Comment Separation Processes

A new spin on liquid-gas separation

By Gerald Ondrey |

Last month, Innsep AS (Trondheim; Norway; www.innsep.com) and EagleBurgmann Norway (Skedsmokorset;www.eagleburgmann.no) began a collaboration to develop Innsep’s Lynx Separator technology for protection of EagleBurgmann’s Dry Gas Seal systems for compressors. Lynx is a new technology for removing entrained liquids much more efficiently and with a smaller footprint than conventional separators, such as those with stationary mesh contactors or cyclones. The heart of the Lynx technology is a sponge-like cylinder made of porous stainless steel, which is mounted inside a separator column, and held in place by airtight bearings (diagram). The cylinder is rotated by a magnetically coupled motor. As the wet gas enters the filter, liquids coalesce onto the large surface area and then are thrown by centrifugal force to the walls of the separator to be collected at the bottom. The added pressure drop across the Lynx due to the rotation of the mesh is insignificant, says Innsep’s R&D director Maria Fernandino. The patented technology was first invented by Fernandino and Innsep’s chief technology officer Carlos Dorao, who are both researchers at the Norwegian University of Science and Technology (NTNU; Trondheim; www.ntnu.no), from…
