- ASPHALT FROM TAR SANDS James<br />

STATUS OF OIL SANDS PROJECTS<br />

COMMERCIAL PROJECTS (Underline denotes changes since June 1994)<br />

W. Bunger and Associates, Inc. (T-5)<br />

J. W. Bunger and Associates, Inc. (JWBA) is developing a project for commercialization of Utah Tar Sands. The product of<br />

the venture will be asphalts and high value commodity products. The project contemplates a surface mine and water extraction<br />

of bitumen followed by clean-up and treatment of bitumen to manufacture specification asphaltic products. JWBA has secured<br />

rights to patented technology developed at the University of Utah for extraction and recovery of bitumen from mined ore.<br />

In 1990, JWBA completed a $550,000 R&D program for development of technology and assessment of markets, resources and<br />

economics for asphalt production. Later in 1990 JWBA initiated a program for value-added research to extract high value<br />

commodity and specialty products from tar sand bitumen. This program was initiated with an additional $50,000 in funding<br />

from DOE.<br />

Under this program funded by the U.S. DOE SBIR program, a 300 pound per hour PDU was designed and constructed. The<br />

unit has been operated to determine the effect of process variables and kinetic parameters. Recoveries of greater than<br />

97 percent have been experienced. The unit has been operated to produce gallon quantities of asphalt for testing and inspec<br />

tion. A field demonstration unit of 200 barrels per day has been designed and costed.<br />

Conceptual design and project economics for a 5.000 barrel/day commercial facility has been examined. Results show a strong<br />

potential for profitability at 1994 prices and costs.<br />

The commercialization plan calls for completion of research in 1995, construction and operation of a field demonstration plant<br />

by 1997 and commercial operations by 1999. The schedule is both technically realistic and financially feasible, says JWBA.<br />

Project Cost: Research and Development: $1.5 million<br />

Demonstration project: $10 million<br />

Commercial Facility: $135 million<br />

- BITUMOUNT PROJECT Solv-Ex Corp. (T-20)<br />

The Solv-Ex Bitumount Project will be a phased development of an open pit mine and an extraction plant using Solv-Ex's<br />

process for recovery of bitumen and metals.<br />

Solv-Ex will use a naphtha solvent to boost the power of hot water to separate oil from sand. The increased efficiency of the<br />

process increases oil yield and also allows metals such as gold, silver and titanium to be extracted from the very clean sand.<br />

Analyses of the pilot plant tailings (after bitumen extraction) showed that these minerals are readily recoverable.<br />

A Solv-Ex pilot plant, located in Albuquerque, New Mexico, can process up to 72 tons of oil sands per day. It can also produce<br />

up to 25 barrels of bitumen per day, depending on the grade of oil sands processed. The quantity of bitumen recoverable from<br />

tar sands depends on its bitumen content, which typically ranges from 4 to 12 percent.<br />

In an 8-month test program, Solv-Ex processed approximately 1,000 tons of Athabasca tar sands material in process runs of low<br />

(6 percent of bitumen), average (8 to 10 percent), and high (12 to 14 percent) grade oil sands through the pilot plant. The test<br />

material was procured from a pit centrally located in the oil sands deposit on which the Bitumount Lease is located. Average<br />

percentage of bitumen recovered for the low, average and high grade sands were 75, 90 and 95 percent, respectively.<br />

In February, 1989, a viable processing flowsheet was finalized which not only recovers the originally targeted gold, silver and<br />

titanium values but also the alumina values contained in the resource. Synthetic crude oil would represent about 25 percent of<br />

the potential mineral values recoverable from the Bitumount Lease.<br />

The results of this work indicate that the first module could be a single-train plant, much smaller than the 10,000 barrels per<br />

calendar day plant originally envisaged. The optimum size will be determined in the preconstruction feasibility study and this<br />

module is estimated to cost not more than C$200 million.<br />

The Bitumount lease covers 5,874 acres north of Fort McMurray, Alberta. Bitumen reserves on the lease are estimated at<br />

1.4 billion barrels.<br />

Solv-Ex is looking for potential financial partners to expand the project. The company plans to construct a modular Lease<br />

Evaluation Unit in Alberta at an estimated cost of $12 million.<br />
