Intensification of processes in chemical industry

Separation processes in chemical engineering are mainly covered by distillation, extrac-tion and adsorption. Often these are energy-consuming processes and chemicals are needed for regeneration of adsorbents and extracting agents. Alternative membrane processes are more or less at the beginning. High potential is expected from combina-tion of membrane separation and chemical reaction in a membrane reactor.
