What equipment should be used to reduce the pressure of reaction gases?
Thread Content
Dear friends, if you want to reduce the pressure of the reaction gas after it is released for further processing, what equipment should you use? What kind of power is this equipment driven by, and what graphic representation should be used in the PID diagram? Thank you very much!
Just add a pressure reducing valve, which can be represented by a self-standing regulating valve on the PID.
Well, after studying our process, I feel that using an expander is more appropriate. But there is still a question, do the expander and compressor have the same icon on the PID?
You can install an automatic diaphragm regulating valve to adjust to the required pressure. If the pressure is higher than this, it can be drained.
Reply 4# tiedani This kind of thing is just a representative, it doesn’t have to be unified, it just needs to be able to explain the problem! Different design institutes have different drawing methods, so what if you just draw it like a centrifugal pump? The details can be determined based on the shape of the final selected equipment.
Reply 6# zloty_zh Thank you for your answer, but we are just competing now and require some regulations.
Reply 4# tiedani example: All are trapezoidal structures, with the press having a large inlet and a small outlet, and the expander having a small inlet and a large outlet. Do you know about steam turbines? To make an inappropriate analogy, consider the steam turbine as an expander, and the steam inlet and outlet of the turbine are in turn the compressor.
