An auto parts manufacturer was having opacity issues from their existing scrubber exhausting two large forges. They contacted Monroe for a Wet Electrostatic Precipitator to remove smoke and particulate, but after further engineering evaluations internally, they decided that one larger, taller stack would bring them into compliance. Monroe was selected to design and supply the new stack, ductwork, booster fan, and turnkey installation.
Monroe Environmental engineers designed the 120 ft. stack according to ASME STS-1 with a design wind speed of 120 MPH. The stack was designed to accommodate an additional 20 ft. height in the future. New ductwork, fan, and supports were also designed and supplied.
Monroe’s construction team completed the installation, making schedule adjustments to allow the plant to maintain maximum production uptime. The customer was happy enough with Monroe’s work even before the installation was complete to place an order for a new Mist Collector to control fumes inside the plant. A great job all the way around!
