Liquefied Petroleum Gas (typically referred to by its acronym – LPG) is a mixture of two main components Propane (C3H8) and Butane (C4H10). LPG has light density, high heating value and is mainly used internally as fuel gas in refinery. Moreover, LPG can be exported as commercial product if necessary.
LPG production process: LPG is mainly produced and recovered from top fraction of crude distillation column (refined in LPG recovery unit – LRU) and product of Residue Fluid Catalyst Cracking – RFCC (refined in Unsaturated Gas Concentration – USGC). It is also produced as by-product of Continuous Catalyst Reforming Unit (CCR). After that, LPG is stored in spherical tanks in liquefied form.
