We could supply manytypes of FGD technology such as:

1. Lime(limestone)-FGD gypsum

 Maturetechnology, the largest stand-alone capacity of more than 1000mw

Desulfurizationefficiency> 95%

Availability of the system is stable> 98%

Desulfurizer - Limestone, cheap and easy to get

Desulfurization by-products - gypsum, can be profitable .

2. dual alkali FGD

2NaOH+SO₂=Na2SO₃+H₂O                 

Ca(OH)₂ + 2NaHSO₃=NaSO₃ + CaSO₃*1/2H₂O+1/2H₂O

NaSO₃+SO₂+H₂O=2NaHSO₃               

Ca(OH)₂ +Na₂SO₃+1/2O₂+2H₂O=2NaOH+CaSO₄*H₂O

Ca(OH)₂+NaSO₃=2NaOH+ CaSO₃

 Absorptionfast, reduce liquid to gas ratio, thereby reducing system operating costs

Serum sodium alkali is always circulation, reduce risk of fouling of systemoperation

Systemdesulfurization efficiency up to 98%

Alkaline solution recycling, improved sorbent utilization, lower system cost inoperating period

3. Ammonia FGD

The ammonia flue gasdesulfurization has many benefits, such as high-efficiency of desulfurization,low-energy consumption, steady operation, and without secondary pollution; atthe same time, its by-product, ammonium sulfate, satisfying the standard ofagrochemical, accompanying good market prospect.
