Hot Hydrogen Stripping Method for Hydroprocessing catalysts
Hot Hydrogen Stripping is the dry-out process of spent hydroprocessing catalysts at high temperatures with the help of hydrogen gas. The process is normally applied during turnaround for the replacement...

Avoiding Temperature Runaway in Hydroprocessing Reactors
Temperature excursion or temperature runaway is the abnormal process condition at which catalyst bed temperatures go high beyond the normal operating limit on account of uncontrolled hydrocracking reactions. During a...
