1. Introduction. Lime (CaO) is an important product used in different sectors of the industry as well as in agriculture. The production of lime is achieved through the calcination of limestone (mainly CaCO 3) at temperatures between 900 and 1200 °C.This process is highly endothermic and requires the combustion of fuels such as gas oil, …

Abstract. In this work a semi-physical model is developed for an industrial dry lime slaking process. The model is based on mass and heat balances for two non-stationary ideal stirred tank reactors in series. The mass balance equations are described by two partial differential equations. It is shown how the total reaction rate is derived from ...

The slaked lime produced by the reaction between quick lime and water. The main component of slaked lime is calcium hydroxide (Ca(OH) 2), and it is often applied as coating materials and tile adhesives. The industrial production line of lime The whole lime production line includes: mining, crushing, screening and calcinating.

The thermal treatment of limestone (mainly CaCO 3) to produce lime (CaO) is a major contributor to CO 2 emissions and the literature on decarbonising the lime industry is scarce. Subsequent hydration of lime would lead to the synthesis of slaked/hydrated lime Ca(OH) 2; the production of a tonne of Ca(OH) 2 emits ∼1.2 tonnes of CO 2 arising …

where the calcination process begins at around 820°C. Full calcination occurs at around 900°C. During the calcination process, the CaCO 3 is split into CaO (quicklime) and CO 2. These 'process emissions' are the reason lime production is considered an emissions intensive process. Quicklime (CaO) is produced in granulate, pebble or ultra-fine
