From their website:
Dakota Oil Processing, LLC is a privately held, development stage company formed for the purpose of developing, constructing, owning and operating a crude oil topping refinery near Trenton, North Dakota.I don't know the exact location of the proposed refinery but it will no doubt be located very near the Trenton crude-by-rail oil-loading facility. That's coming along very nicely. It appears track has been laid. It will be interesting to see the actual facility.
DOP intends to construct a 20,000 barrel-per-day crude oil diesel hydro-skimming refinery near Trenton, North Dakota. The Project will receive and process light sweet crude and sell No. 1 and No. 2 ultra low sulfur diesel (ULSD) refined as the primary products for the local and regional markets. The secondary products produced will be naphtha, residual fuel oil and elemental sulfur, which will be sold as commodities into various markets. Propane will be refined and separated and either sold or used as plant gas.
As far as I know, the refinery project remains on track. [I went back to proofread this. No pun in intended in that last sentence.]
