Gas Inlet: Flow Capacity 100-10,000 m³/h

Component Specifications

Definition

A critical component in absorption column systems designed to introduce and distribute gas streams into the absorption tower. It ensures proper gas flow distribution, pressure regulation, and interface with upstream piping systems. The gas inlet typically includes connection flanges, flow control elements, and distribution mechanisms to optimize gas-liquid contact within the column.

Working Principle

The gas inlet operates by receiving pressurized gas from upstream processes and directing it into the absorption column through controlled openings. It maintains optimal flow velocity and distribution patterns to maximize surface area for gas-liquid interaction. Pressure differentials between the inlet and column interior drive the gas flow, while flow control elements regulate velocity and prevent backflow.

Materials

Stainless steel (316L, 304), carbon steel with corrosion-resistant coatings, Hastelloy, Inconel, or fiber-reinforced polymers depending on process conditions. Materials must withstand corrosive gases, temperatures up to 300°C, and pressures up to 10 bar.
