Process Design Engineer with 13 years in oil and gas refining, including 8 years at bp Cherry Point. I lead capital projects from opportunity framing through FEL-2 and EPC detailed design across the process block and utilities—specifying heaters, exchangers, vessels, rotating equipment, hydraulic networks, relief, and flare. I combine process modeling, economics, permitting, and contractor oversight to take unit constraints from idea through startup.

Process Design Engineer
Business Development Engineer

bp | Cherry Point Refinery

2018 – Present

Lead projects from framing through FEL-2, then direct EPC detailed design to site standards through startup and post-startup safety review.

Work spans crude, coker, hydrocracker, DHDS, isomerization, sulfur recovery, tail gas, and flare.

  • Fired heater replacements
    • Lead replacement strategy for two fired heaters (40 and 190 MMBtu/hr) driven by tube integrity in the radiant and convection sections, including NSPS Ja reconstruction/BACT NOx limits and Washington Ecology air permitting.
  • Vacuum waste-heat recovery
    • Led a project to capture about 40 MMBtu/hr of waste heat from vacuum resid into vacuum distillate bottoms ahead of the vacuum-tower heater, unloading fired duty, reducing emissions, and eliminating mid-cycle heater outages so the heater stays on the planned outage cycle.
  • Renewable co-processing
    • Led hydroprocessing modifications (reactor, exchangers, high-pressure separators, condensers) that enable co-processing of renewable feedstocks up to 25% of unit capacity; now in operation, providing lower carbon-intensity fuels to West Coast markets.
  • DHDS slug-flow mitigation
    • Designed mitigations for slug-flow-induced vibration in the feed/effluent exchanger and heater piping after renewable co-processing created two-phase flow; a fresh-feed and recycle-gas bypass control system restored unit capacity without rate cuts.
  • Recovered-oil route
    • Designed a recovered-oil route to downstream diesel hydrotreating that eliminated recycle to fresh feed, freeing up to 1,400 bpd of crude capacity.
  • Business Development
    • Develop at least six capital ideas or process studies per year and present them to gatekeepers with a proceed or kill recommendation based on the business case; about half typically proceed.
  • Spent-caustic recovery
    • Led a refinery-wide spent-caustic recovery study to characterize how unit discharges combine in the utilities collection tank and the upset risk from hydrocarbons, HCl, and H2S; the work sets the basis for a capital project to treat the combined stream so it is safe to handle and discharge to the oily-water sewer.
  • Site SWMM (oily-water sewer)
    • Built and calibrated an EPA SWMM model of stormwater in the oily-water sewer network using operating data and field observations. The study set the basis for later infrastructure and capital projects, including safer handling of oily-water and stormwater loads.
  • Custody-transfer meters
    • Designed replacement of worn mechanical turbine meters on the Cherry Point truck rack with Coriolis mass flow meters, cutting product giveaway by up to 40% on customer loadings that need tight custody-transfer tolerance.
  • Hydrocracker recycle as intermediate feed
    • Developed a dynamic hydraulic model of a new route for hydrocracker recycle as intermediate feed and showed the existing system had enough head to cover the added losses; the reroute was implemented without significant hydraulic upgrades.
  • Coker-feed import
    • Designed an import and storage system so intermediate oils can feed the coker and bypass the crude unit, giving the site a new coker-feed source and more flexibility in coker operations.
  • Engineering Basics for Process Engineers
    • Co-teach bp’s Engineering Basics for Process Engineers course every two years to new process engineers from all sites (typically 15–25 students), covering the fundamentals they need to operate and troubleshoot assigned units.

Process Engineer

Anvil Corporation | Bellingham, WA

2013 – 2018

Process design for bp, Chevron, Phillips 66, and independents, concept through detailed design. Seconded to bp Cherry Point for relief FEL, hydraulics, and selected capital scopes.

  • Relief-system FEL
    • Seconded to bp Cherry Point for FEL on 20+ relief systems, closing 75 risk findings across five process units: HYSYS/Excel hydraulics, API 521 overpressure scenarios, and updated PSV sizing.
  • Lean-amine header relief
    • Redesigned Cherry Point’s lean-amine header relief system, checking hydraulics from each scrubber so the limiting vessel stayed within allowable accumulation and header backpressure did not derate PSV capacity.
  • Crude rail offload
    • Built a HYSYS Dynamics model of a 100+ railcar crude gravity-offload system to prove feasibility before construction.
  • ULSD lubricity injection
    • Developed a lubricity-additive injection system for ULSD that enabled Cherry Point to meet the new marine-fuel spec and sell ULSD to West Coast vessels.

Process Engineer (work-study)

Rio Tinto | Kennecott Utah Copper | Magna, UT

2010 – 2013

Supported copper-smelter operations through mass balances, equipment studies, and turnaround support.

  • Smelter mass balance
    • Analyzed the smelter mass balance to keep plant operation predictable.
  • Loesche mill study
    • Prepared a study of the Loesche grinding mill to troubleshoot furnace-feed issues.
