Product Advantages

1. The gas and liquid films are impermeable, resulting in low pressure drop and allowing for high gas loads.

2. The falling film is very thin and generates unique surface ripples, with minimal backmixing between the gas and liquid phases, resulting in high heat and mass transfer efficiency and a large total fluid transfer volume per unit of energy consumption.

3. The descending liquid film can be cooled by indirect cooling, suitable for absorption processes with high heat effects, and allows the process to proceed at near-isothermal conditions.

4. Primarily used for HCl gas absorption to produce hydrochloric acid; also suitable for the absorption or separation of corrosive gases such as NH3, SO3, and H2S.

5. Features include low resistance, high absorption efficiency; flexible process conditions and wide production capacity adjustment range; no media pollution, high product quality; high heat transfer efficiency; long equipment life; and easy operation and maintenance.

Applications

Can be used for the absorption of hydrogen chloride gas in synthesis and recovery. Also suitable for the absorption of gases such as H2, S, SO2, and NH3, yielding a product concentration 5% higher than that obtained through adiabatic absorption. Using a two-stage series connection for cyclic absorption, efficiency can reach over 98%. Absorption Capacity: The absorber's production capacity can be adjusted within a wide range, making control convenient. For example, two 10m² membrane absorbers connected in series can produce 10-20 tons of 31% hydrochloric acid per day.
