Italy Customer visiting and investing plant on site

From March 19th to March 24th in 2018, The Italy Italy Customer came to visist XLA. During this trip, They  visited Yi chuan &Xishui Plant site in China. They spoke highly for the two plants。They  visited the workshop in XLA. They approve the air separation plant of XLA. They considered the technology from design to manufacturing of air separation plant by XLA is vey mature and XLA also accumulated a lot of experience in this industry, which will get a higher level in the air separation industry.

How much do you know about the air separation unit operation control system?

The air separation unit adopts cryogenic technology, which uses oxygen and nitrogen gas to separate gas at different boiling point under the same pressure to extract oxygen, nitrogen and other gas components in the air. At present, the main air separation processes are divided into internal compression processes and external compression processes. Most of the newly designed air separation units use the DCS control system. The DCS control system better realizes the chain protection and anti-surge control of air compressors, the sequence control of molecular sieve systems, and other conventional controls. The implementation of the DCS system has smoothed the operation of the equipment to some extent, and improved the control level of the equipment. In order to achieve automatic variable

The definition of LNG

The definition of LNG Liquid natural gas (LNG) is natural gas (predominantly methane, CH4, with some mixture of ethane C2H6) that has been converted to liquid form for ease and safety of non-pressurized storage or transport. It takes up about 1/600th the volume of natural gas in the gaseous state (at standard conditions for temperature and pressure). It is odorless, colorless, non-toxic and non-corrosive. Hazards include flammability after vaporization into a gaseous state, freezing and asphyxia. The liquefaction process involves removal of certain components, such as dust, acid gases, helium, water, and heavy hydrocarbons, which could cause difficulty downstream. The natural gas is then condensed into a liquid at close to atmospheric pressure by cooling it to approximately −162 °C

Main power of air-separation industry—steel industry

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

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

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

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
