  • METHOD OF COOLING A HYDROCARBON STREAM AND AN APPARATUS THEREFOR
    Publication number: 20110168377
    Abstract: In a method of and apparatus for, cooling a hydrocarbon stream, a hydrocarbon stream (45) to be cooled is heat exchanged in a first heat exchanger (50) against at least one refrigerant stream (145b, 185b) having a first refrigerant stream flow rate (FR1), to provide a cooled hydrocarbon stream (55) having a cooled hydrocarbon stream flow rate (FR2) and at least one return refrigerant stream (105). The first refrigerant stream flow rate (FR1) and the cooled hydrocarbon stream flow rate (FR2) are adjusted as follows, until an inputted first set point (SP1) for the first refrigerant stream flow rate (FR1) is achieved.
