New material industry solutions

DEAR air separation combined with international advanced technology ensures the equipment is safe and more reliable, and provides multiple sets of fine air separation equipment for users in the new material industry, which have won unanimous praise from users. Adopt molecular sieve adsorption, full-pressure low-pressure process technology of turboexpander refrigeration. This device includes: air filtration system, air compression system, air pre-cooling system, molecular sieve purification system, turbine expansion unit, oxygen pressure system, nitrogen pressure system, liquid Storage system, instrument control system, electric control system. After removing the mechanical impurities such as dust in the air filter, the raw air enters the air turbine compressor, compresses the air to the required pressure, and then enters the air cooling tower for heat exchange with water and then enters two alternate molecular sieve adsorption. Device, where impurities such as moisture, CO2, C2H2 in the raw air are adsorbed by the molecular sieve. Part of the gas is drawn from the middle of the main heat exchanger, enters the expander, and the expanded air enters the upper tower. After the air enters the main heat exchanger, it is cooled to the saturation temperature by the return gas and enters the lower tower with a small amount of liquid. After the air is initially rectified by the lower tower, an oxygen-enriched liquid air is obtained in the lower tower. After the liquid air is cooled by the cooler, it is throttled into the upper tower. After the upper tower is further rectified, oxygen at the bottom of the upper tower is obtained with a purity of 99.6% The oxygen of this product is reheated by the main heat exchanger and then sent out to the user after being discharged from the cold box. 99.999% nitrogen is obtained from the top of the upper tower, and it is returned to the cold box after being reheated by the cooler and the main heat exchanger. The polluted nitrogen is led out from the top of the upper tower, reheated by the cooler and the main heat exchanger, and then exits the cold box. After being heated by the regeneration heater, it is used as the molecular sieve regeneration gas and the excess gas is vented.

Large air separation unit KDON (Ar)-13000/26000-400 solution for new material industry
New material industry is a new field with vitality and development potential in chemical industry. New chemical materials refer to the advanced materials with excellent performance and function emerging or developing in the field of chemical industry. They are knowledge intensive and technology intensive materials with high technology content and high value. In the fine chemical industry, advantageous enterprises are actively building intelligent digital workshops, accelerating the application of intelligent logistics management technology and unit in the production process, and promoting digital control, real-time monitoring of status information and adaptive control. DEAR air separation can provide customers with intelligent air separation unit and overall operation services, help customers develop rapidly in the industry, and constantly improve the construction of intelligent detection and supervision system, so that customers can reach a new level of intelligent management of air s
1500/100 Y-type solution for small air separation plant in new material industry
The new material industry system of our country has been initially formed and the development situation is good. With the introduction of national strategic planning such as "The development plan of national strategic emerging industries in the 13th Five-Year Plan" and "The development plan of new material industry in the 13th Five-Year PlanThe new material industry system of DEAR air separation has been initially formed and the development situation is good. With the introduction of national strategic planning such as "The development plan of national strategic emerging industries in the 13th Five-Years Plan" and "The development plan of new material industry in the 13th Five-Years Plan", it has created a good policy environment for the development of new material industry. Recently, DEAR air separation cooperated with clients on the 1500/100 Y-type project of small air separation plant. The overall design of the project is reasonable, and the one-time drive is successful, and all the
