The treated gas is introduced from the gas inlet at the bottom of the main body, passes through the filling layer of HiLex, and is discharged from the gas outlet at the top. Meanwhile, the absorbent liquid is sprayed from the top of the filling layer and comes into countercurrent contact with the treated gas. During this process, the target substances in the gas diffuse and dissolve into the liquid phase. 【Features】 ■ Efficient removal: High-performance packing material HiLex selected according to design conditions ■ Low pressure loss, low power costs: ■ Compact design: ■ Compatible with various applications: Designed for use not only in absorption towers but also in dispersion towers, dehumidification towers, recovery towers, mist and dust removal towers, and gas cooling towers. *For more details, please contact us or download the catalog to view.
