In a facility for the production of biodiesel using methanol as the transesterifying agent, the conversion of the reaction can be estimated using the following equation:

X 592:05613:1561ðmolar ratio met=oilÞ20:01925U60ðmolar ratio met=oilÞ

20:34ðmolar ratio met=oilÞ20:1459ðmolar ratio met=oilÞ2 Assuming that 96% of the methanol is recovered in the distillation column placed after the reactor (and recycling this amount), compute the methanol to be purchased and the methanol-to-oil ratio used if we aim for a conversion of 96% per pass.
