| Abstract: | Using an expander cycle and using liquid nitrogen cycle separately for a nitrogen plant using air separation process and their energy balance are described.A comparison between two examples using separate cycles mentioned above is illustrated.The paper points out that it is feasible to use liquid nitrogen from external source as cold source instead of an expander.As a result,low power consumption,easier operation,less maintenance,higher nitrogen recovery ratio can be available. |
