Title: Impact assessment of reducing gasoline volatility

Principal Investigator / Author(s): Frederick, Franklin P.

Contractor: Bonner & Moore Management Science

Contract Number: a2-051-32


Research Program Area: Emissions Monitoring & Control

Topic Areas: Mobile Sources & Fuels, Stationary Sources


Abstract:

This report documents a study of the potential impacts on hydrocarbon emissions, on vehicle performance and on refining operations, investments and costs of restricting volatility of gasoline sold in California during the summer. Current volatility limits require a vapor pressure of no more than 9 psia. Assessments of impacts were made for restrictions of 8, 7 and 6 psia fuels in two future situations based on 1985 and 1990 crude and product forecasts. Results cover emissions effects in terms of vehicular exhaust and evaporative losses as well as non-vehicular evaporative losses. Vehicle performance effects are defined in terms of cold start, warm-up, driveability and safety considerations. Industry-level refining costs are developed in terms of raw material, capital and operating components. Typical refining situations are also examined.
