From what I can see, the basin you marked with red is the drain sump of the unit. At the end of the coking process, the coke is quenched with water which needs to be contained somewhere since it is heavily contaminated. Its position next to the six coke drums right in the middle of the unit also suggest that. The drain sump doesn't need a roof at all in my opinion. The tall structure right above the coke drums is the main fractionator column alongside its two smaller sidecut stripper columns. The two narrow towers to the right are just chimneys for excess steam and the smoke from the furnace, the one right next to it actually being the chimney for the furnace which sits right beneath it. I can't really tell what the thing in blue is supposed to be, but my educated guess would be that it is some sort of pump house. You can safely assume that everything contained within these streets belongs to the coker unit. I really hope this was helpful!

Hey, first of all, I'm more than astounded by this mod an the effort put into it. It's absolutely wonderful and looks great! I would also like to offer my advice on any issues or questions that might occur since I'm a M.Eng. in Chemical Engineering and currently employed in the Projects & Planning Department of a large chemical manufacturing Company. It would be great if this mod was as close to reality as possible and I would love to contribute to that! Keep up the great work!
