Alexander Chen-Aun Ballantyne
Experienced Operations Leader | 10 Years in Refining, Petrochemicals & Water Treatment
With 10 years of hands-on operations experience, I specialize in crude distillation, C3/C4 Merox treating units, Claus and SCOT sulfur recovery, steam methane reforming (SMR) hydrogen plants, gas oil hydrotreaters, and water chemical treatment systems. My background includes managing both process and utility systems to ensure consistent product quality, equipment reliability, and environmental compliance. I have successfully coordinated multiple unit turnarounds, including the development and execution of LOTO plans, clean-out procedures, and comprehensive shutdown/startup protocols. I've also contributed to optimizing water treatment processes, including boiler feedwater quality, cooling tower chemistry, and corrosion control strategies to support plant reliability and efficiency. For the past 4 years, I have served as a Shift Supervisor, overseeing daily plant operations, personnel management, scheduling, and ensuring strict adherence to standard operating and emergency procedures. I focus on implementing industry best practices to promote safety, operational excellence, and environmental stewardship. In addition to my supervisory responsibilities, I've taken on key roles covering for Process Supervisors, managing daily maintenance planning, process optimization, and ensuring all units including water treatment systems operate within environmental and reliability limits. I have also played a large role with the cleaning and idling of my Last facility in preparation for idling and closure. Currently I am employed as a Stationary Engineer with Los Angeles County where I operate boilers and industrial chillers. As I look to expand my career with your company, I bring a strong work ethic, commitment to safety, continuous learning, and a results-driven mindset.
