Principles of air precooling

The temperature of the air compressed by the air turbine compressor rises to more than 80 ℃, which leads to the failure of the subsequent adsorption heat transfer link. The air inlet temperature of the air separation unit can be effectively reduced by setting the air precooling system.

 

Electrostatic deposition: electrostatic makes the dust change its moving track and collide with obstacles. Electrostatic force participates in the work of adhesion.

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

Answer: the default unit gauge pressure is MPa (g), and the mainstream is cryogenic full low pressure external compression process. Design pressure of conventional energy-saving models in the industry: 0.50~0.55 MPa (g); The lower limit of stability of ordinary process is about 0.45 MPa (g). In general, it is not recommended to be lower than 0.42 MPa (g) for a long time in the conventional scheme. If the pressure is too low, there will be risks such as poor heat exchange in the precooling tower, insufficient purification of molecular sieve, difficult to balance the cooling capacity, and the air compressor close to the surge area. The internal compressed air is distributed with a booster. The main air compressor is mostly 0.55~0.65 MPa (g), and the lower limit is mostly 0.50 MPa (g), which is difficult to achieve below 0.45MPa (g). Deere air separation ultra-low discharge pressure patented energy-saving external compression air separation, through the collaborative optimization of the w
