Problem The chemical refinery environment was filled with high levels of hydrocarbons and other airborne particulates. Its proximity to the ocean resulted in heavy precipitation, periodic salt spray, and fog events. All of these variables contributed to excessive axial compressor fouling, which resulted in reduced output and offline compressor washing to recover performance. The operator approached AAF as a world leader in gas turbine HEPA inlet filtration solutions looking to eliminate compressor fouling and the need to offline wash the turbine. Case Study - HEPA Filter Upgrade Chemical Cogen Plant in Houston, Texas The site had two (2) 40.0 MW GE Frame 6B units that were being operated in a co-generation application. The units operate within a large chemical refinery and are with
