• Led process chemistry troubleshooting and analytical support for all Chemicals units at the Deer Park complex (light olefins, heavy olefins, aromatics and phenol/acetone)• Developed and deployed new analytical methods to support unit operations• Led the laboratory’s effort to convert the GC carrier gas from helium to hydrogen to reduce carrier gas costs and analysis times while improving low-level detection limits.

Us

• Led department’s membrane technology development program to drive understanding and strategic application of membranes in steam cracker recovery areas.• Developed a Windows software application to simulate separations in membrane modules (C++, Fortran, C#)• Consolidated recovery process technology knowledge and expertise to support major growth venture activities.

Us

• Led the idea generation effort to identify novel technology areas for use in the recovery section of olefins plants.• Evaluated co-product technology licensor offerings for use in major growth ventures• Established methodologies and led laboratory operations in effort to understand primary fractionator fouling.• Co-invented an advanced 2D-GCxMS data analysis method capable of deconvoluting overlapping peaks and quantify hundreds of reactive molecules in steam cracked gas oils.

Us

• Led the department’s foulant analysis activities, contributing to problem solving efforts that avoided millions of dollars of lost production.• Directed the work of multiple lab technicians and trained them when introducing new methods.• Developed and deployed a tar quality model to predict commercially relevant properties of steam cracked tar.• Led the on-site process chemistry support for the startup of an advanced liquids cracker in Singapore. • Discovered a previously unknown process safety risk associated with NOx gum formation and accumulation and communicated the findings to other companies in the industry.• Built up the department’s laboratory capabilities to become a global center of excellence for foulant analysis

• Designed and managed the execution of small capital projects in Texas and the Southern US from inception to close-out, including those involving high purity or toxic gases.• Commissioned a distillation column used to produce Ultima grade (6N4) ammonia, and executed projects related to expansion of that product line.• Supervised the maintenance staff at the La Porte and Pasadena plants. Was responsible for ensuring all routine and non-routine maintenance activities were completed on time.
