Do high-risk processes in atmospheric-pressure reactions require safety valves?
Thread Content
For high-risk processes involving reactions at atmospheric pressure, with exhaust gases being discharged through pipelines connected to exhaust treatment devices, is it still necessary to install safety valves or other relief measures?
Is the exhaust treatment device turned off? If not, it can be omitted (provided the size of the exhaust pipe is sufficient)
The exhaust system is kept running continuously without being turned off; however, safety valves are required by the regulations for high-risk processes, which seems unreasonable to me
Specifications are general requirements; there must always be a premise, such as something like \"in case of overpressure risk\", etc. If you analyze and find that this condition does not apply, then such specifications are not necessary
In my humble opinion, even if the exhaust gas treatment system does not have a shut-off valve, a safety valve should still be installed. For example, in the event of a sudden power outage or if the control valves for the reactor or the cooling water system lose control, it is very likely that the reactor will experience overpressure; without such a safety device, it’s like having a time bomb!
Does this term \"high-risk processes\" refer to hazardous chemical processes that are under strict supervision? If so, not a single one of the above measures may be omitted. If not, or when considering it purely theoretically, it is a matter of discharge volume. Whether it’s a safety valve, a burst disc, or even something that’s simply left open as you mentioned, the key issue is that it must be able to allow for emergency release in the event of excessive temperature or pressure. This is just my personal opinion; please feel free to give your feedback
Since it is a hazardous process, overheating and overpressure under abnormal conditions are bound to occur. Safety valves and shut-off valves are essential.
Since it is a high-risk process, safety devices such as safety valves or explosion-proof membranes should be installed. There are no such things as accidents in chemical production. Safety first.
It is necessary; even if it isn’t required under normal operating conditions, we still need to consider safety issues in abnormal situations. If there is a risk of overpressure under such conditions, then it must be installed
