What safety problems should be paid attention to when using regenerative electric heater in air separation plant
Jan 09, 2023
Author: DEAR AST

As an electrical equipment, the electric heater shall be operated with attention to personal safety and equipment safety. Specifically:

1) Operate in strict accordance with the operating procedures. During heating, ventilation shall be conducted before power on, and pay close attention to whether the gas flow is normal. When the heating is stopped, the power shall be cut off first and then the gas shall be cut off. It is strictly forbidden to power on when there is no ventilation or the air volume is very small.

2) In case of automatic tripping or fuse fusing due to circuit failure, or temperature does not rise after power on, ask electricians to check and repair;

3) The temperature control instrument shall be calibrated regularly to ensure its sensitivity and accuracy. The furnace temperature shall not be out of control due to instrument failure. The relay shall be cleaned and dusted regularly to avoid moisture;

4) The non charged metal parts (shell, support, etc.) of the electric furnace shall be reliably grounded;

5) Pay attention not to make the temperature of the furnace shell too high (the temperature rise exceeds 60 ℃), so as to avoid aging or insulation damage of the power line;

6) The insulation resistance of the electric furnace that has not been used for a long time must be checked before use;

7) Operators shall receive training on safe use of electricity.

The DEAR Air Separation Engineering Technology Team has experts and professional technicians who have been engaged in the construction of air separation projects for a long time to ensure that each link is implemented in place and handled carefully, so that customers can rest assured and satisfied.

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
