Slag Conveying and Barge Loading


Cement Producer


Southeast United States




The goal of this project was to install a new system to pneumatically convey slag cement from existing storage silos to oceangoing barges. The design of the pneumatic pipeline needed to traverse over 1,000 feet from the existing silos to the water’s edge, including underground and aboveground sections. In addition, the pipeline was designed to accommodate a high throughput rate (330 mtph) and a high product temperature (approx. 200° F). Pipe stress analysis and computational fluid dynamics analysis were completed to optimize the piping layout and manifold design. Since loading operations were conducted on a dock owned by the Cape Canaveral Port Authority, the design team prepared custom pipe skids to allow for expeditious pipe set-up and removal. New equipment was required for the system, including: pneumatic pump, air compressors and a closed loop cooling system. A new compressor room was designed to accommodate the new equipment.
