    As we all know, air separation plant performance guarantee, the more difficult is the product of argon in preparation.
    Since the boiling point between argon oxygen, nitrogen, and difficulty of separation too large, the adjustment variable conditions adjustable load space too small, crude argon column for the establishment of the status of the main tower of the conditions require high nitrogen Cypriots And a series of small temperature range of objective factors, makes the whole system of argon distillation technology have a certain degree of difficulty.
    At present, domestic air separation industries and factories used in air separation process is basically in line, the entire low-voltage Zeolites are used pre-purification, supercharged turbine expansion, the entire distillation of new technologies such as argon. ASU in the key equipment such as: on the tower, crude argon column, refined argon column adopt a structured packing tower technology. It should be said that technically the manufacturers are basically similar.
    However, the manufacturers of air separation plant in a reliable and stable operation, in the performance guarantee, in particular argon products from different areas, and so on.
    Many have been running the air separation equipment, is often oxygen, nitrogen products can be extracted standards, but the system has not always argon system for normal operation, as the main cause for argon after the unstable condition so that users had to stop the - Argon system. To the final acceptance of the equipment left a regret, but also makes the whole system of argon distillation of the reliability of this advanced technology suffered a Bubaizhiyuan.
    So many users (especially for argon there is a demand of users) tend to argon system performance evaluation factories directly to the technical strength and product quality.
    Kaifeng Group of the Yellow River air separation equipment in order to improve the overall performance, particularly in the preparation of argon products, to ensure system-wide distillation argon for the reliable operation of the subject, conducted technical discussions, and the establishment of a chief engineer for the head To the old and new professional and technical personnel, technical staff, technicians and other workers of the main topics of research group.
    In summing up my company an air separation plant operating experience at the same time, collect a lot of air operations at the scene actual data, with the design and manufacture of equipment in the process of comprehensive analysis of state quality control measures. Argon find a solution for products shipped difficult to control the process. From the following aspects of our strict control to ensure the smooth running equipment:
    1, the use of ASPEN accurate simulation software to determine the optimum process and parameters.
    2, the focus on the tower determine the location of the exhaust fraction of argon, and to improve the internal structure of the exhaust mouth, to ensure that the argon fraction of the exhaust quality and stability.
    3, the condensation on the evaporator (the main cold, crude argon condensate, refined argon condensing) heat, the structural design of strict control. In particular, the design of the structure be improved to meet the requirements of state regulation.
    4, use of company-specific tower design and manufacturing technology, strict control tower, under the tower, crude argon column, refined argon column of manufacturing quality. Especially the tower of the manufacturing quality and assembly quality. To ensure that the process of distillation not offset.
    5, to accurately determine the reasonable amount of liquid cycle to ensure that the crude argon column stable condition.
    6, Ar-established system is simple and reasonable regulation control methods.
    7, carefully selected by the system argon system related to various types of valves, Orifice, Analyzer, regulating agencies. Measures to ensure the accuracy of regulation.
    8, to improve the design of the pipeline preparation methods. To ensure that the cold gas-liquid pipeline under the stress of compensation.
    I am in the above areas, from design to the source the beginning of each of the manufacturing process, strict quality control processes, constant practice and improve, improve, finally received the good results.
    Our company developed the design and manufacture air separation plant: KDON-3800/4000 type, KDON-4500/4500-KDON-6000/6000 type, KDON-10000/10000 type, KDON-12000/12000 type, KDON-15000/15000 Type, the above models of argon systems have been shipped to normal. Liquid argon yield and purity of the products are designed to achieve the targets, and the stable operation of the user site. Especially in 2006 has so far for users of the six sets of KDON-6000/6000 air separation plant is a successful drive, oxygen, nitrogen and argon products meet design specifications and put into industrial operation, the system argon equipment was put into operation 100 %.

    Practice has proved that our system of argon, improve and enhance the approach is correct, the measures taken is a scientific and reasonable and effective. Technology companies are also improving in the course of the Yellow River has gradually formed a sub-group characteristics of the air fractionating tower manufacturing technology and quality control methods. In large and medium-sized companies ASU distillation system-wide Argon has been a breakthrough in our distress, "Ar-hard" bottleneck.
    "Reputation first, quality and reliable" and "perfect technology, better" and "prompt delivery, first-class quality, well-managed, courteous service"; "contract-period, re-credit quality," Companies in the room covered with a user sent a face full of praises from the words of the pennants, the vast number of users of Kaifeng Group of the Yellow River in an air separation technology, quality, service, reputation, to make unremitting efforts for their highly valued.
    The market is fair, a good supporting performance of the enterprise development. The user groups more and more repeat customers, a user at the same time the company I used three sets of four sets of air separation plant products have been common example is not fresh, the company showed a steady increase in orders trend.
    Since the upgrade product quality, equipment performance with that customer satisfaction, the company contracts good project implementation, the funds back to Long smoothly, the company also has substantially increased economic efficiency, air separation Kaifeng Group of the Yellow River into a development Virtuous circle.
