Also known as:
Yeosu is a very large, medium complexity refinery located in South Korea.
It is owned and operated by GS-Caltex, a JV between Chevron and GS Group
Complexity: 7.6
Yeosu is a medium complexity plant, with resid hydrocracking and FCC as well as VGO hydrocracking and FCC. It also has asphalt and base oil capacity. However overall conversion is still small relative to its very high distillation capacity.

Atmospheric distillation - 785 kbpd - 4 units
Vacuum distillation - 150 kbpd
RCC - No 1 HOU project
Resid hydrocracker - No 4 HOU project
Hydrocracker - No 2 HOU project, Chevron Lummus (added in 2007)
FCC - No 3 HOU project
