Thai Oil PLC has let a $4-billion contract to a consortium of Saipem, Petrofac, and Samsung for the Clean Fuel Project at its 275,000-b/d refinery at Sriracha, Thailand (OGJ Online, Apr. 11, 2017).
The work will include engineering, procurement, construction and start-up for new units and upgrading of existing units.
The project includes retirement of two crude distillation units (CDU). The addition of a fourth, 220,000-b/d CDU to the third unit will raise the refinery’s total crude capacity to 400,000 b/d.
The project also will add a vacuum gas oil hydrocracker, a residue hydrocracker, a hydrogen manufacturing unit, a naphtha hudrotreater, a diesel hydrodesulfurization unit, a sulfur recovery unit, and an electric power plant fueled by residue pitch.
The refinery, now 100% dependent on light crude, will have a crude slate after completion of the project of 40-50% light crude, 5-15% medium crude, and 40-50% heavy crude after completion of the project.
The project will improve product yields to 25% light distillate, 62% middle distillate, and 13% others, such as sulfur, long residue, and reformate, with no fuel oil.
