Industrial Chemical Process Design

DOUGLAS L. ERWIN, P.E. is a practicing process engineer for engineering design and construction companies, major refinery-operating companies, and major chemical product companies. His project assignments have ranged from daily, routine technical services in refineries through the conception of new, complex, first-of-their-type patented processes. His chief quest in engineering practice has been to extend our knowledge beyond commercial process-simulation software, covering the severe technology gaps these packages miss. Process unit operation equipment, design and rating of fractionation equipment, three-phase separation equipment, packaged plant cost analysis, and equipment emergency pressure relief have been his main fields of accomplishment. Since graduating from Lamar University with a BS in chemical engineering in 1956, he has achieved these accomplishments in such locations worldwide as Korea, Saudi Arabia, Indonesia, Peru, Singapore, Canada, Alaska, the United Kingdom, Europe, Africa, Egypt, and the United States. He is a registered Professional Engineer in Texas by written examination. He is accounted by clients worldwide to be an expert consultant on code safety practice, the design and operation of oil and gas production and gas processing plants, and refinery liquid-liquid extraction design and operation.
