Is it allowed for torches to emit large amounts of carbon dioxide?
Thread Content
The company’s carbon dioxide emissions from methanol washing are around 80,000 cubic meters per hour. We are considering switching to a flare system for emission; is this feasible? Please share your suggestions.
CO2 emissions should preferably be vented at a high level on-site, rather than through flare lines, to prevent corrosion caused by the dissolution of CO2.
It is recommended that the poster install a new CO2 recovery system to sell the byproduct, which might also generate some additional income. After all, long-term emissions of CO2 as a greenhouse gas is not a viable solution.
If flammable gases are released simultaneously, the flare will not be able to burn
Agree with the view from the 3rd floor. Also: Is carbon dioxide intended to be discharged through the flare system? Is your torch system idle? If so, then it’s possible! If it is in normal use, then it’s not allowed! Think about it: with such high levels of carbon dioxide emissions (around 80,000 cubic meters per hour), your torch system won’t be able to burn properly! ! !
Carbon dioxide should preferably not be discharged through the same pipeline as exhaust gases; it can be discharged separately at a higher point. It is best to handle and discharge it in accordance with environmental protection requirements.
It must be noted that flaring is not allowed for the following reasons: 1. Flares are used to discharge combustible gases, and they must be ignited during normal operation； 2. According to the data you provided, 80,000 units of gas are released per hour; the original flare tower is not capable of withstanding such pressure and is very likely to collapse ； 3. The introduction of inert gas CO2 prevents normal combustion of the flare. CO2 emissions are regulated by the Kyoto Protocol; it’s better to reduce emissions as much as possible. Our company refines and liquefies the excess CO2, which can be profitable. The investment in equipment is not high either; around 10 million yuan is sufficient.
One thing is certain: it cannot be emitted through the torches, mainly because the amount is too large
Thank you all. I found the latest version of the flare emission standards online, which clearly stipulate that emissions to flares are not allowed. Thank you again；
The volume was too large for the torch to handle; it was eventually discharged at high altitude after being processed in accordance with local environmental regulations
If there is a tall chimney, proceed with emission from the chimney.
