Pilot-Plant Technical Assessment of Wet Flue Gas ...

An experimental study was performed on a countercurrent pilot-scale packed scrubber for wet flue gas desulfurization (FGD). The flow rate of the treated flue gas was around 300 Nm3/h, so the pilot-plant capacity is one of the largest with respect to other published studies on a pilot-plant wet FGD. The tests were carried out at an SO2 inlet concentration of 2000 ppm by changing the recycle ...

Dry Flue Gas Desulfurization Technology Evaluation

The dry FGD process has the following disadvantages when compared to limestone wet FGD technology: 1. The largest absorber module used in the industry is 250 MW to300 MW. Some suppliers of dry FGD systems have proposed absorbers as large as 350 MW for eastern bituminous coal-fired units. For units sized at 500 MW, two modules will be required.

New Wet FGD Process Using Granular Limestone | Industrial ...

 · A new wet limestone−gypsum process for flue gas desulfurization (FGD) has been developed. The main difference compared to a conventional wet FGD process is the ability of the new process to utilize granular limestone directly as a desulfurizing reagent. Thus, the pulverizing of limestone, which causes power consumption, can be avoided. The performance of the wet FGD …
