KAUST researchers create membranes to cut industrial gas energy use

Researchers at King Abdullah University of Science and Technology, in collaboration with scientists from China and France, have developed a new design for advanced membranes based on metal-organic frameworks (MOFs) to separate industrial gases more efficiently. The team managed to increase the material content within the membrane to over 90% while maintaining its flexibility and durability. They also succeeded in manufacturing 20-meter-long coils using continuous production techniques. Experiments demonstrated that these membranes can trap carbon dioxide and purify hydrogen and propylene for up to 150 days, while potentially reducing purification costs by up to 80% compared to traditional distillation. This achievement is significant because gas separation processes account for approximately 15% of the world's total energy consumption and could contribute to energy savings and enhanced industrial sustainability in the petrochemical, natural gas, and hydrogen sectors.
