1. Membrane Technology KNM's BORSIG membrane-based separation processes are state-of-the-art today and in some areas this technology has become the leading process solution. This was made possible by the development of efficient and selective polymer membranes which ensure the thermal, chemical and mechanical stability necessary for industrial use. Integrating the membranes into suitable module designs ensures reliable and safe operation. Membranes are used in many applications in the chemical, petrochemical and oil/gas industries where liquid or gaseous mixtures containing hydrocarbons must be treated. This can serve recycling, emission protection or other operational requirements.
