Falling Film Absorbers
ANTICO FallFilm™ is engineered for high-efficiency gas absorption using a thin falling film of liquid on the inner surface of vertical tubes or plates, providing excellent heat and mass transfer simultaneously.
The working principle relies on liquid being distributed uniformly at the top of a vertical tube bundle and flowing downward as a thin film under gravity, while gas flows upward or downward in contact with the film. The system includes a tube-and-shell arrangement, liquid distributor head, gas inlet and outlet, and a sump for liquid collection. It is particularly suited for highly exothermic absorption reactions where simultaneous heat removal is critical. The thin liquid film ensures low liquid-side mass transfer resistance and fast gas absorption rates. The compact footprint and efficient heat removal make it ideal for applications such as HCl, HNO₃, and H₂SO₄ production. ANTICO FallFilm™ combines the functions of absorber and heat exchanger in one compact unit, reducing capital cost and plot area.
