Petroleum Coke is defined as a black solid residue obtained by cracking and carbonising of petroleum derived feedstocks, vacuum bottoms, tar & pitches in processes such as delayed coking or fluid coking. Petroleum coke is a by-product of the oil refining process. Petroleum coke is a carbonaceous solid derived from oil refinery coker units or other cracking processes. Petroleum coke used in the production of electrodes for the steel and aluminum industries. Petroleum coke is high in sulphur and low in volatile content, which pose some environmental and technical problems with the combustion. Petroleum coke is used as either a primary or a secondary fuel in a new grassroots plant or for co-firing in an existing coal-fired power plant. Petroleum coke is a solid, hard, black residue material that remains after heavy residual oil fractions are cracked to produce lighter hydrocarbons. Petroleum coke is used in the cement, lime, power generation and aluminum industries.

Petroleum coke is a carbonaceous solid derived from oil refinery coker. There are several types of petroleum coke produced depending upon the process used, operating conditions, and feedstock properties. It contains some high-molecular-weight hydrocarbons left from incomplete carbonization reactions. These incompletely carbonized molecules are referred to as volatile materials in the coke. Fuel grade cokes are sold as green coke. The main uses of petroleum coke include fuel, manufacture of anodes for electrolytic cell reduction of alumina, direct use as chemical carbon source for manufacture of elemental phosphorus, calcium carbide, & silicon carbide and manufacture of graphite.

Petroleum engineering is engaged in the exploration and production activities of petroleum as an upstream end of the energy sector. It covers a wide range of topics, including geology, geochemistry, geomechanics, geophysics, oil drilling, geopolitics, seismology, tectonics, thermodynamics, well logging, well completion, oil and gas production, reservoir development, and pipelines.

Petroleum jelly is a a semi-solid mixture of hydrocarbons. It is a purified mixture of semi-solid, saturated hydrocarbons, mainly of paraffin nature, obtained from petroleum. It may contain antioxidants approved for food use. It is originally promoted as a topical ointment for its healing properties. Its folkloric medicinal value as a cure-all has since been limited by better scientific understanding of appropriate and inappropriate uses.

Petroleum oil fortifier is a composite of super-concentrated additives that dramatically increase the effectiveness and durability of lubricants in automotive and industrial applications. It is used in combination with lubricating fluids and significantly reduces friction, harmful deposits, corrosion and parts wear resulting in the extension of equipment and lubricant life in addition to improved operating efficiency and power.

Petroleum processing service is provided for the separation of petroleum into fractions and the treating of these3 fractions to yield marketable products. Petroleum is a mixture of gaseous, liquid, and solid hydrocarbon compounds that occurs in sedimentary rock deposits. Petroleum processing involves a series of steps by which the original crude oil is converted into products with desired qualities in the amounts dictated by the market.

Petroleum refineries utilize a vast array of chemical processes to convert raw material and crude oil into a variety of products. These products include fuels, petrochemical feedstocks, solvents, process oils, lubricants, and specialty products such as wax, asphalt, and coke. With the use of a maze of pipes, distillation columns, and chemical reactors, these refineries turn crude oil into valuable products.
