Some knowledge of air separation(2)

1.Why remove impurities during air separation. As the air cools, the frozen water and carbon dioxide are deposited in a cryogenic heat exchanger, a turbine expander, or a distillation tower, blocking passages, pipes, and valves. Acetylene accumulates in liquid oxygen and is in danger of explosion. Dust can wear away the running machinery. In order to ensure the long-term stable and reliable operation of air separation equipment, special purification equipment must be set up to remove these impurities. 2.How to judge whether the heat regeneration of molecular sieve is complete? Firstly, the gas pressure and flow required to heat the molecular sieve are required to meet the process requirements.Heating regeneration process can be judged by regeneration curve. “Cold blast peak”

Some knowledge of air separation(1)

1.What is reflux ratio?What effect does it have on rectification？ Reflux ratio refers to the ratio of the amount of liquid flowing down the rectification column to the amount of steam rising in the rectification column. When reflux ratio is large, nitrogen purity in gas phase is high and oxygen purity in liquid phase is low. When reflux ratio is small, nitrogen purity in gas phase is low and oxygen purity in liquid phase is high. 2.What are the causes of molecular sieve water inlet accidents? a.When the liquid level of the air cooling tower is higher than 3500mm, the water exceeds the height of the air inlet pipe, and a large amount of water enters the molecular sieve adsorber

The technology of Helium purification recycle plant

The common method of helium purification recycle plant is cryogenic and condensation. In addition, a lot of new technologies in the cryogenic field are also adopted in the plant development process, including vibration reduction of high pressure helium compressor, special welding technology of cryogenic and high-pressure copper pipelines, and cryogenic and high pressure flexible sealing technology, etc., to optimize products. On this basis, making a breakthrough in the purification technology through membrane separation method. A low-purity helium with a purity of 10% or more was purified to more than 99.5% and the recovery rate of system purification was more than 60%. Features of technology A new type of recycling plant for waste helium purification manufactured by Chinese enterprises monitoring the

Scope of application-helium

Helium is mainly used for the detection of leakage in medical and military refrigeration semiconductor pipelines, high-precision welding metal, manufacturing deep-sea diving photoelectronics, production of balloon borne scientific research and military, etc. 1.Nuclear magnetic resonance (cryogenic superconductivity) field Magnetic resonance imaging (MRI) uses the cryogenic superconducting magnet technology requires cooling liquid helium, according to the statistics, nuclear magnetic resonance (NMR) imaging accounted for 34% of the world’s dosage of helium, one of the biggest end use industry. Although demand for magnetic resonance imaging in developed countries is declining, but demand is still strong growth in developing countries, so as to keep the strong demand of liquid helium. 2.Refrigeration (home appliances) field Helium gas is mainly used for detecting the leakage

What does distillation mean?

For two substances of different boiling point (such as oxygen and nitrogen) compositing mixed solution, while after absorbing heat and partial evaporation, volatile composition nitrogen will evaporate more. Mixed steam releases heat and part of it condensates, while composition oxygen which is difficult to volatilize will condensate more. If you make saturated steam with higher temperature and saturated solution mixed, then steam gives off heat to saturated solution. After releasing heat, part of steam will condensate. Solution will absorb heat and part of it will evaporate. When partial steam’s condensation happens, due to oxygen condensates more, so the concentration of lower boiling point composition (nitrogen) in steam would be promoted. During partial evaporation of solution, owing to nitrogen evaporates more, the concentration of higher boiling point composition (oxygen) will be promoted. If after partial evaporation and partial condensation
