If you look at the picture in detail I think you will see that this is a view of an unfinished work in progress.

Item:
The platforming - it looks "New", it looks clean having no indication of spillage or aging.

The large center pipe/equipment/whatever - It stops at the flange below the reducer and does not continue through the banded hole in the platform below. Something is missing.

The area in general - There is loose trash and cable on the platform that indicates "still under construction" status. This is further born out by the presents of erected scaffolding in the background.

What's missing - If this is really in a "Refining" (Refinery) situation then I would expect to see insulated equipment and piping. So far there is no insulation on this equipment/piping. Does this mean that this picture is not of a "Hot" system or does this support the idea that it is an unfinished construction site?
