Braking method of turbine expander

Braking method of turbine expander
Feb 20, 2024
Author: DEAR AST

The gas works externally through the expander. In the process of generating cooling capacity, there must be braking to consume this part of work. There are three braking methods: generator braking, fan braking and booster braking. The generator braking can recover the work done by the expander, but the power grid fault will also affect the work of the expander, and the equipment investment is large; The fan braking equipment is simple and easy to operate, but the noise is large, and all the work done by the expander is wasted;; The booster brake absorbs the power of the expander, and at the same time, it can increase the unit cooling capacity of the expander, reduce the expansion air volume, and is conducive to the oxygen extraction rate.

DEAR air separation enterprise intelligent innovation team, in order to improve the core competitiveness of the enterprise, create a scientific and technological enterprise, create a high-quality and energy-saving air separation equipment, and closely follow the development direction of the world manufacturing industry, plans to invest more than 30 million yuan to cooperate with Zhengzhou Kehui technology company, Shenzhen Gugao Motion Control Research Institute, Guyuan special robot company, Shandong Shuibo welding and cutting equipment manufacturing company The Artificial Intelligence Research Institute of Hefei University of technology and other units cooperated with scientific research institutions to create an air separation equipment production line with intelligent flexible production, and a modern intelligent air separation demonstration enterprise integrating intelligent management and operation, remote equipment monitoring and operation.

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
