The calciner is used to heat the trona ore to around 300 – 350º F. Heating to this temperature drives off CO2 and some water to yield soda ash that can be further processed into a more pure form. Once trona ore has been processed, the now pure form of soda ash can be utilized in any number of processes to produce the products we rely on ...

Calcination in simple words can be described as a process of heating some solid material or a substance in a controlled environment. Usually in the process, the temperature is also regulated. Calcination is done to bring about some change in the substance physical or chemical constitution. During calcination, solids are heated at high temperatures.

Calcium looping (CaL), or the regenerative calcium cycle (RCC), is a second-generation carbon capture technology. It is the most developed form of carbonate looping, where a metal (M) is reversibly reacted between its carbonate form (MCO 3) and its oxide form (MO) to separate carbon dioxide from other gases coming from either power generation or an industrial plant.
