Combined enthalpy
WebThis video is an excerpt from a series of peer exchanges hosted by the Advanced Manufacturing Office and the Better Buildings Better Plants Low Carbon Pilot. Take a deeper look at understanding how combined heat and power can increase energy efficiency, play a role of decarbonization, and learn about the DOE’s CHP deployment … Many process industries, such as chemical plants, oil refineries and pulp and paper mills, require large amounts of process heat for such operations as chemical reactors, distillation columns, steam driers and other uses. This heat, which is usually used in the form of steam, can be generated at the typically low pressures used in heating, or can be generated at much higher pressure and …
