Examples of Petrochemical Byproducts and Their Uses: Liquefied Petroleum Gas (LPG): Primarily composed of propane and butane, LPG is a versatile fuel used in heating, cooking, and as a transportation fuel. Naphtha: A highly versatile byproduct used as both a petrochemical feedstock (for plastics, synthetic rubber, and other chemicals) and a fuel. Light Diesel Oil: A byproduct that can be directly used as fuel in diesel engines, powering industrial machinery, generators, and transportation vehicles. Petroleum Coke: A solid byproduct with high energy content, used as a fuel in power plants and industrial furnaces. Refinery Gas (Tail Gas): A mixture of light hydrocarbons and hydrogen, often used as fuel within the refinery itself. Ethylene: A major petrochemical used to create polyethylene, a common plastic. Propylene: Another important petrochemical used to produce polypropylene, another widely used plastic. Benzene, Toluene, Xylene: These are aromatic feedstocks used in the production of various chemicals, including dyes, pesticides, and detergents. Butadiene: A raw material for synthetic rubbers.
