What's going on with the raging fire in the blast furnace of a petrochemical company? !

What's going on with the raging fires in petrochemical companies? ! I often pass by several large petrochemical companies. A few kilometers away, I can see fire dragons on several high towers. The first time it was strange, the second time I thought maybe it hadn't been repaired yet, and the third time I couldn't understand it. The Olympic torch only lasts for a few dozen days and will eventually be extinguished. Is the torch of the petrochemical enterprise a symbol of a raging fire that will never be extinguished? 1. How much does a fire dragon burn in a day? How much does it cost in a year? How much will the country burn? 2. How serious the pollution is. The workers may take shuttle buses back to the city to rest, but the surrounding people may have to live in such an environment every day. Besides, workers also have to work in such an environment! I have no other ideas. I hope everyone will pay attention and find a solution. 1. Is there no way to recycle it, at least the fuel? Maybe still very good ingredients. 2. It should be good for the environment.
It’s not that you don’t want to recycle, maybe it’s because the current technology and process conditions are not up to par, right?
That's called a torch in refining and chemical companies, and it's indispensable. The main component is catalytic dry gas (non-condensable gas). To utilize the dry gas from the torch requires a large investment and requires a user unit. Refining and chemical companies generally use it themselves to make fuel gas. What is no longer used is burned.
Hehe, no one will give you the answer!
That is the torch of the petrochemical enterprise. The torch is a safety measure to ensure the normal production of the petrochemical enterprise's equipment. Once a certain equipment or operating system of the device fails, the pressure needs to be released urgently, so that the discharged gas will enter the vent oil and gas pipeline network and then enter the flare for combustion. Theoretically, each device operates smoothly and there should be no flare gas combustion. However, in order to ensure that the fuel gas discharged into the torch in an emergency can be burned in time, the torch is generally equipped with a permanent light. Only keep the lights on during normal production. At present, in order to reduce the direct input of flare gas into the flare for combustion, major petrochemical companies have set up flare gas recovery systems to achieve energy conservation and emission reduction. Now if a raging fire is found, it means that there is an accident in the factory. During normal production, there is only a small torch, that is, a permanent light.
Unused furnace exhaust gas must be burned and emitted, otherwise it will cause an explosion if emitted into the atmosphere, which is unsafe.
Light the sky lanterns. Recycling may be more expensive and simply burn it.
Sometimes it is possible to use some combustible gas to generate steam to generate electricity. It's just that petrochemical companies don't care about this saving at all.
personal opinion: 1 For individuals, the amounts of these gases are indeed large, but for petrochemical companies, they are very small. 2 These gases are difficult to utilize: As mentioned on the 5th floor, the daily amount is not fixed. 3 There are technical difficulties.
The emissions may be carbon monoxide and sulfur oxides, and burning them above is secondary combustion to prevent acid rain and deflagration. What do you think? * * Energy is so important. What we need to burn is money. What we need is environmental protection and ecology.
The main component of emissions is gas. Some good companies recover part of it from waste heat boilers and heating furnaces, but the technology is difficult and the operating costs are high. Therefore, most companies choose to burn it at high altitudes, which is definitely a waste of energy. Our company is trying to solve this problem and strive to minimize losses.
If you think you can still use it, just use it! As long as you don’t lose money!
Petrochemical flares are CO and hydrocarbon gases emitted in the process system. Its principle is the same as the purge gas of the methanol system, ensuring automatic evacuation of the process pressure. In order to prevent this part of the gas from polluting the atmosphere, companies use torches to incinerate this part of the waste gas. It is difficult to use this part of the waste gas, and the recycling cost is very high.
Some residual gases cannot be utilized and are directly emitted and pollute the environment, so they are burned directly.
