LIQUIFIED PETROLEUM GASES
Liquefied petroleum gas (LPG) is the generic name for commercial propane and commercial butane. Petrojam supplies both grades to the domestic market. These are hydrocarbon products derived from the processing of crude oil. The process of light end fractionation splits the naphtha cut (from the crude oil) into propane and butane (LPG) for gasoline blending.
Commercial Propane predominantly consists of straight-chain hydrocarbons containing three carbon atoms; however propane (C3H8) is the main component. Commercial Butane predominantly consists of hydrocarbons containing four carbon atoms mainly n- and iso – butanes (C4H10). Both have the special property of becoming liquid at atmospheric temperature if moderately compressed, and reverting to gases when the pressure is sufficiently reduced. This liquid state is an advantage in transporting and storing these products. In the liquid state they are roughly 250 times as dense as they are when they are gases. Butane is usually supplied to customers in cylinders. Propane can be supplied in cylinders or in bulk for storage in tanks at the customers’ premises.
Individual LPG products have distinct uses. For example, propane is widely used as a fuel in the commercial and industrial sectors, while Butane is mainly used as cooking gas for residential users.
Kerosene falls within the light distillate range of refinery output that includes some diesel fuel, jet fuel, and other light fuel oils. The kerosene sidestream is hydrofined (treated with hydrogen over a catalyst to reduce sulphur and nitrogen content) and run down to tankage as dual purpose kero/turbo fuel.
Kerosene is used mainly as a cooking fuel and in lamps in Jamaica.
