1, air cooling tower and water cooling tower using Bauer ring packing to bear the air, waste nitrogen and cooling water heat transfer carrier, which has a large flux, low resistance, high separation efficiency, operating flexibility and other characteristics. In the water-cooled tower, it makes full use of the cooling capacity of the recycled waste nitrogen to reduce the temperature of the chilled water before it enters the chiller, reducing the electrical load of the chiller.
2, large air separation unit purification system adsorption device is usually used in the vertical radial flow type, which can effectively reduce the air flow resistance and floor space. High efficiency molecular sieve adsorbents can save 5% of energy consumption in the regeneration stage compared to ordinary adsorbents. The small air separation units users with low pressure steam can also choose steam heaters instead of electric heaters. If the saturated steam pressure is not enough, the electric heater can be used in series to make full use of the steam energy and thus save electricity.
3, fractionation tower system on the tower and the tower using gauge packing, gauge packing with high separation efficiency, and can be a large load to change the characteristics of the working conditions, the general gas flow resistance in 5kpa or so.
4, liquid oxygen from the booster process is outside the compression of small air separation unit using more of a process form, than the conventional outside the compression process energy-saving significant.
DEAR air separation in long-term practice, through advanced technology and equipment to make air separation device energy saving and consumption reduction, for the user to reduce the operating costs of small air separation units, large air separation units and liquid air separation plants, improve economic efficiency.
