LIGHT CYCLE OIL (LCO)

Light Cycle Oil (LCO) is a diesel boiling range product from Fluid Catalytic Cracking Units (FCCUs). However, LCO is a poor diesel fuel blending component without further processing. Oil refining is an industrial process which involves separation, conversion and finishing. FCC centred refinery uses Fluid Catalytic Cracking Unit (FCCU) has the major conversion unit. FCCU is responsible for the production of petrol (gasoline), liquid petroleum gas (LPG), unsaturated olefin compounds, cracked gas oils, cycle oil, light gases and a solid coke residue. LCO may be processed further to break it down into more useful products; in particular it may be mixed with heavier products and put through the refining process again.
