The influence of argon production in air separation equipment on the liquid air inlet

The molecular sieve used in oxygen generators is the zeolite molecular sieve. It is a crystalline silica and aluminate polyhydric compound. Molecular sieves have a uniform pore size and their main function is to sieve molecules. There are three main types of molecular sieves: A, X and Y. The 13X molecular sieve is the only adsorbent currently used in liquid air separation plants. Any molecules that can be adsorbed on 3A, 4A and 5A molecular sieves can be adsorbed by 13X molecular sieves. It is c...

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.
