Case Study: Modelling Refinery ProcessesFlex Process
Flex Process modelled most of an oil refinery using Pro/II, giving the client a platform to test modifications off-line, try out new operating regimes, and run different feed stocks, with no risk to the process.
Case Study: Refinery Relief and Flare StudyFlex Process
Flex Process built dynamic models of all refinery units connected to two flare headers. By making sure the models matched plant performance, and running all identified scenarios, the client was provided with a comprehensive study, including recommendations to ensure a legacy flare header could remain in service, saving £millions in capital expenditure.

1. ExxonMobil Chemical, High Pressure
Polyethylene, Baton Rouge, LA
Full Time Employee: Machinery/Rotating Equipment Engineer Jun. 2014 – Present
Flawless Safety Performance:
Zero recordable loses due to active participation and promotion of company’s safety and loss
prevention programs (e.g. LPSAs, LPOs, PSSRs, NLIs, etc.)
Eliminated safety concern presented by area safety team by designing a custom fastener and
verifying design via SolidWorks FEA and by-hand beam stress analysis calculations
Eliminated lifting hazard by identifying and modifying a hydraulic cylinder lift to support, lower,
and raise large steel filter housings during filter change operations
Mitigated risk of autoclave decompositions (an environmental recordable event) by redesigning
foot bearing retainer ring with a 600% smaller stagnation zone
Cryogenic Centrifugal Sundyne Pump Reliability Resolutions:
Supervised teardowns/inspections/rebuilds to resolve abnormal split line leaks and seal reliability
Leverage knowledge from multiple sources for RCFA by soliciting internal and external resources
Constructed 3D models to perform FEA analyses and identify/correct LTA component designs
Prevented margin loss of 600k$/day and was presented with Technical and Engineering Award
Cooling Oil Pump and System Pressure Control Upgrades:
Generated hydraulic model to design a spillback loop to maintain optimal header pressure for
reducing cooling oil contamination and improving hypercompressor seal and packing reliability
Specified new pump/driver/base to mitigate single point of failure for multiple production lines
Captured a margin risk and reliability savings of 311k$/yr with a 12.4 B:C ratio
Hypercompressor Plunger Lubricator Double Block and Bleed Assembly Installation:
Collaborated with Autoclave Engineers to design first-of-kind DBB assembly for operations near
50kpsi to enable safe repairs of failed pumps without shutting down production lines
Engineered bracket in SolidWorks to support DBB assemblies and associated high pressure tubing
Margin improvements: A-D lines - 107k$/yr with 125% DCF; E&F lines - 163k$/yr with 196% DCF
Vertical Compressor Repair and Rod Load Reversal Corrections
Discovered significant damage to crosshead bore/pin/bushing consistent with calculations that
showed less than adequate rod load reversal during startup
Modified startup procedure to guarantee min rod load reversal during startup
Collaborated with OEM to engineer a replacement oversized pin/bushing that saved 1575k$ in
margin with a 131 B:C ratio (saved 63 days vs new part delivery)
Hypercompressor Health Summary Forms
Developed and stewarded monthly one-pagers of critical machine info for Major Machinery
