lime, CaO, and produces lime mud, principally CaCO, as a by-product. The purpose of calcination is to convert the mud back into lime for reuse in the causticizing. The prime method used for calcination in the pulp industry is a rotary kiln. Conceptually,the lime kiln, which is a large cylindrical oven, can be divided into four process zones

Mar 24, 2021 The conversion is accomplished through calcination reaction at temperatures greater than 800 degree Celsius requiring large quantities of furnace oil. Hence, dry lime-mud going into lime-kiln would result in a decrease in furnace oil consumption. Moreover, variations in the quality of the re-burned lime can cause problems in the causticizing plant.

Apr 15, 2017 The main source of fossil emissions was the calcination of lime, which takes places in kilns at very high temperatures. In contrast, CO 2 uptake was the result of photosynthetic and carbonation processes: hemp absorbed CO 2 during its growth, while the binder started absorbing CO 2 after it got in contact with air during the mixing process.
