Air Pollution Control Technology Fact Sheet

Air Pollution Control Technology Fact Sheet

2015-9-1 · Wet limestone scrubbing has high capital and operati ng cost due to the handling of liquid reagent and waste. Nonetheless, it is the preferred process for coal-fired electric utility power plants burning coal due to the low cost of limestone and SO 2 control efficiencies from 90% up to 98% (Schnelle, 2002). Semi-Dry Systems

2019-5-26 · This process consists of 2 fluidized bed reactors connected by solid transportation lines. In one reactor (absorber), flue gas CO2 is captured by CaO at 873 K and the produced CaCO3 is transported to another reactor (regenerator), in which CaCO3 is decompd. to CaO at 1223 K. The produced CaO is transported to the absorber again.

2020-5-30 · The upflow velocity in UASB is an important design parameter as the process plays with the balance of sedimentation and upflow (SASSE 1998). On one hand, sludge should not be washed out the reactor, and on the other hand, a minimum speed needs to be maintained to keep the blanket in suspension, and also for mixing (TBW 2001b).An upflow velocity of 0.7 to 1 m/h must be maintained .
