waste gas scrubber design meets environmental permit requirements

When U.S. Steel needed to reduce emissions from the waste-gas discharge stacks of the pelletizing grate at its Keewatin Taconite facility, it called on Barr. We designed the layout for a system that included two new wet scrubbers, two new fans and motors, process ductwork, effluent handling, filter-press systems, and all required buildings.

Design engineering included new structural supports, building and equipment foundations, water piping, pumps, a water treatment system with a new thickener, truck loadout area, electrical power distribution, instrumentation, motor control centers, and electrical building systems. We also provided pump specifications and the installation design for the facility’s hydrated lime unloading, storage silo, feeder, mixing tank, and pump metering system.

To minimize disruptions in production, most of the construction took place while the plant was in operation. The $28 million emissions-control system has been in operation since 2006.
