A method of manufacture of Portland cement clinker is described in a dry process that captures the carbon dioxide emitted from the calcination of carbonate minerals, principally limestone. The process uses an indirectly heated, counterflow reactor to preheat and calcine the cement meal to produce a separate calcined meal and carbon dioxide gas stream, with external heat being provided by the ...
(a) Variation in process heat for cement production with coal consumption and (b) variable steam turbine isentropic efficiency with the size. Fig. 4 shows the influence of cement plant capacity (5000–9000 TPD) and steam pressure (12–48 bar) on power cycle thermal efficiency, net power output, plant EUF and steam generation capacity.
London coal gas production began in 1813 and by 1842 was producing 300,000 tons of coke a year, so coke was also readily available, and, being essentially a waste product, was cheaper than coal. Early cement plants used coal for drying slurry and for power generation, and coke for kiln burning. Per tonne of clinker produced, consumption was ...
