Desulfurization of gasoline.

J E Berger

    Environmental Health Perspectives
    |April 1, 1975
    PubMed
    Summary

    Producing low-sulfur gasoline requires new hydrotreating technology, as component reallocation compromises fuel quality. This study assesses the refinery impacts of implementing this essential sulfur removal process.

    Area of Science:

    • Petroleum refining
    • Chemical engineering
    • Environmental science

    Background:

    • Gasoline blending streams have variable sulfur concentrations.
    • Reallocating components cannot meet low-sulfur demand without impacting fuel quality.
    • Catalyst-equipped automobiles may require low-sulfur unleaded gasoline.

    Purpose of the Study:

    • To evaluate the necessity of hydrotreating technology for low-sulfur gasoline production.
    • To assess the impact of sulfur removal on a petroleum refiner's operations.
    • To analyze the effects of implementing hydrotreating facilities.

    Main Methods:

    • Examining the limitations of component reallocation for sulfur reduction.
    • Outlining the requirements for installing hydrotreating process equipment.
    • Analyzing the consequences of sulfur removal at two distinct levels.
    • Discussing impacts on time, capital, and energy expenditures.

    Main Results:

    • Component reallocation is insufficient for producing significant quantities of low-sulfur gasoline.
    • Hydrotreating technology is essential for meeting future low-sulfur gasoline demands.
    • Implementing hydrotreating facilities necessitates significant investments in time and capital.
    • Increased energy consumption is an associated cost of hydrotreating.

    Conclusions:

    • Meeting the demand for low-sulfur gasoline requires adopting hydrotreating technology.
    • Petroleum refiners must prepare for the operational and economic impacts of this technology.
    • Strategic planning is crucial for integrating hydrotreating processes and managing associated costs.
