Container residence time
Thread Content
Regarding the condensate separation tanks, where gas makes up 5% to 10% of the mixture: 1. For buffering purposes, the gas phase goes into the compressor or the steam pipeline system, while the liquid phase goes into the tank; 2. Also for buffering purposes, the gas phase goes into the compressor, and the liquid phase goes into a pump. For these two types of tanks, I have designed a residence time for the liquid phase of 1.5 minutes in case 1, and 15 minutes in case 2. Now the boss wants to reduce this residence time to 1–2 minutes in order to shorten the time it takes for the liquid to stay in the tank, and this is to be achieved by using control valves. I think this design will lead to many problems. I was wondering, experts, what is the minimum appropriate duration for a stay? If you help, there will be a generous reward.
There is a conflict between residence time and equipment investment; the residence time must take into account the processing time required when dealing with failures. If the compressor can tolerate liquid presence, 2 minutes is sufficient. A high degree of automation can save the buffer time required for normal operations.
