Hot Gas Filter Market Has Potential to Grow By a Multiple Of 100
The market for filter elements which can withstand temperatures of 850oF has the potential to grow from just $30 million/yr now to over $3 billion/yr over the next decade. This is the conclusion reached by the McIlvaine Company in World Fabric Filter and Element Market.
Power, cement and waste-to-energy plants can benefit from a lower cost alternative for air pollution control while, at the same time, generating water rather than consuming it and greatly reducing energy consumption compared to alternatives. There are two options each with a different sorbent. Each will meet the most stringent standards for fine particulate, mercury, NOx, SO2, HCl, and VOCs.
