Dehydration issue behind the machine
Thread Content
Molecular sieve dehydration is used for post-compressor dehydration. The questions are as follows: 1. How is molecular sieve drying and regeneration carried out? 2. During switching, the exhaust gas pressure fluctuates, resulting in an increased instantaneous evaporation rate in the lower column; this may lead to an empty column or material accumulation? How can these problems be avoided
1. How is molecular sieve drying and regeneration carried out? Dehydration was not considered during design; it can be dried and dehydrated using negative pressure or vacuum ； 2. During switching, the exhaust gas pressure fluctuates, resulting in an increased instantaneous evaporation rate in the lower column; this may lead to an empty column or material accumulation? How can these problems be avoided? After dehydration and compression, when the gas condenses, isn’t there something like a buffer tank that can prevent fluctuations in the low-pressure tower? ； As long as the low tower stops fluctuating, the exhaust pressure should stabilize.
