| Abstract: |
| Air cooler for regeneration gas is a key equipment to cool the high temperature rich regeneration gas of molecular sieve dehydration regeneration gas system. However, the air cooler leaks frequently due to the great vibration, material corrosion, unreasonable structure design and manufacturing defect on-site operation, which causes major impact for the continuous and stable operation of molecular sieve dehydration device. The optimization scheme has been proposed through analyzing the technological process for regeneration gas in this paper. Besides, the possibility of the equipment, pipelines and valves can sustain high temperature rich regeneration gas in new technological process has been reviewed. The optimized new technological process can realize maintenance of the equipment dispense with suspending production. It has great significance for improving the continuous and stable operation of the device and completing the task of guaranteeing supply in winter. |
