Objective:

Improve chemical, energy, manufacturing and metallurgical operations performance, profitability and value by applying my advanced chemical engineering and cost expertise to analyze technology developments, acquisitions or existing operations particularly those related to new products, environmental remediation and process optimization.

Experience - Company, Positions & Duties:

Matches, Principal Engineer, provide engineering support to take process from laboratory to pilot plant; from pilot plant to first commercial process; and to de-bottleneck existing processes. This includes guiding development of plans, and preparing process design, costs, life cycle, competitive position and customer value studies.

Kerr-McGee Corporation (Engineering Dept.), Principal Engineer, Provide capital and operating cost estimates for research and environmental projects, guide and develop operating cost estimates and procedures. Guide remediation technology choices for over $100 million in environmental work. Sponsor development of operating cost estimates and development procedures for preparing these estimates. Provided processing engineering for plant construction and remediation efforts. Provided process engineering support during construction of sodium chlorate and waste water purification units.

Kerr-McGee Corporation (Planning & Evaluation/Process Engineering Departments), Principal Engineer, Planned, evaluated and guided $25 million per year research efforts and proposed alternative opportunities. Reviewed and recommended acquisitions of technologies and companies. Performed techno-economic assessments of opportunities. Selected technology for up-grading 300 million tons of low rank coal.

Anaconda (ARCO), Technical Manager Hydrometallurgical Research/Senior Scientist/Senior R&D Engineer, Supervise laboratory and pilot plant studies of hydrometallurgical research on metals extraction. Consult on gold, silver, uranium and copper hydrometallurgy, and on bulk metal extraction methods. Help design, construct and operate a gold plant in New Brunswick, Canada and a silver plant in Darwin, CA. Develop a roasting technique for refractory uranium ore. Help develop a copper powder production process.

Chevron, Engineer/Technical Service Engineer, Design, purchase and construct heat exchanger and compressor systems for refineries and petrochemical units. Provide technical service to ammonia, nitric acid, ammonium nitrate, pesticide, complex fertilizer and garden-and-home production operations.
