Liquid nitrogen plant
Product Description
1. Characteristics of the plant:
A. 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.
B. By using the pre-cooling system to cool the air with normal temp. Thus it makes the molecular sieve adsorbent in good condition.
C. 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.
D. By using a new construction of the evaporator-condenser to avoid the accumulation of C-H chemical compounds.
2. Liquid nitrogen generator plant:
3. Process Description
A. Air compression and pre-filter system: Air is compressed by screw compressor. Then part of free water and oil is removed by the following oil-water separator
B. Air pre-cooling purification system: After compression and water separation, air enters the pre-cooling unitand be pre-cooled. Then it enters into two stage of fine filter to further filter out water, oil and gas.
- c. Air purification system: After pre-cooling and purification, air enters into the molecular sieve purification system, Gaseous impurities such as the remaining water, carbon dioxide are removed by molecular sieve absorption
D. Distillation system: After pre-cooling and purification, basically, the air can be considered to be a mixture of oxygen and nitrogen. It then enters into the distillation system in the fractionating tower, after expansion refrigeration, distillation of liquefied; We can get the liquid product of 99.7% oxygen and 99.999% nitrogen

E. Liquid reserves pressurization system: Liquid oxygen and nitrogen products are sent into the cryogenic liquid storage tank for storage after coming out from the fractionation tower. They are pressured according to the user need through the liquid pump. After that they are directly bottle filled or sent to users after entering the air heated vaporizer for gasification.

Our company was established in 2001 and is located in the Hi-tech Development Zone of Fuyang City, Hangzhou, adjacent to 320 National Road and Fuchun River, with convenient transportation. Our company has been committed to producing small-sized and medium-sized air separation equipment until now. After several years of elaborate operation, our company has become a professional manufacturer integrating the design, production and installation of complete sets of small-sized and medium-sized air separation equipment.
In 2001, the first set of full-low-pressure and positive flow rate expansion gas equipment was developed independently in China. Our company has kept making innovation on different categories of products in the field, and applied the technology to other areas. In 2007, our company broke through the traditional concept in gas equipment field, and developed the first set of high-purity and high-pressure hydrogen preparation device, cooperating with research institutions. In the early period of 2008, cooperating with Beijing Shijixing Petrochemical Equipment Ltd., our company developed the oil and vapor recovery equipment for petrochemical industry. We are the only company applying the air separation technology in the oil storage "green energy" project in petrochemical industry. In 2009, cooperating with Tianjin University, for the first time, our company applied the cryogenic distillation technology to chemical material purification. The products turned to reach the purity of 99.999%, which was highly praised by users.
Our products have been sold across the country. A lot of plants have been put into operation in foreign markets, such as India, Africa, Southeast Asia, the Middle East, Eastern Europe, etc. With the increase of output every year, our company has become a high-tech air separation equipment manufacturer, enjoying a certain reputation in air separation field.
Our company insists on the spirit of "customer supreme, technology precede, quality first, excellent service", and is dedicated to providing customers at home and abroad with advanced, economical, safe and reliable products and service. We warmly welcome your presence and guidance.
