Process simulation and economical evaluation of an enzymatic biodiesel production plant has been carried out. Enzymatic biodiesel production from high quality rapeseed oil and methanol has been investigated for solvent free and cosolvent production processes. Several scenarios have been investigated with different production scales (8 and 200 mio. kg biodiesel/year) and enzyme price. The cosolvent production process is found to be most expensive and is not a viable choice, while the solvent free process is viable for the larger scale production of 200 mio. kg biodiesel/year with the current enzyme price. With the suggested enzyme price of the future, both the small and large scale solvent free production proved viable. The product price was estimated to be 0.73-1.49 euro/kg biodiesel with the current enzyme price and 0.05-0.75 euro/kg with the enzyme price of the future for solvent free process.
已对酶法生物柴油生产工厂进行了过程模拟和经济评估。已研究了从高质量菜籽油和甲醇生产无溶剂和共溶剂生产工艺的酶法生物柴油。根据不同的生产规模（8000 万和 2 亿公斤/年）和酶价格，研究了几种方案。发现共溶剂生产工艺最为昂贵，不是可行的选择，而无溶剂工艺在当前酶价格下，对于 2 亿公斤/年的大规模生产是可行的。按照未来建议的酶价格，小规模和大规模无溶剂生产都是可行的。当前酶价格下，无溶剂工艺的产品价格估计为 0.73-1.49 欧元/公斤生物柴油，未来酶价格下为 0.05-0.75 欧元/公斤。
