Hollow fibre membrane modules consist of hundreds of spaghetti-like tubes which maximise contact between the gas and the membrane surfaces. Flue gas passes across the outside of the tubes but only CO2 passes through to the inside, thereby being separated and captured.
A comparable process is used to purify water. A related application of this principle was recently reported by scientists at the Virginia Commonwealth Univeristy in the USA (read more here).
“The new membranes are highly selective for carbon dioxide in the lab but until we trial them with real flue gas we won’t see how well they stand up to industrial conditions”, says Professor Dianne Wiley, CO2CRC Capture Program Manager.
The equipment, comprising a custom built rig, has been installed at Delta Electricity’s Carbon Capture Research Facility at Vales Point Power Station. The Vales Point rig is able to test three hollow fibre modules at a time, providing the flexibility to test a range of new membrane formulations.
It is hoped that a successful trial will lead to a technology bringing down the price of capture. Hollow fibre membranes have the potential to substantially reduce the energy required to capture CO2, while having a smaller environmental and physical footprint than other systems such as the use of amines.
The project is funded by Australian National Low Emissions Coal Research & Development (ANLEC R&D) and supported by Delta Electricity.
A survey of events in the field of nuclear and radiation safety relating to Russia and Ukraine.
Russian president Vladimir Putin has told the United Nations atomic energy watchdog that Russia plans to restart Ukraine’s embattled Zaporizhzhia nuclear plant, currently occupied by Russian troops and technicians, fueling worries about a serious nuclear accident on the front lines of a grinding military conflict.
Wednesday, April 10, 2024 | Brussels, Belgium – Today, the European Parliament approved the newly revised Construction Products regulation (CPR)...
Recent attacks on Ukraine’s Zaporizhzhia nuclear power plant "mark the beginning of a new and gravely dangerous front of the war," the UN atomic agency's director general said last week.
