Abstract
A method of producing methanol is disclosed. The method involves adding alkali to crude methanol and distilling the crude methanol in one or more distillation columns. The method also includes flowing a vapor side draw from one of the distillation columns, where the vapor side draw comprises fusel oil substantially free from alkali. The fusel oil is recycled to a methanol synthesis reactor and/or a MTBE synthesis reactor.
