Let’s discuss the design of the condenser for vacuum distillation towers! The absolute pressure in my distillation tower is 4 kPa. The diameter of the condenser, as calculated, is 1400 mm; steam flows on the shell side. The diameter of the pipe running from the top of the distillation tower to the condenser is 800 mm. Is it appropriate to have a pipe opening of 800 mm in such a condenser? Also, what is an appropriate steam flow rate in the pipe from the top of the vacuum distillation column to the condenser? Which book has information on this topic? ! Everyone is most welcome to come and discuss
Wasn’t the pipe diameter already determined? These data are in the \"Chemical Process Design Manual\".
For condensers designed under vacuum conditions, the steam flow rate is selected within the range of 8~30 m/s. 20 m/s is generally chosen. It should also be noted that when calculating the pipe diameter, it must be done based on standard conditions, regardless of whether the system is under vacuum or not.
Which method did the original poster ultimately choose?
A diameter of 1400 with an opening of 800 is feasible; however, for reinforcement of the opening, equal-area reinforcement cannot be used – instead, the pressure area method must be employed
Reply to 5# hy_chenbi: Can holes be made? Have you tried it using your method? Which company is using such equipment nowadays?
