hat it is
Electric power is a fundamental necessity in all municipal and industrial endeavors. It is produced by power generation systems from primary energy sources such as uranium, fossil fuels (coal, oil or gas), as well as renewable sources such as water power, geothermal, wind and solar, biomass and municipal and industrial waste.
How it works
In the Oil & Gas industry and other industrial applications, power is generated by electric generators using, as prime movers, gas turbines, steam turbines, or reciprocating engines. Turbo-expanders are also used for power generation where a gas under pressure is expanded for process reasons, or made available for power recovery.
A gas turbine based power generation system may have several different configurations, from a simple cycle that provides no recovery of exhaust gas heat, to more sophisticated configurations that recover heat from the exhaust, thus enhancing the fuel efficiency of the overall system. Examples of the latter are cogeneration (CHP) systems featuring waste heat recovery boilers to produce steam or hot water for mechanical drive or heating purposes, and combined cycles that employ a waste heat boiler to produce superheated steam to drive a steam turbine. The combined cycle offers additional power generation capacity up to 50 percent more than that produced by the gas turbine alone. Hybrid systems including combined cycle and cogeneration are also common.
Stand alone steam turbine driven generator sets are used where steam is available from an industrial process, or when a boiler can be fed with low cost fuels from biomass or waste, in geothermal fields, and where steam is generated by solar energy.

What it is
Refineries convert the crude oil feedstock into commercial products by means of suitable distillation and chemical reactions, resulting in the production of a variety of valuable fuels and lubricants, as well as feedstocks for other downstream processes. Environmental regulations covering plant emissions and the composition of fuels drive plant upgrades and set new standards for grass root refineries.
How it works
The basic component of a refinery is the primary distillation (Topping) process where the crude oil is distilled into a number of fractions, from the lightest petroleum gases, to light and heavy naphtha, to the heaviest fractions up to asphalts and resid. The fractions coming from the topping unit are then treated in other processes for upgrading to commercially viable products; e.g., hydrodesulphurization and hydrotreating processes are used to produce fuels with reduced sulphur content, cracking processes are used to create a higher yield of lighter gasoil, kerosene and gasoline, the reforming process is used to increase the octane number of the gasoline, etc. The configuration of a refinery depends on the range of crude gravity that it is able to handle and on the final product mix it is designed for.
