Melaka PSR-2 Refinery

The brand new one hundred,000 bpd Melaka refinery generally known as PSR-2, is operated by the Malaysian Refining Corporation Sdn Bhd (MRC), a joint venture of Conoco (forty%), Petronas of Malaysia (45%) and Statoil (15%). The refinery uses Conoco’s proprietary delayed coking expertise to maximise manufacturing of diesel gas, which is in high demand in the region. In July 2001 Petronas acquired a further eight% fairness in MRC, bringing complete shares of MRC to fifty three%.

PSR-2 Course of Items

6 m diameter pressure vessel 500 cubic metersAlong with the hydrocracker, the project additionally required the construction of main PSR-2 course of models. These include a 62,000 barrels/day vacuum distillation unit, a 26,000 barrels/day catalytic reformer, a 35,000 barrels/day desulfurization unit and a 21,000 barrels/day delayed coker, which is able to utilise Conoco’s proprietary petroleum coking expertise.

The engineering, procurement, building and commissioning (EPCC) contract for PSR-2 was awarded to a four-firm consortium composed of Chiyoda Corporation, MMC Engineering Services, Chiyoda Malaysia and Mitsui & Co. LTD of Japan.

Conoco used its share of refined products from PSR-2, including LPG, a full range of gasolines, kerosene, jet-A1 and diesel, to supply the company’s current and deliberate advertising and marketing operations within the area.

On November 9th 1994, following an 18 month feasibility research, Conoco and Petronas, agreed to assemble and function the Melaka refinery.

In January 1999 completion of the development of a 28,500 barrels/day hydrocracker, meant that the crude oil refinery in Melaka, Malaysia was absolutely operational.


On July 1,1993, MRC appointed Foster Wheeler (Malaysia) Sdn Bhd as Project Administration Marketing consultant (PMC) for the PSR-2 Stage 1 Venture. Of the process models comprising the complicated, Foster Wheeler provided the design for crude distillation, vacuum distillation, saturated gas restoration, amine regeneration (2 trains), sour water therapy (2 trains), hydrogen assortment and distribution system, delayed coker light-ends, and a Foster Wheeler licensed hydrogen production unit.
