Efficient process to produce tonnage nitrogen.

Author(s) : AGRAWAL R., WOODWARD D. W.


For large tonnage nitrogen generators energy consumption is the major portion of the overall cost. Three novel process cycles using dual reboiler condensers in the stripping section of the low pressure column of a double column process are suggested. By a judicious choice of the condensing fluids in each of the reboiler condensers the total power consumption for the nitrogen production can be substantially reduced.
