An absorption and desorption rig has been built at Telemark University College. The absorption column has a structured packing height of 1500 mm, a total height of 2500 mm and an inner diameter of 100 mm. The desorption column has a random packing height of 1000 mm and a total height (including a reboiler and a condenser) of 3000 mm. The rig also contains a rich/lean heat exchanger, a solvent cooler and two pumps. The purpose of the rig is to perform measurements of CO₂ removal efficiency and energy consumption at different temperatures, flows and CO₂ concentrations. Different solvents like carbonate solutions and amine mixtures can be studied. The CO₂ absorption rig has been used successfully to measure the absorption efficiency as a function of different parameters at stable conditions. The measurements can be used to validate process calculations and to find optimum process conditions.
