AED provided piping and electrical detailed design services to support tank farm berm improvements for a refinery. The brownfield project required rerouting of existing benzene piping due to the modifications and involved the development of isometrics and piping layout drawings. AED’s electrical team designed a heat trace system for the newly installed piping to prevent the benzene from freezing. Because AED's team was specifically built to be scaled to execute projects of this scope and size, the team was able to execute the project quickly, without error and under budget.

AED assisted in an installation investigation of (3) self-priming pumps for a refinery’s wastewater recycle pit. The severe vibrations from the pumps were causing intermittent problems with the ultrasonic flow meters leading to a $30k/month temporary workaround, prompting an investigation. AED’s mechanical team reviewed the pump specifications, contacted the manufacturer, and analyzed the installation. The result of the investigation showed the pumps were cavitating due to poor equipment selection, leading to the entrainment of air in the pumps lacking maintained minimum level controls. AED’s solution comprised of a restriction orifice allowing for smoother operation and reduction of pressure build up in the pump. Minimum-level logic was added to the DCS programming to support the new equipment.
