Vacuum Distillation Process Steps — SchuF Fetterolf Valves

topping unit Process overview Crude distillation is the first major process in a refinery. All crude oil entering the refinery passes through the atmospheric topping unit on the way to be further processed in downstream units. Crude oil is first washed in desalting to remove salts and metals that could cause corrosive damage or catalyst deactivation in downstream units. After desalting the
