Refinery expansion brings more unleaded gasoline to Europe. Anon. Petroleum Review, May 1995, 49(580), 210--212.

Consideration is given to the way in which Petroleos de Portugal s.a. (Petrogal) is producing more high-value gasoline and jet fuel from each barrel of crude feedstock with a $650 million expansion of its refinery at Sines in Portugal. Safe alkylation has proved to be a key to profits, and the new gasoline complex, which is described, includes the Phillips Petroleum-designed hydrisom unit for selective diolefin hydrogenation, a defluorinator to remove fluorides from butane and propane, an HF stripper, a depropanizer, the vertical HF reactor/settler, fluidized catalytic cracking unit and feedstock heater using refinery fuel gas and acid-soluble oil for fuel.
