Grangemouth oil refinary just caught my attention on the news, now here comes some probably daft questions but im curious to know.

Now, in the background there was the refinary.. But, there was a towers with a flame coming out the top:

1) What is that for?
2) How dosnt it explode?

Slightly weird.

There's a few of them on the refinery on Canvey too, they burn constantly. I assume it's just an exhaust of sorts for some part or other of the refining process.

the chimney is a flare stack, designed for burning off excess gas from overfilled tanks etc. (doing a health and safety on one of these as part of my degeree at moment - oh the fun)

Depending on the facility, they can have a permantantly lit flare tower, so that in an emergency they can "blowdown" the gas inventory to atmosphere without ending up with tons of toxic and explosive gas floating about the place.
