DEAR Air has a number of patented inventions, of which the "ultra-low discharge pressure and energy saving patent" is the leading one in China. The innovative five systems are mainly achieved by reducing the discharge pressure of the air compression system; reducing the resistance of the air cooling tower of the encounter cooling system, the adsorber of the purification system and the flow meter of the control system; upgrading the fractionation tower system by replacing the upper tower, the lower tower and the argon tower with a new PLUS gauge packing to improve the distillation efficiency, adopting a new structure of the plate-type heat exchanger to reduce its operating resistance and using a multi-layer main cooling method to reduce the heat transfer temperature difference.
The industrial design of the large air separation plant was successfully completed through the joint efforts of technicians and commissioning staff. The successful application of these technologies will meet the current control requirements of a large proportion of users and will provide the technical basis for continued improvements in the condition of the equipment. Compared with similar products of similar enterprises in China, it is at the leading level and is highly competitive in terms of technology and quality of implementation. The design will be applied with the sale of the product and will have a broad market prospect and will improve the quality of small air separation units, large air separation units and liquid air separation plants
