- Fractionation Plant Water Treatment
Burns & McDonnell used design-build project delivery for an industrial water treatment plant for a natural gas fractionation plant. The treatment plant takes water from a nearby canal to an open-top, inclined plate clarifier. Coagulant, flocculent and bleach are added to the clarifier before the water is pumped continuously to the high-rate, open-top continuous backwash sand filtration units. The final stop in the treatment train is the 800,000 gallon factory-coated bolted steel tank that acts as a reservoir for process water, cooling tower water and fire water. The fire water goes through a fire pumphouse, which had to be specifically designed because it is in an NEC-classified area. Also included in the treatment design was a reverse osmosis skid to provide makeup process water.
Burns & McDonnell was responsible for process design, including Process & Instrumentation Diagrams (P&IDs), equipment design and selection, and vendor coordination, as well as the procurement of the fire water pump system.
