Dr. Kosta J. Leontaritis, affectionately known in the Gulf of Mexico circles as Dr. Wax, is founder and CEO of AsphWax, Inc. AsphWax's objective is to provide the Oil and Gas industry with laboratory testing, simulation, and consulting services in equipment development, modeling, problem solving, and chemical applications in the area of asphaltenes, waxes, hydrates and flow assurance.


Dr. Leontaritis supervises the day-to-day operations of AsphWax's state-of-the-art asphaltene and wax testing laboratory, teaches advanced courses in asphaltenes, waxes, hydrates and flow assurance, and is directly involved in the marketing and licensing of AsphWax's highly advanced asphaltene and wax flow assurance multiphase simulators.


Dr. Leontaritis did his undergraduate work in Chemical Engineering at the University of Illinois, Chicago. He obtained his MS in Chemical Engineering with focus in petroleum refining from the Illinois Institute of Technology, Chicago, and his Ph.D. from the University of Illinois, Chicago, in Chemical Engineering. His Ph.D. thesis concerned the development of his well known Thermodynamic-Colloidal Model (T-C Model) of Asphaltene Flocculation.


Dr. Leontaritis' "hands-on" experience on the design, operation, and maintenance of petroleum production, processing, transportation, and refining facilities covers the entire upstream and downstream oil industry including small independents, majors, service companies, and research organizations. Dr. Leontaritis' direct "hands-on" experience with "real" field asphaltene, wax, and hydrate problems coupled with his extensive experience in modeling and simulation using Equations of State and other asphaltene and wax models, which in most cases he developed



Dr. Leontaritis is a member of the American Institute of Chemical Engineers and of the Society of Petroleum Engineers. He has made many lectures as invited speaker in prestigious organizations. He has been serving as technical editor and symposium co-chair for professional societies and other research organizations relevant to the Petroleum Industry worldwide. He has also taught numerous courses in phase behavior, flow assurance, and asphaltene and wax deposition simulation and management.
