US Patent 8425663 for Polarex®, an extractive separations technology, was approved on April 23rd, 2013. On April 23rd, 2013 US Patent 8425663 for Polarex®, an extractive separations technology was approved. Pentair’s Director of Sales and Process Technology, Carl Hahn, Ph.D had a leading role in the development of the breakthrough technology. Polarex® provides gas processors, chemical manufacturers, and refiners dramatically improved separation of entrained and dissolved contaminants. It is designed to replace conventional water wash and solvent scrubbing towers. “Polarex is a robust platform which can be applied across a number of challenging applications to displace conventional extraction methods.” Dr. Hahn explained. Conventional approaches to washing or scrubbing are often limited by contact efficiency and subsequent separation efficiency, resulting in limited performance and large capital investments. The Polarex® platform was developed utilizing advanced micro and nano-fiber technology to create a single stage, high efficiency, structured contactor/separator.
