Patent number: 7341112Abstract: A firefighting training fluid (FFTF) comprising a paraffin blend. The blends of paraffins typically have no less than about two carbon atoms and no more than about twelve carbon atoms. The blends of paraffins may possess Reid vapor pressures in the range from about 2 to about 6.5 pounds per square inch. The blends also typically possess an initial boiling point of not less than about 80 degrees Fahrenheit and an end boiling point of not more than about 370 degrees Fahrenheit. The blends burn relatively cleanly and keep emissions of volatile organic compounds, compounds containing sulfur, smoke, particulates, olefins, and aromatics to a minimum. The blend components mixed to create the blends of paraffins are controlled in order to maintain Reid vapor pressure and initial and end boiling points. Oxygenates may be added to an FFTF in order to further reduce smoke emissions.Type: GrantFiled: March 28, 2006Date of Patent: March 11, 2008Assignee: Chevron Phillips Chemical Company LPInventors: Dennis G. Doerr, Nancy W. Eilerts, Don E. Burnett, Daniel M. Coombs, Eric J. Netemeyer, Kirsten N. Caswell

Patent number: 4885080Abstract: A heavy crude oil is fractionated into at least three liquid fractions which include a distillate fraction boiling in the 400.degree. F.-650.degree. F. range and a 650.degree. F.+ boiling range residuum. The distillate cut is hydrodesulfurized and the residuum is hydrodemetallized.
