Output, purity and pressure

Note:

• All pressures which are not specially defined are the gauge pressures
• Nm³/h is defined as the volume at standard atmospheric pressure.
• The liquid output is calculated on the base of data of gas, and the pressure is calculated with 0 meter high at outlet of cold box.

Description:

        In liquid oxygen working condition, the supplement nitrogen from nitrogen pipeline mixing with the refluxed gas from liquefier after throttled, and after compressed through circulation nitrogen compressor, it is divided into two streams: one enters main heat exchanger to be cooled, and then it is fed into the high temperature expander where it is expanded, following which it goes out of cold box after being re-warmed in main heat exchanger, and goes back to the inlet place of circulation nitrogen compressor; the other one goes into the main heat exchanger following being boosted in the boosting ends of high temperature expander and low temperature expander to be boosted, part of which is led into the low temperature expander where it is expanded, and then it goes out of cold box after re-warmed in the main heat exchanger, and back to the inlet place of circulating nitrogen compressor; rest part is directly liquefied to liquid nitrogen.

       The liquid nitrogen is divided into two streams after being sub-cooled in liquid nitrogen sub-cooler, one stream goes into the oxygen heat exchanger first, and then goes out of cold box after re-warmed, and back to the inlet of circulation nitrogen compressor; the other stream backflows to the LIN sub-cooler after being throttled, and goes out of cold box after re-warmed.

The gaseous oxygen is liquefied by liquid nitrogen in the oxygen heat exchanger, and then it is sent out of cold box.

        In liquid nitrogen operating mode, he supplement nitrogen from nitrogen pipeline mixing with the refluxed gas from liquefier after throttled, and after compressed through circulation nitrogen compressor, it is divided into two streams: One flows into high temperature expander to be expanded following being cooled in the main heat exchanger, and then goes out of cold box after being re-warmed in main heat exchanger, and back to the inlet position of circulation nitrogen compressor; the other one enters into the main heat exchanger following being boosted in the boosting ends of high temperature expander and low temperature expander to be boosted, part of which is led into the low temperature expander where it is expanded, and then it goes out of cold box after re-warmed in the main heat exchanger, and back to the inlet place of circulating nitrogen compressor; another part is liquefied to liquid nitrogen directly.

The liquid nitrogen is sub-cooled in the LIN sub-cooler, and then sent out of cold box as product liquid nitrogen after being throttled.
