The plate spacing of the sieve tray tower of the air separation unit is related to the tower height and separation effect. The following two factors should be considered when determining the plate spacing. It is necessary to ensure that the gas and liquid can have sufficient contact area and separation distance, avoid entrainment of mist during work, and ensure that the liquid can flow smoothly from the previous tray to the next tray, overcome the resistance of overflow bucket, and flow smoothly without flooding. However, when meeting the above requirements, the spacing shall be minimized to reduce the tower height.
The research and development of DEAR air separation unattended technology will deeply combine the air separation process with the Internet of Things remote centralized control and unattended control technology, which will effectively promote the continuous development of the air separation gas industry. The research and development of unattended air separation equipment will realize: 1. PLC or DCS will be used to control the whole process of air separation equipment automatically; 2. Realize the unattended work in the air separation equipment room; 3. It can greatly reduce the cost of on-site supervisors; 4. Reduce possible production accidents caused by misoperation; 5. Save production and operation costs; 6. Improve the quality and efficiency of gas supply; 7. Ensure the safe production of all work. In order to save operating costs and social resources, Deer Air Separation will actively develop unattended air separation equipment.
