Abstract
Abstract A reactor cooling system for cooling a reactor having an inlet and a discharge for the heat carrier comprises a pump housing which is arranged alongside of a cooler housing and is connected in parallel to the reactor and the cooler housing. An expansion tank for the heat carrier is mounted above and communicates with the pump housing and it also extends over the top of the cooler and surrounds a separator for the coolant which is mounted above the cooler housing. The cooler housing has a lower coolant chamber and contains coolant pipes which are connected between the coolant chamber and the separator and coolant is added through a coolant supply line connected through the separator and down to the coolant chamber. The coolant is added to maintain a predetermined level in the separator and the separator includes a vapor outlet for the discharge of accumulated vapor. A throttle valve is disposed between the connection of the cooler to the pump housing in order to vary the quantity of heat carrier which is circulated through the cooler.
