 6 years, and Sensitivity analysis showed that the 12% increase in raw material and 8% decrease in selling price, effect on the viability of the project. From the above considerations investment criteria, indicates that the business of bioethanol based on sago is feasible to run.
