Development of processes for production of methylertiarybutyl ether (MTBE) and tertiaryamylmethyl ether (TAME) gasoline blending components is described. Process operating costs and capital cost are both lower for MTBE production than for alkylation and the product has much higher octane. It is suggested that isobutylene can be better utilized in making MTBE than alkylate. The crux of refinery MTBE processine, i.e., integrating an MTBE process into a refining complex by removal of unreacted methanol, was studied. A process has been designed to make TAME such that the cost of octane-bbl appreciation is competitive with isomerization. There is a significant volume advantage in making both MTBE and TAME in a combined type oxygasoline process, rather than making MTBE alone. The ecnomics of both processes are favorable where octane-barrels are needed, and the economics will improve further where premium grades of unleaded gasoline are sold and with the expected reduction of methanol/olefin price ratio. The use of oxygasoline for octane appreciation can result in lower severity operation of reformers which in turn improves reformate yields.
