Key Data Set Information
Location HAIN-CN
Name
clinker production;clinker;new dry, 5000 t/d;fly ash
Use advice for data set When applying this data set, users should note that the functional unit is defined as 1 ton of cement clinker. The system boundaries are set from the extraction of raw materials from a mine in Hainan to the final production of clinker cement. Users should ensure that all relevant processes and energy inputs within these boundaries are included in the assessment. It is also pertinent to consider the environmental impacts of transporting raw materials and the use of fly ash. For complete life cycle assessment, downstream processes such as transportation of the clinker, cement making, and potential recycling scenarios should be incorporated separately.
Technical purpose of product or process The data set represents the conventional production of cement from clinker utilizing the new dry process at a capacity of 5,000 tons/day, with fly ash as one of the components. It is intended for use in the construction industry for creating various types of building materials where cement is a primary binding ingredient.

General comment m-CO2. The CO2 emissions of coal burning (mc) are calculated with the heat carbon equivalent method. mc=standard coal x 2.93x10^7x 8.494x10^-8 = standard coal x 2.489 where the CO2 of 1 J heat releasing is equivalent to 8.494 × 10^-8 kg. 1 kg of standard coal is equivalent to 2.93 × 10^7 J of heat (calorific value).

General comment n-CO2. The CO2 emissions of limestone decomposition (nc) are calculated with Eq. nc = Limestone consumption x 90% x 44% = Limestone consumption x 0.396 where the percent of CaCO3 in the limestone is 90% according to its quality. The percent of CO2 in the CaCO3 is 44%.
