Resist HF. Extend Service Life.
The Latest Developed Carbon Fiber Filter provides a best solution for smelter plant, such as copper, zinc, lead, pyrite and other non-ferrous smelter and chemical industries with HF present.
For the sulfuric acid plant in smelter, glass fibre candle filters are mostly used in absorption towers. However, the ore grade, chemicals are usually various from each smelter. For some smelters, the off-gas contains high fluorine due to the ore. HF present will cause corrosion of glass fiber and reduce life of candle filter. It has been a very headache problem for some smelters.
Carbon Fibre Candle Filter provide longer life and high efficiency for gas emission control for off-gas acid plant with HF present. It is the HF solving expert.
