Abstract
A coil-wound heat exchanger with mixed refrigerant shell side cooling that is adapted to reduce radial temperature maldistribution by providing tube sheets at one end of a warm bundle that are each connected to tube sheets in a single circumferential zone and are in fluid flow communication with a control valve. Tube sheets at the other end of the warm bundle are each connected to tube sheets in a single radial section and in multiple circumferential zones. A temperature sensor is provided in each circumferential zone. When a temperature difference is detected, one or more of the control valves is adjusted to reduce the temperature difference.
