Process Description
Amerapex Corporation's process converts a triglyceride oil stream containing high free fatty acids into methyl esters utilizing an acid catalyzed esterification process with neutralization before the base-catalyzed transesterification process preventing unwanted soap formation. The acid catalyzed continuous esterification process takes place at low pressure while being aggressively mixed. The acid catalyst is neutralized or removed with the esters flowing to the glycerol separation, while the unreacted triglyceride oil flows to the transesterification step. This base catalyzed process step with the proper mole ratios of methanol containing a transesterification catalyst is used to convert over 98% of the triglyceride into methyl esters. After the transesterification process, the ester-glycerol stream flows to the glycerol separation step to separate glycerol from the ester product. The base catalyst is deactivated, and the excess methanol is recovered and recycled back to the transesterification reactor to minimize the fresh methanol makeup requirements. The methyl esters from the acid-catalyzed esterification process and the methyl esters from the base-catalyzed transesterification process are combined and purified to ASTM 6751 specifications for B-100 biodiesel.
