Chevron Press Release - Chevron Technology Selected For Japan Refinery Upgrade

SAN FRANCISCO, June 24, 1994 -- Chevron International Oil Company announced that it has been selected by Japan's Tohoku Oil Company, Ltd. to provide technology for building a new residuum desulfurization (RDS) unit at Tohoku's 100,000 barrel-a-day Sendai Refinery.

Terms of the agreement were not disclosed.

In order to meet Japan's growing demand for transportation fuels, Tohoku must increase its capacity to upgrade residuum, an asphalt-like material left over after lighter petroleum fractions have been distilled from crude oil. Tohoku selected Chevron's RDS Hydrotreating technology as the residuum feed pretreater for the Sendai Refinery's existing residuum fluid catalytic cracking (RFCC) unit.

Chevron's technology was selected for the planned 45,000-barrel-a-day unit due to the company's recent improvements in catalytic residuum processes and Chevron's extensive experience in designing RDS units. More than 40 percent of the RDS units operating at refineries worldwide are of Chevron design.

Tohoku Oil Company is a subsidiary of Mitsubishi Oil Company. The Sendai Refinery is located about 230 miles north of Tokyo.

Chevron International Oil Company, a Chevron Corporation subsidiary, licenses refining process technologies worldwide. It also markets catalysts, lubricants, marine fuels and aviation fluids; and trades crude oil, refined products and liquefied natural gas internationally.
