ABSTRACT:
A method is disclosed for obtaining an early detection and warning of a dangerous temperature excursion in a process using one or more hydrocarbon hydroprocessing reactors operating under otherwise ordinary hydroprocessing conditions. The warning is obtained by monitoring the specific gravity and/or methane content of the light gas fraction of the reactor effluent product stream. Pursuant to the warning, one or more suitable quenching means are employed to control the excursion.
