Chemical Plant Absorption Tower

A: The terms are sometimes used interchangeably. An absorption tower generally emphasizes gas-liquid mass transfer, while a scrubber can refer more broadly to equipment used for gas cleaning, including particulate removal and gas absorption.

A: Depending on the absorbent and process design, towers can be used for selected H₂S, SO₂, HCl, NH₃, chlorine-containing gases and other soluble or chemically reactive gases.

A: Random or structured packing can be selected according to gas flow, liquid loading, pressure drop, fouling potential and mass-transfer requirements.

A: Yes. Stainless steel can be selected when the process medium requires improved corrosion resistance.

A: Yes, for suitable process conditions. Internal lining or coating may also be considered where required.

A: Yes, provided the materials, lining, internals and process design are selected for the specific corrosive environment.

A: Yes. Tower diameter, height, nozzle arrangement, support configuration and internal components can be customized.

A: Yes. Packed absorption towers can be manufactured with customized packing supports, distributors and demisters.

A: Yes, subject to the process design and required internal configuration.

A: Tower diameter is primarily related to gas flow rate, allowable gas velocity, hydraulic loading and the selected tower internals.

A: Tower height depends on the required mass-transfer performance, packing height or number of theoretical stages, gas-liquid equilibrium and process efficiency.

A: Material selection requires evaluation of the gas and liquid composition, concentration, temperature, pressure, pH and other corrosion factors.

A: Yes. Mesh-pad or vane-type mist eliminators can be integrated according to the required gas-liquid separation performance.
