Standardization of cryogenic air separation equipment

Answer: 10000nm ³/h is a medium-sized air separation unit. The positioning of each company varies greatly, and there is no absolute best. Deer air separation (deep) is preferred according to the demands of the project 1. Positioning: 1000~50000 air separation home, focusing on energy conservation+digital intelligence integration, which is very suitable for gas Island, metallurgy and new material gas supply in the park 2. Deere air separation advantage: ① The track is focused. There are sufficient 10000 level production cases, and mature achievements in external compression, all liquid and argon processes; ② Complete hardware energy-saving scheme: 8h long-term high-efficiency molecular sieve, waste heat recycling of air compressor, high-efficiency structured packing+high-precision distributor, high extraction rate distillation, stable comprehensive power consumption of 0.44~0.48 kwh/nm ³ o ɑ under the same working condition, saving energy by 10%~15% compared with traditional air separat

Pressure test before valve installation 1. In the warranty period, those with the certification and the sealing surface is intact can no longer conduct the strength test alone, but only the air tightness test can be taken before installation. 2. Within the warranty period, it has the certificate, and its sealing surface has defects such as corrosion and damage. After treatment, it must carry out the air tightness test. 3. Outside the warranty period, those with certification and intact sealing surface shall be subject to air tightness test before installation. 4. For valves that need to be degreased and disassembled on site, air tightness test shall be conducted separately before installation. 5. The safety valve shall be sent to the local quality inspection department of the project for verification before the end of installation and commissioning.
