Installation of the air pre-cooling system in small air separation unit

Mar 16, 2022

Author: DEAR AST

(1) Air cooling tower is a pressure vessel, the site is strictly prohibited on the tower body fire.

(2) installation requirements: verticality <1/1000, the full length of the range shall not exceed 10mm.

(3) loading material before, clear the tower debris and check the tower pieces of fasteners, confirm no loose, off.

(4) bare cold before, air-cooled tower, water-cooled tower at the top of the screen mist trap again check, confirm no gap, no loose.

(5) filler into the tower before, need to check the filler specifications, apparent quality, strength, quantity, etc. to confirm the correct. If the filler can not be filled immediately, need to be stored in the warehouse, should not be long-term open-air placement.

(6) filler installation: filler shall not be mixed, shall not contact grease. Can not be directly from the top of the tower directly into, should be from different heights of the hole for layering filling.

(7) test pressure: after installation, to work pressure on the system for gas tightness test, maintain pressure time shall not be less than 2 hours, shall not leak.

I want to make a small cryogenic air separation unit with argon. What manufacturers' technology is relatively mature, and what are the key points of model selection?

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

How much can the pressure of air compressor be reduced for energy-saving air separation equipment?

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
