Problems with the setting of safety valves in distillation towers
Thread Content
Our facility has six sets of pressure-driven distillation units, with an operating pressure of around 0.3 MPa. However, no safety valves have been installed at the top of the condensers; only self-regulating valves for discharging exhaust gases are present. According to relevant standards, such self-regulating valves cannot be considered safety devices, and they cannot ensure safety in the event of a failure. The design agency stated that the material in question is sensitive to temperature, so the pressure drops rapidly once heating is stopped, and therefore there is no need for safety valves. Is there any basis for this claim?
I think it should be designed so that, in the event of a failure in the cooling system
It should be set in accordance with the specifications; if the design institute provides such an answer, then it should present the relevant explanations from the specifications. Although in practice, a safety valve might not actually be necessary
Safety valves must be installed to ensure the safety of tower equipment. Moreover, how can safety valves be used regularly? Low pressure or infrequent use are not reasons for not installing them.
Yes, safety issues must be taken seriously! Safety valves must be installed.
I don’t think it’s necessary to design a safety valve, as your material is sensitive to temperature and no higher pressure will be generated once it reaches the condenser!
Is there any basis for the answer on the 6th floor?
Safety valves must be designed; in the event of problems with the condensation system, they serve as the last line of defense.
In any case, a safety valve should be installed; if regulations require it, then it must be done in accordance with those regulations
According to the regulations, safety valves must be designed, as anything can happen in an emergency situation.
A tower definitely needs to be equipped with safety valves, for the safety of the equipment. Unless the top of the tower is directly connected to another device that already has safety valves, these valves are essential in pressure-driven distillation towers, as overpressure can occur quite easily. This is especially true at the beginning of operation, when it’s difficult to control the tower pressure. I’ve encountered this situation before: in a tower with a pressure of 0.4 MPa, it was necessary to use the safety valve bypass to relieve pressure during boiling processes, haha. :L
