Petroleum Refinery Due Diligence Review

Process was subcontracted to provide a due diligence review of an operating refinery in Southeast Asia.  The client is an international capital investment firm that was considering purchasing the refinery. As a part of this project, the following tasks were accomplished:

• On-site technical review of refinery operations

• Spot checking of refinery documentation

• Preliminary process simulation of Crude Tower capacity

• Identification of general concerns

• Report generation and project summary.

A Chief Process Engineer from Process reviewed the process design documents (done by others), including the Process Flow Diagrams (PFDs), Piping and Instrumentation Diagrams (P&IDs), and miscellaneous equipment design information.  A trip to the Southeast Asia operating facility was performed, multiple site personnel were interviewed, current operations were reviewed, and refinery units were inspected from a process engineering point of view.  All units in the refinery were checked, including the following:

• Crude Distillation Unit

• Delayed Coker

• Bitumen Plant

• Solvent Distillation System

• Electricity Generation Turbines

• LPG Storage

• Nitrogen Unit

• Utilities

• Unloading Jetties

• Tankage

Process developed a report summarizing general perceptions of the refinery and potential future modifications that could result in higher throughput and/or profitability.
