Well Ted, I can suggest what I would do, is to take the info I see on Google images, which I just looked at myself, HO scale oil refinery kits, search and learn just how a refinery works, from raw to finished product, and plan my own arrangement, to fit the space I had to work with. Walthers offers a lot of parts, and pieces, and I think Kibri also had a kit.
I also used sprues to model piping. But different kits are availiable with valves, and such, molded in.
Have fun designing to fit your space and needs !

I am planning building an oil refinery, since I have ordered 10 of the Atlas 31000 gallon tank cars for my layout. I have been looking at Google Images and googled how refineries work. But I have to admit looking at how refineries are a maze of pipes and tanks, it seems a bit intimidating to attempt such a thing from scratch. I have been saving the sprues from many model kits and plastic caps from various household products. Are there any ideas or plans out there that could be roughly followed? I have track space for the 10 tankcars and about one foot by two foot space for the refinery. Any help, guidance, links, would be appreciated. Thank you.
Ted
