This heat can be used for electricity production. Power can be produced by using a steam cycle, an organic rankine cycle, or the KALINA process. The low temperature level of the waste heat in cement plants (200 – 400 °C) limits the efficiency to a maximum of 20 – 25%.
Cement clinker production contributes about 4% of global total CO2 emissions from fuel use and industrial activities. cement CO2 emissions . Facts from the International Energy Agency 2007 • The non-metallic mineral sub-sector accounts for about 9% of global industrial energy use, of which 70 to 80% is used in cement production.
downhole temperature during cement setting may significantly differ from the mud circulating or from the formation (undisturbed) temperatures. In this paper we suggest two methods (an empirical equation, the equivalent "API Wellbore" method).
