To achieve maximum absorption efficiency inside a gas-liquid absorption column___________________?
Show answer Hide answer
Answer: C. Both gas as well as liquid streams should be distributed uniformly
Explanation
Uniform distribution of both gas and liquid streams prevents fluid channeling in absorption towers. Channeling bypasses active packing surfaces, reducing the effective interfacial area for mass transfer. Achieving maximum absorption efficiency requires complete and even contacting across the entire column. Absorption columns facilitate mass transfer between counter-current gas and liquid phases. Liquid distributors and gas inlets must be engineered to prevent localized fluid maldistribution. Packed towers depend on high interfacial contact area to achieve desired pollutant removal rates.
Industrial scrubbers use specialized spray nozzles to ensure uniform liquid coverage over packings. Gas absorption column design requires careful sizing of internal distribution trays to avoid bypassing. Environmental compliance relies on efficient gas liquid contact to meet strict emission standards. Distributing only the liquid phase leaves the gas stream prone to wall channeling effects. Distributing only the gas phase ignores liquid maldistribution and localized dry packing zones. Avoiding bypassing is a direct outcome of proper phase distribution rather than a separate method.
