REMOVED: Structural Optimization of Membrane Based Biogas Upgrading Processes

Selected Methods of Advanced Biogas Upgrading

The upgrading of biogas for the production of biomethane to be injected to the natural gas grid has gained significant importance in recent years. It is often considered to be superior to the production of electricity and district heat with internal combustion engines mainly because of better energy utilisation, higher flexibility and beneficial economic prospects. Biogas upgrading is commonly ...

Physical Backwash Optimization in Membrane Filtration Processes: Seawater Ultrafiltration Case

Seawater ultrafi ltration (UF) as a pretreatment of reverse osmosis (RO) process in a thermal power plant was investigated using a 100 kDa hollow fi ber membrane. The choice of the UF physical backwash conditions remains arbitrary or ensuing from a sensibility study. As the optimum must take into account the factors interactions, we led a response surface study to analy...

Membrane-based technologies for biogas separations.

Over the past two decades, membrane processes have gained a lot of attention for the separation of gases. They have been found to be very suitable for wide scale applications owing to their reasonable cost, good selectivity and easily engineered modules. This critical review primarily focuses on the various aspects of membrane processes related to the separation of biogas, more in specific CO(2...
