1.3 Process description:
Air enters the suction air filter and after being removed of dust and other mechanical contaminants in it, it is compressed to the pressure of 1.0MPa by air compressor. The Air getting out from the air compressor is cooled to 8℃ by the air-precooling system and separated condensing water in the subsequent water separator. Then it is taken into the molecular sieve adsorber for removing H2O, C2H2 and CO2. There are two molecular sieve adsorbers which operate on a staggered cycle, i.e. one vessel is adsorbing the contained impurities while the other is being reactivated by waste nitrogen from the rectifying column.
Then the cleaned air is divided into two streams, one is taken into the rectifying column and cooled by the return waste nitrogen, oxygen,expander air through the main heat exchanger. The steam-liquid air mixture is taken into the lower column for rectifying, and herein the pure nitrogen from the top of the column enters into the evaporator-condenser and condensed by liquid oxygen from the upper column. A part of the liquid nitrogen is fed to the lower column as reflux. The other part after sub-cooling apart two parts after throttled. One part enters into the top of the upper column, the other part enters LN storage tank as product.
Another clean stream enters the main heat exchanger, And gets out from the middle and cold end of the main heat exchanger enter into the turbine expansion to generate most refrigeration for need of the plant's operation. After the expanded air return to heat exchange.
The LOX of 99.6%O2 is drawn from oxygen side of the evaporator-condenser, some of them enters storage tank as product. If need gas oxygen for filling cylinder, boosts the pressure of liquid oxygen by liquid pump to 150bar, then gasify it by vaporizer, and fill to the cylinders.
The waste nitrogen from the top of the upper column is warmed up by the sub-cooler, then get into the backflow expander to generate more refrigeration; after that, the waste nitrogen go back to the main heat exchanger to recover the refrigeration. When it gets out of the cold box, a part of waste nitrogen goes to the regeneration molecular sieve absorber and other part is blow down.
1.4 Characteristics of the plant:
1.4.1 Purifying air by molecular sieve adsorption makes the process simple, start-up and operation easy and safe, switch-over loss small and rectifying condition stable.
1.4.2 By using the pre-cooling system to cool the air with normal temp. Thus it makes the molecular sieve adsorbent in good condition.
1.4.3 For the use of the automatically controlled filter, the air bearings turbo-expander and the aluminum plate-fin heat exchanger, the stability, safety and reliability of the whole plant are improved greatly.
1.4.4 By using a new construction of the evaporator-condenser to avoid the accumulation of C-H chemical compounds.
