UREA INFRASTRUCTURE PROJECT

POWER UTILITY NORTH CAROLINA

As part of a design build effort, PENTA provided complete engineering and design for a series of Urea Infrastructure projects. The scope of this project consisted of adding a utility-grade Urea Liquor unloading, dilution, storage and transfer system that can be used with the Selective Non-Catalytic Reduction (SNCR) systems at four (4) of the Power Companys sites. Urea Liquor is delivered to each site by rail car or tanker truck. These new facilities provide for the unloading, dilution and storage of urea liquor, and for the transfer of the liquor for injection into the SNCR system. The equipment requirement at each site varied, based upon the existing equipment and site conditions at each location. PENTA worked closely with our construction partner to identify these differences and deliver site-specific systems.

Major pieces of equipment included: Urea Delivery Skids including pumps,

piping, valves and instrumentation Dilution Water Skids including pumps,

piping, valves and instrumentation Truck Unloading Stations Large capacity, insulated, FRP Holding

Tanks with heating pads

PENTAs design and engineering role included: Process design/ P&ID development General arrangement drawings Piping plan and details drawings Piping isometric drawings Pipe supports Civil site plan drawings Structural foundation plan and detail
