| Abstract: | Decreasing the temperature difference at hot end of main heat exchanger is the key factor to decrease the cold loss and in turn the energy consumption of air separation plant. The methods to control the temperature difference at hot end of main heat exchanger of 30000 m^3/h and 60000 m^3/h air separation plant of Oxygen Co. , Ltd. , Wuhan Iron and Steel Group are described, the advantages and weaknesses of the both control methods are analyzed, and the meaning of lowering the temperature difference at hot end for decreasing the cold loss due to incomplete heat exchange is explained. |
