    High temperature SO 2 capture during fluidised bed combustion One of the great benefits of fluidised bed combustion (FBC, 7 Chapter 2) is the option of in-situ SO 2 capture. The temperature level of ~ E C is such that CaSO 4 is a stable compound, and by adding a calcium-based sorbent to the fuel/bed material mixture the SO. This work has analyzed the influence of the particle size of a calcite from a quarry, whether original, calcined, or rehydrated, on the efficiency of CO2 capture of the gases emitted in a coal-fired power plant. Three different particle sizes mm, mm, and mm have been studied. The calcination had a minimal effect on the particle size of the smaller samples A Cited by: 1.

Program Element No. EHEA EPA Project. Sulphur capture by calcium-based sorbents is a process highly dependent on the temperature and CO 2 concentration. In oxy-fuel combustion in fluidised beds (FB), CO 2 concentration in the flue gas may be enriched up to 95%. Under so high CO 2 concentration, different from that in conventional coal combustion with air, the calcination and sulphation behaviour of the sorbent Cited by: Reactivation by Steam Hydration of Sorbents for Fluidized Bed Calcium Looping Article in Energy & Fuels 29(7) June with Reads How we measure 'reads'.

In industrial processes, such as fluidized bed combustion, calcium-based sorbents are always injected into the high temperature combustion furnace to capture the acidic gas, such as SO 2 and HCl.

The cycled modified limestone shows a greater SO 2 retention than the cycled raw one after the same prolonged carbonation treatment. The prolonged carbonation increases the pores in 5–20 nm range which is considered the optimum pore size for sulfation of CaO-based sorbent, so it results in an improvement in SO 2 retention of the cycled by: 6.
