Can butadiene and vinyl chloride be released directly into the atmosphere?
Thread Content
As the title suggests, diene and vinyl chloride do not have flare systems – is it acceptable to release them directly into the atmosphere? Are there any guidelines?
Section 5.5 of the Petrochemical Regulations discusses emission issues, which can be referred to
Health hazards of butadiene: This substance has **irritating effects. Acute poisoning: In mild cases, symptoms include headache, dizziness, nausea, sore throat, tinnitus, general fatigue, and drowsiness. In severe cases, symptoms such as a drunken state, difficulty breathing, and a rapid pulse occur, followed by loss of consciousness and convulsions; sometimes mental symptoms such as restlessness and wandering around are also present. Recover quickly after disengagement. Headaches and drowsiness can sometimes last for some time. Direct skin contact with butadiene can cause burns or frostbite. Chronic effects: Prolonged exposure to certain concentrations of butadiene can cause symptoms such as headache, dizziness, general fatigue, insomnia, frequent dreams, memory loss, nausea, and palpitations. Eczema and polyneuritis are occasionally seen. Environmental hazards: It is harmful to the environment and can pollute water bodies, soil, and the atmosphere. Fire and explosion hazard: This product is flammable and irritating. Vinyl chloride: Prolonged exposure can cause vinyl chloride disease. Acute poisoning: In cases of mild poisoning, patients experience dizziness, chest tightness, drowsiness, and unsteady gait ； Severe poisoning can lead to coma, convulsions, and even death. Skin contact with vinyl chloride liquid can cause erythema, edema, or necrosis. Chronic poisoning: It is manifested as neurasthenic syndrome, hepatomegaly, abnormal liver function, digestive dysfunction, Raynaud’s phenomenon, and acroosteolysis. The skin may experience dryness, cracking, scaling, eczema, etc. Other harmful effects: Vinyl chloride can participate in photochemical smog reactions in the environment. Due to its high volatility, it is easily photolyzed in the atmosphere; it can also be biodegraded and chemically degraded – that is, it can be broken down by specific microbial communities, or it can be oxidized by oxygen in the air to form anisole, formaldehyde, and small amounts of phenylethanol. As can be seen from the above, these two substances cannot be discharged directly ；

It is also necessary to consider whether the company has strong connections with the local environmental protection agency and local authorities Additionally, it is necessary to see whether the reaction from the local residents after the emissions is intense Furthermore, butadiene and vinyl chloride are highly toxic; yet this company dares to discharge them directly into the environment. Where is its conscience, where is its professional ethics?
We have butadiene here; neither the safety valves nor the burst disks discharge directly into the atmosphere, but rather into the incinerator.
Butadiene to flare. Vinyl chloride needs to be treated in an environmentally friendly manner
