- FGD application(power plant) -
The process
More than 90% of all desulfurization plants worldwide are using the wet desulfurization process, because of the absorber absorbents line and ammonia availability and the fact that the product of the wet process can be further utilized or easily disposed. The sulfur dioxide (SO₂) contained in the flue gas is absorbed chemically in an aqueous washing suspension of limestone (CaCO₃) quick lime (CaO) or slaked lime (Ca(OH)₂) and afterwards oxidized with atmospheric oxygen O₂ in a series of steps to produce gypsum (CaSO₄).
Oxidation Lance&Grid System
FGD Systems have evolved to Forced Oxidation with a Lance or grid designed to feed the proper amount of Oxidation Air into the Absorber Vessel and achieve the desired Mass Transfer. LUNRON has extensive experience in designing and supplying Gas Mixing System for Mass Transfer in many different markets and applications. Specifically for FGD.
Agitaion technology
Vertical (top entry) agitators are mainly use for suspending the solids during the preparation stage of limestone and for dewatering the gypsum. A number of horizontally mount (side entry) agitators are generally operate at the absorber tower.
Suspension
The side entry agitators installed around the absorber tower will maintain a complete and reliable off-bottom suspension. Any sedimentation inside the absorber sump formed by gypsum particles have to be avoid to achieve a continuous operation of the absorber tower without any interruptions. This will be achieved by optimal angular adjustments, both vertically(α) and laterally(β) plus strategic placement of the agitators around the absorber. Without the correct angle adjustment and too much distance between the agitators, sediments can occur in the center of the vessel or on the vessel wall which can lead to plugging of the pump nozzles. The ideal angle adjustment depends on the scale,Lunron mixers have the know-how to calculate and provide the right agitator set up for each absorber, to prevent the solids building up sediments and guarantee a reliable operation.
LUNRON has successfully applied hundreds of Top and Side Entry agitators for flue gas desulfurization processes, from the very first FGD installation in the 2006’s at the Ninghai power plants. At LUNRON, we bring 17 years of mixing experience to your flue gas desulfurization (FGD) process. We believe that getting the job done right means providing the degree of mixing you need while striking the best balance of capital cost, energy consumption, and reliability.
