Lime is a product derived from the thermal decomposition of limestone (mainly calcium carbonate, CaCO3) into quicklime (CaO) and carbon dioxide (CO2), also called calcination.

Acetylene production processes include the calcium carbide, hydrocarbon cracking, and methane partial oxidation methods, etc. (Kang et al., 2016).The calcium carbide method is a traditional and universally used acetylene production process; it is relatively simple, but is a large energy consumer and results in CO 2 emissions, which have a negative environmental effect …

Lime has been extensively used as an alkaline activator of pozzolana for binder formation. Yet, the calcination process for obtaining calcium oxide (CaO) has a high environmental impact due to high energy consumption and CO 2 production for converting CaCO 3 (limestone) to CaO (quicklime) [15].In order to address this problem, a number of …

This study aims to produce an eco-friendly white cement clinker by incorporation of celesto-barite mine waste. Samples of synthesized pure Monoclinic-C 3 S, Cubic-C 3 A and raw-mix were dried, ground to a Blaine of 3200cm 2 .g À1, doped separately with crescent amounts of mine waste and pure BaO (5 and 3% respectively), then burned at increasing temperature levels (1300 …

The production of lime and cement is responsible for around 8 % of global anthropogenic CO 2 emissions (Andrew, 2018).About 65 % of these emissions are associated with the calcination of limestone (IEA, 2020; Schorcht et al., 2013) and can only be avoided with carbon capture.There are many carbon capture technologies available —absorption, e.g., …
