The coaltomethanol process can be divided into four major cost areas: coal purchase, coal gasification, gas preparation, and methanol synthesis. The contribution to the plantgate cost was estimated for each area except for coal purchase by dividing the plant capital and operating costs among the areas and calculating a product price for each.
