Abstract

A process for liquefying a tube side stream in a main heat exchanger is described. The process comprises the steps of: a) providing a first mass flow to the warm end of a first subset of individual tubes, b) providing a second mass flow to the warm end of a second subset of individual tubes, c) evaporating a refrigerant stream on the shell side; d) measuring an exit temperature of the first mass flow; e) measuring an exit temperature of the second mass flow; and, f) comparing the exit temperature of the first mass flow measured in step d) to the exit temperature of the second mass flow measured in step e), the process characterized in that at least one of the first and second mass flows is adjusted to equalize the exit temperature of the first mass flow with the exit temperature of the second mass flow.
