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.
The flash calciner unit forms the heart of an entire calcination plant. As with our flash calciner, modular design is a defining feature of such a calcination plant. The plant set-up covers several stages leading up to calcination, including pre-drying, pulverising and a controlled feed system.
