Evaluation of the existing tank farm condensate recovery system hydraulics to determine throughput capacity, existing limitations, and options for increased capacity.
REFINERY TANK FARM CONDENSATE RECOVERY SYSTEM HYDRAULIC STUDY
The client operates an independent petroleum refinery in Montana. The client hired Process Engineering Associates, LLC (PROCESS) to conduct an evaluation of the existing tank farm condensate recovery system hydraulics to determine throughput capacity and current limitations. PROCESS developed a hydraulic model of the system using its licensed commercial process simulation software and tuned the model to plant data collected by PROCESS. Debottleneck options were then provided to improve the carrying capacity along with improving the existing pump station. The client implemented the low cost alternative of replacing the condensate recovery pump to match the pump curve to the existing system curve.
This project was on a tight execution schedule in order to recover valuable condensate into the boiler feedwater system. PROCESS was able to meet all schedule milestones. The deliverables resulting from this project, including preliminary process flow diagrams (PFDs) for the recommended modifications, a comparison of the pump curve to the hydraulic system curve, and an economic comparison of the available options to assist the client in choosing the best option for implementation, were compiled in a project report submitted to the client.
