Western Research Institute (WRI) has developed a process titled TaBoRR{trademark} (Tank Bottom Recovery and Remediation) that remediates tank bottom wastes and recovers refinery acceptable crude oil. This work provides: support for the field demonstration unit; equipment, materials, and labor for construction and operation of a laboratory unit; and numerical and economic modeling of the process. This report includes an interim update on Task 1.4 entitled {open_quotes}Tank Bottom Waste Processing using the TaBoRR{trademark} Process,{close_quotes} which includes the results of the work to date. The objective of this work is to develop information for the successful deployment of WRI`s patented TaBoRR technology. This objective is being accomplished by providing: technology support to the field demonstration unit, the design and operation of a laboratory process unit, and numerical and economic analysis. The results of the work performed under this task are reported. Presently, the level of effort in support of the field demonstration unit has been limited to analysis of two sources of tank bottom wastes. The results of these analyses indicate that the samples contain solid concentrations from 1 to 9 wt % and water concentrations between 10 and 53 wt %. Certain analytical separation techniques should be avoided in the separation of components contained in tank bottom wastes. Also reported are the true boiling point curves for the crude oil present in the tank bottom wastes. The design of the laboratory unit is complete and is reported. Component sizes obtained during the design effort have been confirmed by a numerical simulator. Currently, the construction of the laboratory unit is approximately 95% complete. Shakedown tests and experimental procedures will be performed and developed after construction is complete. Economic and process modeling will be performed after the completion of experiments with tank bottom wastes.
