Note: 1. All pressures which are not specially defined below are the gauge pressures.
2. Nm3 /h is defined as the volume at 0℃, 101.3kPa(A);
3. The liquid output is calculated from data of gas, and the pressure is calculated with 0 meter high at outlet of cold box.
Process Description:
The proposed Air Separation Plant employs a process in which air is purified by molecular sieve at normal temperature, high/low temperature booster expansion turbine is used to produce refrigerating capacity, medium pressure nitrogen for circulation, structural packing is applied and argon is extracted through full rectification.
Applications:
1. Basic oxygen steelmaking;
2. The complete set of air separation plant and accessory equipments are the necessary important technical equipments for the basic industry (metallurgy, chemical industry, etc.) of national economy and tech fields (aerospace aviation, nuclear submarine, etc.).
3. Used for inerting storage tanks of ships and tanks for petroleum products, or for protecting edible oil product from oxidation.
4.It is appropriate for the industries and fields such as chemical industry, petroleum, electric power, steel, medical treatment, food, electronic, construction, print and automobile, etc.
5. Coal gasification projects;
Competitive Advantage:
1. The fractionating column employs the advantages of high extraction efficiency of oxygen and argon with low power consumption. The control system for the ASP is advanced, reliable and cost-effective.
2.In order to guarantee the optimum technical and economical targets, the advanced software for performance calculation is used to calculate and analyze the optimized process while the program developed by Hangyang itself and verified in many air separation plants is used for rectification calculation.
3.. We offer a wide range of services including design, manufacturing, installation, commissioning, personnel training and after-sales serivce.
4. The proposed air separation plant is designed for long, stable and reliable running, economization of energy, convenient operation and maintenance and the up-to-date international advanced air separation technology is incorporated.
5. The control system for the ASP is advanced, reliable and cost-effective.
