High-efficiency NO(x) absorption in water using equipment packed with a glass fiber filter.

NO(X) absorption in water is quite difficult by comparison with other exhausted gas, such as SO(2), CO(2), and NH(3) because of low solubility of NO(X) in water. We have been developed a NO(X) absorption equipment with a glass fiber filter having high porosity and surface area. When feed NO(X) gas concentration was high, high NO(X) removal efficiency was obtained.
