Main power of air-separation industry—steel industry
Monday, 20 November 2017
steel industry is the main power for the development of air-separation industry which lead air-separation industry into its golden time. According to the oxygen consumption of steel industry, during the process in the blast furnace, converter, continuous casting and rolling of the traditional process, the oxygen consumption of per ton steel is about 120 Nm3/h. Every year millions of tons of steel production scale need match air separation plants with the capacity of 15000 Nm3/h, when not in oxygen-enriched blast furnace can be reduced to 10000 Nm3/h. When using COREX puddling technology, electric converter, continuous casting and rolling steel are installed, the capacity of the spare parts required for each million tons of steel shall be increased to 50,000 Nm3/h,
The application of oxygen, nitrogen and argon in steel industry
Tuesday, 14 November 2017
Oxygen The processes of puddling and steel-making need much oxygen. Oxygen top blowing converter steel-making Blast furnace rich oxygen blast Electric furnace steel-making COREX steel-making Steel processing, continuous casting flame cutting, cleaning and so on, tonnage oxygen consumption is 10 ~ 12Nm3 Nitrogen Nitrogen is mainly used in metallurgical works for sealing gas, conveying gas, protecting gas, stirring gas, blowing gas, instrument gas, etc. At present, the consumption ratio of oxygen and nitrogen in metallurgical plants is about 1:1, and the nitrogen consumption is also increasing. The nitrogen production should be properly reserved on design. Argon Argon is used for stainless steel smelting, steel ladle argon lowing, conticaster steel ladle and tundish nozzle sealing, protecting gas, etc. At present, the
The dependence relationship between steel industry and air separation industry
Tuesday, 07 November 2017
Interdependence and mutual promotion is the relationship between steel industry and air-separation industry. Growth of steel industry leads the development of gas industry and the development of gas industry promotes steel industry, which is similar to the closed acting force and counter-acting force. New technologies appeared in steel industry require new quantity, quality and technology from gas industry now and again. To meet the continuous demands of steel industry, gas industry has developed itself and promoted the steel industry forward, which can be noticed when looking back the development of domestic and overseas air-separation industry. Get a clear understanding of the relationship between the two industries is extremely important to gas industry, which can remind us to focus the development
Process description of liquid air separation plant
Friday, 27 October 2017
After impurity removal, air is taken by compressor and compressed to ~1.1MPa. After cooling down, harmful components, such as moisture, CO2, C2H2 are removed by purifying system. After purification, compressed air is cooled down by the main heat exchanger and cold refrigerator, and sent to rectification column for rectification. Through sub-cooler, liquid air, liquid waste nitrogen and liquid pure nitrogen are sent to upper column for secondary rectification. In upper column, liquid oxygen at 99.6% is obtained at bottom, which is delivered out of cold box via sub-cooling as product. Waste nitrogen is drawn from top of upper column. Through heat exchanger, it is expanded to provide coldness to the whole system. After warming up, it is delivered out of cold box and divided into 2 streams. First
Process description of small-scale inner compression air separation plant
Tuesday, 24 October 2017
Eliminated from mechanical impurity by the air filter, the required amount of process air is compressed by air compressor to rated pressure. Afterwards, it goes into water-cooling tower for cleaning and pre-cooling. The removal of harmful components, such as moisture, CO2, C2H2 are carried out by activated alumina and molecule sieve in molecule sieve purifier, which will automatically alternate. After purification, compressed air goes into main heat exchanger, and cooled down to its dew point temperature. Afterwards, it goes to lower column for primary rectification. In lower column, gas nitrogen is got the top of lower column, and then condensed into liquid nitrogen in evaporator-condenser. Part of liquid nitrogen is sent back to lower column as reflux. Balance liquid nitrogen and
Process description of gas air separation plant
Friday, 20 October 2017
Eliminated from mechanical impurity by the air filter, the required amount of process air is compressed by centrifugal air compressor to ~0.5MPa. Afterwards, it goes into water-cooling tower for cleaning and pre-cooling. The removal of harmful components, such as moisture, CO2, C2H2 are carried out by activated alumina and molecule sieve in molecule sieve purifier, which will automatically alternate. After purification, small stream of compressed air is compressed secondarily by booster end of turbine. Through cooling via water cooler, it goes into main heat exchanger for secondary cooling. Then it is drawn from middle part of heat exchanger to expander of turbine. Afterwards, expanded air is sent to upper column for rectification. After purification, large stream of compressed air is cooled
