Nitrogen—Industry salt

1.Nitrogen-filled packaging, nitrogen filling bulbs.Chemical properties (using chemical properties is stable, normal temperature is very difficult to react with other material “) food, canned, fruit and etc.usually use nitrogen for corrosion protection.The nitrogen filling in a light bulb, can prevent the tungsten oxide and slow down the utilization rate of tungsten filament, prolong the bulb’s service life . 2.Chemical synthesis is important raw materials of synthetic fiber (nylon, acrylic), synthetic resin, synthetic rubber and other , also can produce fertilizer. 3.Production car tyres, nitrogen filling tyre can improve the stability and comfort during driving, preventing blowout and grinding line due to deficency , prolong the service life of tires, reduce fuel consumption, protect the environment. 4.Used as shielding gas, normally, Nitrogen’s chemical nature doesn’t very lively, so it is

Application of gas hydrogen in petrochemical industry

1) A 1000t/d scale ammonia plant is used as a raw material gas for ammonia, methanol and petroleum refining. It need 336 cubic meters for per ton of ammonia, and if the ammonia is produced on a large scale. The main cost is comes from the hydrogen. A 2500t/d scale methanol plant, each production of 1 ton of methanol needs hydrogen 560 cubic meters; Hydrogen is also the organic hydrogenation reaction feed gas. 2) Synthesis of organic compounds Hydrogen and carbon monoxide synthesis compounds  to a variety of organic compounds , such as ethylene glycol synthesis, synthesis of polymethanes, alcohol homologous reaction,etc.

Application of gas nitrogen in Coal chemical industry

In the small water gas production of ammonia plant, the proportion of nitrogen to hydrogen ratio is table after adding the nitrogen, which smooths the operation and reduce  the consumption of synthetic ammonia; In addition, it also use the refined nitrogen (99.99%) to protect the catalyst; With pure liquid nitrogen washing refined Hydrogen and nitrogen mixture, so that the inert gas (methane and hydrogen) is extremely small, the contact of carbon monoxide and oxygen are no more than 20PPm. The consumption of nitrogen wash and nitrogen are about 750m3/t ammonia. Oxygen  is functioned as  the  evaporator of pulverized coal or heavy oil, nitrogen involved in the synthesis and function as  raw materials for gas, and be the safety gas of

Application of gas nitrogen in nitrogen fertilizer industry

Nitrogen is the main raw material of nitrogen fertilizer industry, such as ammonium nitrate with 36% nitrogen , ammonium sulfate n with 21% nitrogen, urea  with 46.7% nitrogen. Nitrogen is also used to replace air or gas in pipelines and containers before the start of production of the nitrogen fertilizer plant or after overhaul to ensure safe operation. Lime nitrogen is a kind of chemical nitrogen fertilizer, 1 ton of lime nitrogen will consume nitrogen 300~500m3; nitrogen is mainly used for ammonia synthesis, ammonia is the main raw material of chemical fertilizer industry and basic organic chemical industry.

Application of gas nitrogen in chemical factory

In the chemical plant, nitrogen is mainly for the protection of gas, ventilation and washing gas, to ensure safe production. Such as polypropylene production, it need to use pure nitrogen (99.99%) functioning as the protection of gas, replacement gas. High purity nitrogen is a vital source of chemical fiber production. Such as Liaoyang Petrochemical Plant has three sets of 3000 m 3 / hour high purity nitrogen device;Synthetic leather factory also use high purity nitrogen to do protection, such as Yantai synthetic leather factory has a 1000m3/hour high purity nitrogen device. Forest chemical plants also use nitrogen, as a sensitive adhesive coating, rosin, resin and other production process of protective gas. It can be said that the chemical plant has a big

Core equipment of air separation plant—fractional column

Fractional column is the general name for the whole set of equipment consisting of cold box, main heat exchanger, evaporator-condenser, sub-cooler, rectification column, turbine, cryogenic valves, pipes and meter tubes. Cooling, liquefaction and separation of process air, expansion and warm-up of oxygen-rich air and warm-up of product gas are all carried out inside the fractionation column. The rectification column is made of aluminum, and is the highest equipment inside the cold box. It is the class I pressure vessel. The rectification column is installed with packing. Air separation of is achieved in the rectification column. Through all kinds of I/O nozzles, the rectification column is connected with heat exchanger, vaporizer-condenser etc unit efficiently, to realize the liquefaction, separation of air, sub-cooling of liquid air and gas warm-up.

Technical advantages of plants whose capacity are smaller than 350Nm3/hO2

Technical advantages of complete low pressure plant KDON-80/40; This plant is the smallest ASU with complete low pressureplant in China, which was initially developed by XLA in 1997. This plant is a revolutionary promotion for process of small plants. It took place of traditional KZON-50/100 as soon as its successful commissioning. Specific power consumption of KDON-80/40 is even 50% lower than that of KZON-50/100. Titled as “New and High tech product of Jiangsu Province”in 2003; Designed and manufactured with several know-how technologies; Simple operation and maintenance, cost-effective.   Technical advantages of complete low pressure plant KDON-170/100; This plant was developed in 2002, working on same process with KDON-80/40. It took place of traditional KZON-50/100. Specific power consumption of KDON-170/100 is 50% lower
