A tons of mixed C4 + B tons of methanol = C tons of MTBE + D tons of ether, so what about C4?
Thread Content
Dear marine industry professionals, please help me figure out how to calculate the production efficiency of MTBE. For example, given a certain number of tons of mixed C4 and a certain number of tons of methanol, how many tons of MTBE can be produced, and how many tons of C4 will be left after that?
It mainly depends on the isobutylene content in the mixed C4.
Put it this way: 56 tons of isobutylene + 32 tons of methanol (slightly more in actual production) = 88 tons of MTBE. In the distillation process, the other inert C4 compounds besides isobutylene hardly react, so the amount of C4 remaining after etherification is essentially equal to the amount of these inert C4 compounds.
