Problems with the height of the straight pipe section from the outlet of the distillation tower to the condenser
Thread Content
As shown in the figure, the tower diameter is 1000mm, the tower height is 13 meters, and the outlet pipeline at the top of the tower is DN45O. I would like to know if it is OK if the condenser is arranged at a height of 23 meters. Is it better to place it higher or lower?
There is no need to put it that high. A 12-meter platform is enough. Pay attention to the stress calculation of the heat pipe.
Spiral wound tube has no thermal effect
I guess the poster placed the condenser so high so that the follow-up process would be fully self-flowing. Haha, energy saving is no problem in principle.
It's possible, but why is it arranged so high? Isn't it a waste of pipelines? The price of DN450 pipe is not low either. . . Go down one level
How does the reflux tank transport discharge and reflux?
Consider throughput and process safety
I don’t know if this is internal or external reflux. Your diagram doesn’t show external reflux. If there is internal reflux, make it as short as possible so that the vapor phase can come over and condense in time. ； If it is an external return flow, the height must be considered. You can refer to the principles of chemical engineering, which is the pipe resistance and tower pressure that need to be overcome in order for the condensed liquid to flow back into the packing.
1. The gas phase at the top of the tower is in a saturated state. The longer the pipeline to the condenser, the more heat will be dissipated. It is possible that the material in the condenser will start to condense before it reaches the condenser, and will return to the tower, destroying the balance in the tower.； 2. The general design is that the elbow comes directly from the top of the tower, and the condenser is arranged at the lower part of the tower top.
