BORSIG Vapour Recovery Unit

The BORSIG Vapour Recovery Unit (VRU) combines absorption/condensation and membrane separation. The unit comprises a liquid ring compressor, scrubber column, membrane stage and vacuum pump. The BORSIG VRU process effectively treats gas streams containing hydrocarbons in order to meet the required emission limits. BORSIG VRUs are equipped with high quality machinery and materials only. The combination of reliable instruments and the latest state-of-the-art control systems enables the fully automated operation of the unit.

The mechanical design of the system is based on a skid-mounted, pre-assembled principle. This can be a standardised layout but also tailored to meet the particular site requirements of the customer.
