Matrix Engineering provided the structural and mechanical engineering necessary to replace a mist eliminator within the catalyst scrubber system at the Nashville, Tennessee plant. The new kynar lined FRP mist eliminator was designed with expansion of the scrubber system in mind. However, spatial constraints dictated we have a very close coordination with the vessel designer and fabricator for an almost impossible fit. The existing structural steel was also upgraded to accommodate the new heavier vessel. Besides structural design and detail drawings, we also provided vessel arrangement, fiberglass ductwork layout and details, and piping drawings.
