For process steam the efficiency ranges from 85%, 90% to 95%.
Efficiencies for thermal energy production are by definition 100% in relation to the corresponding energy carrier input. The thermal energy and process steam are produced at heat plants. Thermal energy, process steam: The thermal energy and process steam supply is modelled according to the individual country-specific situation with regard to emission standards and considered energy carriers. different crude oil production technologies or different flaring rates at the oil platforms. The different production and processing techniques (emissions and efficiencies) in the different energy producing countries are considered, e.g. Fourthly, the exploration, mining/production, processing and transport processes of the energy carrier supply chains are modelled according to the specific situation of each electricity producing country. element and energy content) are accounted for. Thirdly, the country-specific energy carrier supply (share of imports and / or domestic supply) including the country-specific energy carrier properties (e.g. Secondly, the national emission and efficiency standards of the power plants are modelled as well as the share of electricity plants and combined heat and power plants (CHP). due to pumped storage hydro power etc.), as well as imported electricity. Modelling the electricity consumption mix includes transmission / distribution losses and the own use by energy producers (own consumption of power plants and "other" own consumption e.g. Firstly, individual energy carrier specific power plants and plants for renewable energy sources are modelled according to the current national electricity grid mix. The country-specific modelling is achieved on multiple levels. Gypsum plaster board consists of gypsum (s Beta-Hemihydrate), and of cardboard cover, often based on recycled paper.Įlectricity: Electricity is modelled according to the individual country-specific situations. Transportation from the factory to the site is not included and must be added when analyzing life cycle systems. he system boundary is the finished product at the factory gate.
Gypsum also occurs in large quantities as the industry by-product. The anhydrous calcium sulphate can be found in nature as Anhydrit (CaSO4).
Natural gypsum stone is calcium sulphate-dihydrat (CaSO4*2H2O). Gypsum (chemical name Calcium sulphate) is available in different hydration levels, and in anhydrous form. Technology description including background system
