In today’s growing oil tension, biodiesel can be used as the alternative for fossil fuels, with broad prospect. The raw materials for manufacturing biodiesel- vegetable oil can be recycled on the one hand, and the use of biodiesel is more environmental- friendly. on the other hand, our company can undertake 5-2000TPD biodiesel machine project, including engineering design, equipment manufacturing technical services, product research and development etc.
Biodiesel is produced by raw materials of refining vegetable oil or acid oil transformed from refined offcuts of oil plant(soap stock, oil foot, deodorized extract, waste bleaching clay etc.) the price of acid oil is about 1/3 of vegetable oil, so the production of biodiesel with acid oil or fatty acids as raw materials has more advantages than the use of vegetable oil. it not only has the price advantage, but also eliminates the problem os environmental pollution of refinery, thereby achieving double benefits.
