Where are the gases released by the safety valves, rupture discs, and pressure relief manholes in your chemical plant discharged to? Can it be released into the atmosphere?
What is the purpose of the special section on safety design for hazardous chemicals projects? Can this be decided by random talk?
Based on the design functional requirements, there are various emission pathways, such as flare systems and RTOs; release into the atmosphere is also an option.
It can’t be released directly into the atmosphere, right?
In short, it means moving to a safe place. Personally, I believe that the aforementioned pressure relief devices are meant to prevent overpressure in the equipment upstream of them; that is their purpose. As for safety areas, they are places that ensure the safety of people, property, and the environment. The extent to which something is considered safe is determined by the government, and it is influenced by many factors.
Phosgene and compressed air can’t be treated as the same thing, right? :Lol, usually in regulations, standards, and norms regarding the handling of toxic, harmful, flammable, and explosive materials, there is a requirement for \"proper handling\".
It is not a normal state of emission; there are various channels for emission. In emergency situations, safety comes first, and emission into the atmosphere cannot be ruled out.
It depends on the medium and the policies of the local environmental authority: handshake
In the chlor-alkali industry, the vent channel for the explosion-proof membrane of vinyl chloride spheres leads directly to the atmosphere. A couple of years ago, there were proposals to discharge it into vinyl chloride gas tanks; however, experts in the industry concluded that this would be even more dangerous than releasing it directly into the atmosphere. Vinyl chloride is considered a highly hazardous substance; are there any mandatory regulations regarding its release in emergency situations?
In the past one or two years, chlor-alkali enterprises have from time to time received \"Rectification Orders\" issued by experts organized by the local emergency management departments, stating that the safety valves of vinyl chloride storage tanks should discharge directly into the atmosphere!
The genius of an expert is that they only need to point out that what you’re doing is unsafe; they don’t need to tell you how to do it safely.
