 Maximum allowable concentration: China, were not set standards; US TVL-TWA, ACGIH asphyxiating gas. Monitoring Methods: Not available engineering controls: closed operation. Provide good natural ventilation. Respiratory protection: general need special protection. But when the oxygen concentration in workplace air is less than 18%, must wear air respirators, oxygen respirator mask or long pipe. Eye protection: general need special protection. Contact with liquid argon should wear masks. Physical protection: wear protective clothing. Cryogenic liquid argon workplace should wear winter clothes. Hand Protection: Wear protective gloves general operations. Other precautions: Avoid inhalation of high concentrations. Into the tank, or other restrictive space of high concentration operations, someone custody argon distribution and liquid air, liquid nitrogen purity about the next column, when the higher purity industrial nitrogen, argon, liquid nitrogen argon concentration smaller. In order to increase the extraction rate of argon, nitrogen purity must be increased: in ensuring the production of oxygen, oxygen purity unchanged purity argon gas industry, due to lower liquid air purity, increase nitrogen purity argon gas industry standards, so that the tower fine stripping section load is reduced, nitrogen, nitrogen pollution purity will be improved, reducing the amount of argon to bring out the extraction rate of argon increased accordingly. Given the above analysis, the adjustment process in ASU's main tower, we refocused the purity nitrogen pollution under the tower, proper sewage off small nitrogen, pure nitrogen valve, so pure oxygenated liquid nitrogen to 3 to 5 × 10-6, sewage nitrogen containing oxygen maintained at 2% to 2.5%, nitrogen pollution rose to 98 percent purity, liquid air purity is maintained at 32% ~ 34%, and by controlling the oxygen purity, oxygen-argon fraction stable at 89% to 90% of the group Leeport | Industrial argon Suppliers | Argon gas is provided by HSBC Group.
