Note: 1. Nm3/h is defined as the volume at 0℃, 101.3kPa(A);

2. The liquid output is calculated from data of gas, and the pressure is calculated with 0 meter high at outlet of cold box.

 

 

Description:

 

   The plant employs a expansion turbine process in which the air is purified by molecular sieve, nitrogen is produced by means of double columns with expansion achieved through backflow.

   After the feed air is cleaned of dust and mechanical impurities in air filter, it is compressed to 0.95MPa in air compressor.

  The compressed air is then fed into air pre-cooling system to be cooled to 10 ℃, it becomes saturated.

  The saturated and compressed air flows into switched molecular sieve adsorbers where such hydrocarbons as H2O, CO2 and C2H2 are adsorbed from the air.

   A small part of purified process air is drawn out to be used as instrument air; the remainder is fed into main heat exchanger to be cooled to saturated state with the refluxed gas. The cooled air is fed into the bottom of nitrogen column for participation in rectification. The product medium pressure nitrogen is obtained at the top of nitrogen column while the saturated and oxygen-rich liquid air at the bottom of column and the liquid nitrogen at the top of column are throttled in the liquid air and liquid nitrogen subcooler and then into the corresponding postion of upper column.

   Follow the further rectification in the upper column, the low pressure nitrogen is obtained at the top, which will be sent to the user after being rewarmed in the main heat exchanger.

     The waste nitrogen which is withdrawn from the upper part of main heat exchanger goes into the subcooler and main heat exchanger to be rewarmed to a certain temperature, and then goes into the expander to be expanded. The expanded gas goes into main heat exchanger to be rewarmed, and then goes out of cold box, part of which will be the regeneration gas of molecular sieve, and the rest will be blow-off.

.  In order to prevent hydrocarbon from accumulating in condenser evaporator, a small stream of liquid drawn from oxygen-rich liquid air evaporation side is discharged as waste liquid.
