(d) To hold the gas

This question was posed to me in class test.

The origin of the question is Absorption Equipments topic in section Absorption of Food Processing Unit Operations

Answer 1

Correct answer is (c) To study hydrodynamic and absorption processes in packed columns

Easiest explanation: The gas absorption column is a scale unit. It is intended to study the hydrodynamic and the absorption processes in the packed columns. In this system, it absorbs CO2 and ammonia from an air mixture in a watery solution that move along the column.
