· Over 70 per cent of the fuel requirement of cement manufacturers in India is met through petcoke. Cement manufacturing is an emission and energy intensive process and was responsible for 218 million tons of CO2 emissions in 2013 with close to 40 per cent of the emissions resulting from combustion of fuel to operate the kilns.
Stage of Cement Manufacture. There are six main stages of cement manufacturing process. Stage 1 Raw Material Extraction/Quarry. The raw cement ingredients needed for cement production are limestone (calcium), sand and clay (silicon, aluminum, iron), shale, fly ash, mill scale and bauxite. The ore rocks are quarried and crushed to smaller pieces of about 6 inches.
· In order select a suitable alternative fuel, a commercial modelling tool (ASPEN PLUS®) is used to model the four-stage pre-heater kiln system of a full-scale cement plant (clinker production ∼2900 tons/day), using petcoke as fuel. The goal is to optimise process control and alternative fuel consumption, while maintaining clinker product quality.
· The Indian Cement Industry today prefers petcoke as an alternate fuel for cement manufacturing for various reasons. The important among them are as follows: (a) High calorific value > 8,000 kcal/kg (3500-4500 kcal/kg conventional), low ash content and low volatile matter (but high sulphur content, up to 7%)
Purpose – Cement production has advanced greatly in the last few decades. The traditional fuels used in traditional kilns include coal, oil, petroleum coke, and natural gas.
· Cement Manufacturing Process Phase II: Proportioning, Blending & Grinding. The raw materials from quarry are now routed in plant laboratory where, they are analyzed and proper proportioning of limestone and clay are making possible before the beginning of grinding. Generally, limestone is 80% and remaining 20% is the clay.
INTRODUCTIONThe cement manufacturing process Cement manufacturing consists of raw meal grinding, blending, pre-calcining, clinker burning and cement grinding. In short, limestone and other materials containing calcium, silicon, aluminium and iron oxides are crushed and milled into a raw meal.
· Driven by increasing cement consumption, the global production of cement is projected to grow to over 5 billion tonnes worldwide by 2030 . This has a profound impact on the overall level of greenhouse gas emissions, as the production of each tonne of cement results in emissions of roughly 0. 9 tonnes of carbon dioxide (CO2).
