Prior to refining, the oil is pretreated to remove free fatty acids, phosphatides, and soaps. The conversion of Jatropha oil to biodiesel is a chemical reaction which takes place between the triglycerides which are the principal components of the oil and an alcohol such as methanol.

The resultant reaction, referred to as transesterification, produces methyl ester or biodiesel in an oil:diesel volume conversion ratio of 1:1. The reaction uses a catalyst (potassium hydroxide or sodium hydroxide) to initiate this esterification reaction; the catalyst promotes an increase in solubility to allow the reaction to proceed at a reasonable rate.

Excess of methanol from the biodiesel itself is evaporated under vacuum, condensed and pumped to the methanol storage tank for reuse.

The final polishing step removes impurities and water from the biodiesel in a process called dry washing.

The KIMMINIC system utilizes a proprietary hydrodynamic cavitation technology that facilitates a near instantaneous reaction along with reduced energy and methanol useage. The final biodiesel product meets European Biodiesel Standard EN14214:2008 and Ghana Standard GS 944:2008. Our Jatropha biodiesel is sold into local and international markets where it is being blended with fossil diesel and used as engine fuel in blend ratios varying from B2 to B100.
