Process intensification offers significant improvements in chemical manufacturing and processing, leading to cheaper, safer and sustainable technologies. Recovery of sulfur dioxide from gas emissions using an intensified process instead of the absorption by means of scrubbers is in the spotlight of many investigations. The substitution of the equipment by a membrane device intensifies the process from an environmental point of view, increasing process efficiency and reducing solvent losses, but the economic impact needs to be studied. This work considers a ceramic hollow fibre membrane contactor as membrane device and the modeling of mass transfer in the membrane contactor is performed in order to establish the influence of the operation conditions on the process efficiency and to carry out an environmental and cost evaluation-optimization study.
