Extending Membranes’ Reach Across the CPI

By Mary Page Bailey |

Advances in next-generation materials and assembly techniques have enhanced membranes’ effectiveness in numerous applications Membranes are one of the primary technologies used for separations. While they may be best known for their use in water-treatment operations, advances in membrane technologies have expanded their use into many areas, including the mining, oil-and-gas, petroleum-refining and industrial-gas sectors. These advances have also allowed for membranes to better address the myriad challenges faced in water-treatment facilities. This article examines several new membrane technologies used across a range of chemical process industries (CPI) sectors.   Olefins separation Advances in membrane materials have enabled their use in complex separations applications, including those involving various industrial gases and olefins. For instance, with the development of a proprietary, silver-facilitated membrane, Compact Membrane Systems (CMS; Newport, Del.; www.compactmembrane.com) aims to provide an efficient technology for separating olefins from paraffins. The intent is that these membrane systems, called Optiperm, can be installed alongside distillation columns or reactors for debottlenecking, retrofits and capacity…
