sulphur dioxide produced by the combustion of sulphur in air is absorbed in water. pure so2 is then recovered from solution by stripping. make a preliminary design for the absorption column. the feed will be 5000 kg/h of gas containing 8% v/v so2. the gas will be cooled to 20c. a 95% recovery of sulphur dioxie is required. the solubility data is provided in the table below
