Biogas - Wikipedia

Biogas is the mixture of gases produced by the breakdown of organic matter in the absence of oxygen (anaerobically), primarily consisting of methane and carbon dioxide. Biogas can be produced from raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste or food waste.Biogas is a renewable energy source.. Biogas is produced by anaerobic digestion

Damage Mechanisms affecting Oil and Gas industry

Damage Mechanisms (also referred to as degradation mechanisms) is a general term referring to any cause of problems or failures within process equipment. These can range from corrosion, to cracking, to heat damage, and everything in between. When assessing damage mechanisms, one must take into account the current state of the equipment, as well as any potential damage the mechanism may

Integrated Coal Gasification Combined Cycle (IGCC) Power

The air-blown gasifier causes a reaction between the supplied coal with a gasification agent to generate high temperature combustible gas mainly composed of carbon monoxide (CO) and hydrogen (H 2).. The gasifier has a two-chamber two-stage structure, consisting of a combustor at the lower (first) stage and a reductor at the upper (second) stage.

Gasification-derived syngas differs from natural gas in terms of calorific value, gas composition, flammability characteristics, and contaminants. An oxygen-blown, entrained-flow IGCC plant will typically produce syngas with a heating value ranging from 250 to 400 Btu/ft 3 (HHV basis), which is considerably lower than the 1000 Btu/ft 3 for

Steam Rankine Cycle - an overview | ScienceDirect Topics

Steam Rankine cycle is known as one of the main power-generating cycles, which consists of four key devices, namely a boiler (heat exchanger), a steam turbine, a condenser (heat exchanger), and a pump, as illustrated in Fig. 28.This cycle needs heat input for the boiler either by burning fossil fuels, such as oil, coal, and natural gas, or by obtaining the necessary heat from renewable energy

Coal - Wikipedia

Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.
