Limestone scrubbing - Glossary of Meteorology

2012-1-26  limestone scrubbing A system for removal of SO 2 from pollution sources by injecting calcined limestone into the exhaust gas system. In a wet scrubber (the most common type), the absorbent, a mixture of water and limestone, is sprayed inside a treatment area onto the flue gas , which rises from the bottom of the absorber area.

Dry Scrubber - an overview ScienceDirect Topics

A circulating fluidized bed (CFB) involves a scrubbing technology known as a dry scrubber process. In this process, hydrated lime, limestone, or dolomite and water are intimately mixed with flue gas in a dedicated reaction chamber, which is the fuel-firing bed. Reacted solids get dried completely by the sensible heat of the flue gas.

The lime/limestone scrubbing process is the most commonly used method for reduction of the SO2 concentration in flue gases. The process requires a large amount of energy for slurry recycling in the scrubber and therefore careful control of the ratio between slurry and gas flow rate is required. Calculation of the minimum ratio of slurry to gas flow rate (L/V) m under equilibrium conditions, in ...

2021-9-22  Flue-gas scrubbing Flue-gas scrubbing is a process for removing oxides of sulfur and nitrogen from the waste gases emitted by various industrial processes. Since the oxides of sulfur and nitrogen have been implicated in a number of health and environmental problems, controlling them is an important issue. The basic principle of scrubbing is that flue gases are forced through a system of ...
