Wet-air oxidation of TS-1S wastewater
Tar sand wastewater has been treated using a bench-scale wet air oxidation process. The wastewater, designated TS-1S, was generated during in situ recovery of bitumen from Utah tar sand. After wet-air oxidation at 485/sup 0/F (252/sup 0/C) in the presence of air, the chemical oxygen demand (COD), total organic carbon (TOC), and total suspended solids (TSS) of the wastewater were reduced from 12,800, 3200, and 3860 mg/L to 285, 104, and 2 mg/L, respectively. Smaller reductions in COD, TOC, and TSS were achieved when the wastewater was wet oxidized at 422/sup 0/F (217/sup 0/C) and 466/sup 0/F (230/sup 0/C). The quantity of oxygen charged into the wet-air oxidation reactor was in excess of the amount required for oxidation and hence did not limit the rate of oxidation. The wet-air oxidation system recently developed at WRI was demonstrated to be effective in the destruction of organics at high temperatures and pressures. However, the equipment has limitations for kinetic studies of a low heating rate. A gas leak also occurred around the reactor packing seal. It is recommended that a complete thermal analysis of the reactor be made to identify modifications that will result in efficient heating of the reactor vessel. Improved temperature control will enhance the investigation of wastewater oxidation kinetics. 8 refs., 6 figs., 2 tabs.
