Abstract
Methyl tert-butyl ether (MTBE) is analyzed for economic efficiency in the stage of blending commercial automotive gasolines. Calculations were performed in applications to a hypothetical refinery with relatively mild crude oil processing, manufacturing unleaded AI-93 and A-76 gasoline in a 20:80 ratio. The composition of commercial automotive gasolines before and after the use of MTBE is shown and techno-economic indexes of automotive gasoline production in different processing schemes are given. The use of MTBE in combination with low-octane isomerizate may increase outputs of gasoline by 3.2%.
