Description Overview 105,000 bpd Commissioned in the 1970s and had a capacity of 155,000 bpd Now converted to an atmospheric/vacuum distillation refinery with FCC capabilities Designed to process light to heavy crude oils Can process crude oil with an API range of 19 to 44 (including Castilla, Hamaca, El Sharara, CPC, and Sahara blends) Nelson complexity index: 6.75 Processing Modes Low sulfur which maximizes production of road fuels High sulfur which focuses on producing commercial and off-road fuel Paraffinic which produces a high quality feedstock Bitumen/asphalt which focuses on producing road paving materials Key Units Crude distillation unit built in 1971, capacity of 21 kilotons per day FCC-2 catalytic cracker unit was built in 1970 for a different refinery and transferred to this one in 1987, capacity of 3.1 kilotons per day Hydrotreating and hydrodesulfurisation constructed in 1980, 4.2 / 4.5 kilotons per day Reformer and HDS-1 constructed in 1963, 2.4 and 1.9 kilotons per day
