Dear [Hiring manager's name],
At Sabine Refining Partners I'm the process engineer of record for a 28,000 barrel-per-day hydrotreater, which means operations calls me first when a temperature or pressure reading drifts outside normal and nobody yet knows why. I'm applying for the Process Engineer role at [Company name] because your unit's recent throughput push is exactly the kind of live troubleshooting and monitoring work I already do daily.
When our reactor's pressure drop crept up over three months, I traced it to catalyst fouling using trended lab and process data instead of waiting for the next turnaround, and timed a partial catalyst change that recovered 4% of unit capacity without an unplanned outage. I also rebuilt our daily unit monitoring spreadsheet into a set of trended control charts that caught a compressor efficiency decline six weeks before it would have tripped on high vibration.
I pull and trend data from our plant historian daily, run heat and material balance checks against design basis in Aspen HYSYS, and write the technical justifications operations needs before they change an operating limit. I work the unit's daily morning meeting as the engineer who already knows what changed overnight, not the one finding out during the meeting.
I'd welcome the opportunity to bring that same live-monitoring discipline to [Company name]'s unit, and I can walk through the catalyst fouling diagnosis in an interview. Thank you for your time.
Best regards,
Chloe Garcia
