I had read the plant was for removing the sulphur, but maybe it does other stuff as well.
But why wouldn't the tanks explode if they were filled with gases? The shot I posted just shows holes poked in them. FALSE FLAG! They were empty!
All the black smoke was coming from some sort of tailing pond, here:

It is empty in the google photo, but was obviously full. Why target that? I can't imagine it was an accidental ignition considering the distance. Make it look worse? CONSPIRACY!
