🌐 Falling Film Absorber – High-Efficiency Gas Absorption Unit for Industrial Acid Recovery
🔍 Product Overview – Falling Film Absorber for HCl, HBr, NH₃, SO₂, Br₂ & More
The Falling Film Absorber is a high-performance gas absorption system designed to extract and recover gases such as Hydrogen Chloride (HCl), Hydrogen Bromide (HBr), Ammonia (NH₃), Sulfur Dioxide (SO₂), Hydrogen Sulfide (H₂S), and Bromine (Br₂). Built with borosilicate glass and PTFE contact parts, this system offers corrosion-free, high-efficiency, and compact absorption performance. It utilizes the principle of falling film technology for maximum heat and mass transfer efficiency with minimal pressure drop.
This absorber is ideal for applications requiring heat-sensitive gas absorption, efficient acid recovery, and high-purity results in industries such as chemicals, pharmaceuticals, and water treatment.
🔬 How Does It Work? – Step-by-Step Process of Falling Film Absorption
The Falling Film Absorber/ High Efficiency Acid Gas Absorber works on the co-current flow of gas and liquid downward in vertical tubes, where the absorbing liquid forms a thin film on the internal surface of each tube. This design promotes:
- Uniform Distribution: Both gas and absorbing liquid are uniformly distributed through a top-mounted distributor.
- Thin Film Formation: Liquid descends as a thin film, enhancing the surface contact and reaction efficiency.
- Simultaneous Cooling: Coolant circulates in the shell, removing the heat of absorption and maintaining low operating temperatures.
- Concentration Control: The absorbing liquid is recirculated through a tank until the desired product concentration is reached.
- High Throughput: The system allows higher linear velocity compared to conventional packed columns, reducing equipment footprint.

Efficient Heat Transfer
This is achieved in a Falling Film Absorber which is essentially a shell & tube heat exchanger in which both gas to be absorbed and absorbing liquid flow co-currently downward with extraction of heat by circulation of coolant in the shell. The abssorbing liquid is circulated through a tank till desired concentration is achieved. The liquid flows at such a rate that the tubes do not flow full of the liquid but instead, descends by gravity along the inner walls of the tubes as a thin film. Obviously, this produces a much greater linear velocity for a giver rate flow than could be obtained if the tube flowed full.
The equipment works as a number of water cooled-wall columns in parallel and each tube is provided with distribution system on top to effect uniform distribution of both liquid and gas and also formation of a thin liquid film on the inner surface of the tube.
SALIENT FEATURES
- The heat of absorption is continuously removed. This ensures better absorption and product concentration as compared with conventional packed tower
- Low residence time and operating temperature ideally suited to heat sensitive materials.
- Borosilicate glass and PTFE contact parts ensure corrosion/ contamination free operation
- Both standard and custom built units are available.
- Capable of operating from zero to maximum gas flow rate.
- Ease of installation due to light weight.
- Trouble free and consistent performance with minimal attention.
- Wide application e.g. HCl, HBr, NH , SO , H S, Br etc
- Less cost.
- Negligible pressure drop compared to conventional columns.
- Compact design Sleek and slender
- Both heat and mass transfer operations are incorporated in a single equipment.
- Very high heat transfer coefficient as the liquid falls instead of flowing.
- Scaling of process fluid is minimal due to high velocity and ease of cleaning by simple acid circulation.
