Why didn't the fire on the offshore oil platform go out and keep burning?

No matter whether it is land or offshore oil exploitation, there are associated gases (a classification of natural gas) in oil, which are basically combustible substances such as methane and ethane, and of course other elements such as sulfur and nitrogen. Due to the high underground pressure during mining, this associated gas will be discharged from the well. If it is left to be sprayed into the air, it will pollute the atmosphere and cause personnel poisoning. The best way is to recycle and purify it into usable gas (that is, natural gas as we usually say), but the drilling platform is far from the land and cannot be collected, so we have to burn it, and after burning it, it will become non-toxic CO2 and other gases, which can be discharged into the atmosphere. This is also a helpless move. Many years ago, the technology failed, and the ever-burning lamp of the refinery (that is, the torch of the refinery) burned all the year round, which is also the reason. Now that there is a way to recycle it, it will not be burned. I hope I answered your question.
