What factors are related to the load regulation range of low-pressure air separation equipment

Oct 07, 2023

Author: DEAR AST

The load regulation range of low-pressure air separation equipment is related to factors such as the regulation performance of the raw material air compressor, the regulation performance of the expander, and the structural characteristics of the distillation tower.

At present, the flow regulation range of turbine air compressors with imported guide vanes is between 75% and 100%; The adjustment range of a turbine expander with adjustable nozzles can be between 65% and 100%. The key is the adjustment margin of the distillation tower. At present, the load adjustment range of distillation columns using regular packing can reach 50% to 100%, while the best adjustment range for traditional sieve plate columns is 70% to 100%. Any lower load may result in liquid leakage due to the low speed of steam passing through the sieve holes.

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).
