Oil & Gas Refining Equipment

oil refineryANSYS FEA and CFD simulation software has been used extensively in the design and engineering of the Oil & Gas refinery equipment. A number of SimuTech customers are using ANSYS FEA and CFD software for Oil & Gas refinery projects.

SimuTech has completed many consulting projects directly associated with the refinery equipment for Oil & Gas.

In addition to simulation software and services, SimuTech is a leader in vibration diagnostics to the Oil & Gas industry.

FCC Blower Optimization

Design ElementChallengesSimulation Benefits
Optimizing Cracker Performance
  • Heat transfer to process tubes
  • Control of tube temperatures
  • Pollutant (NOx) reduction
  • Staged low-NOx burners would have flame roll-over
  • Wall and floor burner placements
  • Control process stream in tubes
  • Sample Case - ABB Lummus Global used simulation to:
    • Model flow and reaction in process tubes to get accurate tube temperatures
    • Identify initial design flaws
    • Optimize changes in wall inlet angles and floor burner placement
    • New design is up and running, performing as advertised at end-user site
FCC Blower Optimization
  • FCC performance is limited by blower performance
  • Coke on FCC catalyst burned off in the regenerator
  • The blower designed to draw air and supply it to the regenerator internal air blower manifold.
  • Blower efficiency was below 90%
    • Significantly less than that of other similar units
  • Sample Client Case Results and Benefits
    • Line from the ambient air inlet to the blower intake port simulated in search of flow distribution problems
    • Air flow through the line was strongly skewed by an unexpected interaction between two bends and the valve wafer in its normal open position
    • Flow concentrated on one side of the line at blower entrance, reducing efficiency
    • The equilibrium open position of the valve wafer could be adjusted.
    • Sidestepping of more expensive modifications
    • Potential for incremental capacity benefits exceeding $6 million/yr
