Petroleum Refinery Due Diligence Review

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.
