  • Reid vapor pressure determination
    Patent number: 4667508
    Abstract: The Reid Vapor Pressure of a hydrocarbon mixture consisting essentially of hydrocarbons selected from the same series is determined based on the actual temperature and vapor pressure of the hydrocarbons mixture. The thus determined Reid Vapor Pressure may be compared to a set point for the Reid Vapor Pressure with the results of the comparison being utilized to maintain the actual Reid Vapor Pressure substantially equal to the desired Reid Vapor Pressure.
    Type: Grant
    Filed: December 11, 1985
    Date of Patent: May 26, 1987
    Assignee: Phillips Petroleum Company
