BORSIG Hydrocarbon Recovery Unit

The BORSIG Hydrocarbon Recovery Unit is a portfolio of specially developed and customised process solutions to meet emissions legislation and minimise the loss of product and profit by the recovery of valuable hydrocarbon.
The membrane separation is combined with other unit operations such as absorption, condensation, extraction etc. These hybrid processes are very efficient and enable the customer to operate at the highest economic and ecological efficiency.
A typical application is powder degassing in slurry-type PE plants. Polymer is flashed and stripped with hot nitrogen and the released purge gas consisting of nitrogen and solvents like butane, pentane and hexane can be processed using a sophisticated BORSIG hydrocarbon recovery technology. The liquefied solvent and the purified nitrogen can be re-used.
