A hydrocracking unit uses hydrogen under high pressure andheat to make motor fuels like gasoline. A reformer convertsrefining by-products into gasoline blending components. A sulfurrecovery unit extracts sulfur from hydrogen sulfide removed frommotor fuels in compliance with U.S. environmental rules. (Reporting by Erwin Seba; Editing by Richard Pullin)
