| Abstract: | The process and parameters of the main heat exchanger of an air separation plant employing internal compression process are briefly described.Calculations are made using software Mathcad 7 0 and curves for heat transfer temperature difference profile within the main heat exchanger are plotted.Furthermore the temperature difference profile within the main heat exchanger is analyzed.At last the relationship between heat transfer temperature difference and non-reversing losses is discussed in a brief way. |
