Industrial gas is known as the “blood” of industry, and gas consumption is closely related with the speed of economic development. Air separation equipment, one of the core equipment in the industrial field, is widely used to produce high-purity gas and is interdependent with industrial gas.
The main constituents in the air are oxygen, nitrogen and argon, all existing as molecules. The most commonly used method is cryogenic separation. Firstly, compressing and cooling the air to liquidation, and then separate it in a rectification column since the difference of boiling point of each component. For example, when liquid air is boiling, nitrogen (boiling point: -196 deg C), which is easier to volatilize, will be vaporized first, and oxygen will be vaporized later (boiling point:-183 deg C). The whole process includes compression, purification, heat exchange, liquefaction, refrigeration and rectification. (As shown below)
Xinglu Air Separation is committed to developing convenient and reliable equipment that saves energy and reduces consumption with 65 invention patents and 37 utility model patents, and has continuously made outstanding contributions in reducing unit energy consumption. For example, patent number ZL200610097738.X, it’s an air separation method and device that is able to produce 10% more liquid nitrogen, while reducing the power consumption of per unit product and further optimize the cost performance.
The following video is a liquid nitrogen equipment designed by our company for one of Russian customers, able to operate at -54 ℃, and is currently in the installation and commissioning stage.
