Procurement of air separation equipment

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...

The load adjustment range of low pressure small air separation unit is related to the adjustment performance of the raw material compressor, the adjustment performance of the expander, the structural characteristics of the distillation tower and other factors. At present there are imported guide vane of the turbine air compressor flow adjustment range in 75-100%; adjustable nozzle of the turbine expander adjustment range can be in 65-100%. When oxygen is rich and the need to reduce oxygen produc...
