Abstract: The invention provides a process and an apparatus for the production of ethylene oxide from ethylene. Ethylene and oxygen are supplied to reactor tubes, wherein the reactor tubes are held by upper and lower tube sheets in a reactor vessel. The reactor vessel has a separation grid, dividing the reactor vessel into an upstream zone and a downstream zone. Coolant is supplied to the upstream zone from an upper coolant circuit and is removed from the upstream zone to the upper coolant circuit. A portion of coolant is removed as vapour from the upper coolant circuit. Coolant is supplied to the downstream zone from a lower coolant circuit and is removed from the downstream zone to the lower coolant circuit. Additional coolant is added to the lower coolant circuit. There is net flow of coolant through the separation grid from the downstream zone to the upstream zone.
