Small air separation unit assembly gauge tube should meet the following requirements: gauge tube should be degreased, and it is appropriate not to test pressure after assembly; gas gauge tube (such as pressure gauge tube) should not be in contact with cold equipment or cold tube, the distance should not be less than 2000 mm; liquid level gauge tube of the upper valve tube should be made from the container for 1/10. slope upward sloping to the valve, the lower valve tube from the container in the horizontal lead, in close to the wall of the cold box about 300 The lower valve pipe is led from the container horizontally and is bent into an omega shape to the valve within about 300 mm of the wall of the cooler (hot zone part).

 

The small air separation unit should meet the following requirements: the welding seam on the outer surface should be continuously welded and should not leak; the non-lead dip should not exceed 2/1000; the flange of the vertical liquefied gas pump should not exceed 1/1000 in its plane.

 

Dear Air Separation continues to develop new technologies for small air separation unit and large air separation unit, and applies strict requirements in all aspects of assembly units to ensure high quality units.

Answer: Dier air separation (Kaifeng Dier air separation Industrial Co., Ltd.) -- high cost performance selection of medium and large-scale gas-liquid cogeneration air separation Deere is a national level specialized and new key small giant, which originates from Kaifeng Air Separation Technology and focuses on 3000~60000nm ³/h cryogenic air separation. Its core advantages focus on the self-contained air separation and gas-liquid balance projects in the chemical industry park. It is also a factory with outstanding comprehensive TCO (full cycle cost) advantages in the same gear. Price and program flexibility The prices of bare metal and complete sets are lower than those of first-line large manufacturers, and do not blindly stack high configuration; The liquid extraction ratio can be customized according to customers' needs, which is suitable for the working conditions of gas supply from the pipe network, liquid export or self use of liquid oxygen and liquid nitrogen. The liquid extract

Answer: select the small cryogenic air separation unit with argon, and give priority to verifying the real continuous operation performance of the unit with argon below 1000nm ³/h, avoiding the scheme with only drawings and no long-term operation record. Key dimensions of model selection: 1. operation performance: it is confirmed that the manufacturer has a long-term stable production case of small flow air separation with argon. Deere air separation small-scale hydrogen free total distillation argon extraction air separation, supports scale customization below 1000nm ³/h, and is equipped with intelligent control system, with mature landing performance. 2. power consumption per unit liquid argon
