The commissioning for pilot scale hollow fiber membrane contactor on CO2 removal from natural gas was successfully conducted in a gas process plant located at Malaysia east coast, which is jointly developed by Prof. Cao Group (DNL0905) of Dalian Institute of Chemical Physics CAS (DICP) and Malaysia Petroliam Nasional Berhad (Petronas).
The system operated continuously and stably for 72 hours, the results indicated that all process parameters met the contract requirements. It is the world`s first system to purify the high pressure natural gas by hollow fiber membrane contactor. The unit adopted firstly the PTFE hollow fiber high-pressure membrane absorber jointly developed by DICP and Shanghai Bi Ke Clean Energy Technology Co., Ltd (“CECC”), the performance indicators of which also satisfied the contract requirements for the membrane development.
The MBC system integrates the advantages of membrane separation technology and traditional adsorption process and is proved to be low energy consumption, high separation efficiency, high recovery rate of natural gas, compact device with small footprint, operation friendly, and other superior properties. The innovative technology can be used not only for acidic gas removal from natural gas (especially on offshore platform), but also for other areas like biogas purification and CO2 capture of flue gases.
