Process Engineering

Orion’s process engineering department meets all of our clients’ needs from feasibility studies through start-up and commissioning. Our engineers provide clients with a well-documented design for their project and the data needed for Process Safety Management (PSM) compliance. Proprietary calculation worksheets allow us to perform routine calculations efficiently and accurately, leaving ample time to work out difficult design questions that may arise. Additionally, Orion’s collection of process specifications and standards for fabricated equipment allows our engineers to quickly specify equipment.

Orion’s process engineers pride themselves in their scope development skills and delivering practical and safe designs. In addition to their extensive experience, our engineers use the latest technology systems to execute our clients’ designs, including:

  • AFT Fathom and Arrow – used for non-compressible and compressible flow applications, including: calculation of pressure drop; and flow distribution in liquid and low velocity gas piping and ducting systems.
  • Chem-Pak – used for comprehensive thermo-physical properties simulation on a wide range of fluids for AFT’s family of pipe flow modeling software products.
  • PHA Works 5 from Primatech – used for conducting Process Hazard Analysis (PHA) studies, such as HAZOP and What-If studies.
