Ishak S., Hashim H., Muis Z., 2015, Optimal Low Carbon Cement Production Cost via Co-Processing and Carbon Capture and Storage, Chemical Engineering Transactions, 45, 295-300.
Cement production is recorded to have released about 5 % of current global man-made CO2 emissions. They came from the burning of fossil fuel in kiln, electricity usage from grinding of raw and finished materials, and from the calcination of main raw material; limestone to produce clinker. This paper objective is to find the best minimized solution of cement production cost while reducing CO2 emission and without compromising the quality of cement product. This is achieved by developing mathematical optimisation model that will be executed using General Algebraic Modelling System (GAMS). Some of data used in this research will be costs to install the technologies, costs of raw materials and fuels, properties of raw materials, CO2 emission improvements from CO2 reduction technologies and others. CO2 reduction technologies for cement industry considered in this study are co-firing (co-process) and carbon capture and storage. This paper also discusses the best combination of energy efficient technologies to meet the CO2 reduction target and product specification.
