This is a base-load unit with a maximum continuous net generating capacity of 115 MW. A typical process flow diagram of a conventional wet scrubber including gas handling and SO2 absorption is shown in Figure 1. In wet scrubbers, the flue gas enters a large vessel (spray tower or absorber), where it is sprayed with a water limestone slurry. The calcium in the slurry reacts with the SO2 to form calcium sulfite.

Jul 01, 2017 1. Introduction. Flue gas desulfurization (FGD) involves the removal of sulphur dioxide (SO 2) contained in gases produced by the combustion of fossil fuels such as coal, oil, municipal solid waste and many industrial processes.SO 2 emissions are a primary contributor to acid rain and have been regulated by every industrialized nation in the world (Crdoba, 2015, Dou et al., 2009). Sep 19, 2007 The wet flue-gas desulfurization equipment according to claim 1, wherein a trough, by which the absorbent slurry that flows down along an inner wall surface of the absorbing tower is prevented from flowing into an opening at the front end of the gas entrance flue, is disposed at a portion above the opening at the front end of the gas entrance flue.

The wet limestone - gypsum flue gas desulfurization consists of three subsystems, which are subsystem of flue gas treatment and sulfur dioxide absorption, subsystem of gypsum dehydration and subsystem of reaction agent preparation, respectively. Schematic diagram of the process flow chart is shown in Fig. 1. The wet flue gas Scope and Content FGD systems are generally the last pieces of equipment to handle the boiler flue gas before it reaches the stack. In lime/limestone slurry processes, S02 in the flue gas stream is removed with the aid of dilute limestone or lime slurries. The treated flue gas is cooled and satu- rated with moisture in the process.
