Location of the safety valve in the pressure distillation tower: the materials inside the tower are corrosive
Thread Content
I have a question regarding a pressure distillation tower that is heated by direct steam; the substances inside the tower are corrosive. The operating conditions are 0.4 MPa and 150°C. Where should the safety valve be installed?
Pipelines are installed at the top of the tower, along with safety valves
What should be done if the tray gets clogged, with medium-pressure steam continuously being supplied to the tower bottom?
Search through literature to determine whether tray blockage occurs with such devices ? If so, considering setting up an alarm or interlock for the pressure difference at the top and bottom of the tower could help to shut off the steam and feed in a timely manner. For reference only.
It is possible to consider installing an anti-corrosion burst disc at the lower end of the safety valve
Considering the tower’s drag, the pressure is highest at the bottom of the tower.
