Abstract
Methods and apparatuses are provided for hydrotreating hydrocarbons. A method includes heating a start-up oil in a stripper liquid fraction heat exchanger during a start-up period, and heating a reactor with the start-up oil. The start-up oil is discharged from the reactor when the start-up period ends, and a standard operating period begins after the start-up period. A reactor effluent is produced by introducing a hydrocarbon stream into the reactor during the standard operating period, where hydrogen sulfide is produced from an organic sulfur compound in the hydrocarbon stream. Steam is produced in the stripper liquid fraction heat exchanger during the standard operating period.
