1. The requirements of molecular sieve adsorber, electric heater and other equipment in place are the same as those of air cooling column of pre cooling system. 2. Process piping shall be constructed in strict accordance with relevant specifications and design and construction drawings. 3. The air tightness test shall be conducted before the valve is installed, and the test pressure and inspection standard shall be carried out according to the technical requirements of corresponding valves. 4. Pay attention to the direction of switch valve installation. V1201, V1202, V1207 and V1208 are front mounted valves, while V1203, V1204, V1205 and V1206 are reverse mounted valves. When the switch valve is installed, its shaft should be in a horizontal position, and the flange bolts should be evenly cross tightened. 5. The pipeline of pressure equalizing valve V1209 should have compensating bend.

Users reported that the on-line analyzer of a 30000 grade air separation plant showed that the outlet CO₂of the molecular sieve suddenly increased from the normal value of 0.43×10-6 to 120×10-6, and the temperature difference in the expansion air channel entering the two high-pressure plate fin heat exchangers began to expand. At the same time, the temperature in front of expander also decreased from - 105°C to - 132°C with liquid entrainment. After receiving the user's notice, DEAR air separation sent technical personnel to the site for observation and detection. It was found that the location of the self-cleaning filter of the equipment was close to the chemical boundary area. When the wind direction was in the downwind direction of the chemical industry boundary area, the phenomenon that the concentration of CO₂ in the air at the inlet of the self-cleaning filter of the air compressor exceeded the standard. In view of this phenomenon, the following opinions are given: 1. Sh
