Products and Services | Oil Retort
As the second part of its ambitious initiatives, Accel Energy plans to build a retort plant in China, where oil will be extracted from shale in a modern extraction facility. Retorting from shale oil has been used successfully in many countries as an auxiliary method of generating oil supplies. The success of developing resources from shale in Estonia encourages Accel Energy to operate its own retort technology in China and to begin with extraction. The Company will sell the resulting crude oil to local markets and use some of it to manufacture value-added products such as the Shale Asphalt Binder product which has higher profit margins than crude oil.
The proposed Accel Energy retort plant will become a source of crude oil, a well of sorts for the SAB. Below forty dollars a barrel, oil-shale oil is not competitive with conventional crude oil. However, with oil prices at $40 and higher and declining crude oil production in most areas, some investors are taking a look at the huge volume of potentially recoverable hydrocarbons in vast shale oil deposits. Accel Energy plans to extract 10,000 bpsd (barrels per stream day). The retorting process is noted for its simplicity, efficiency, and energy self-sufficiency. It employs gravity flow of shale in a moving bed through barrier-free; functional zones where the descending shale and countercurrent flow of air and recycle gas interact to provide both combustion heat for retorting and cooling for the retorted shale. The design for the commercial-size plant takes full advantage of the modular concept used in planning the 10,000-bpsd facility. It includes three full-scale module retorts, each with its own oil/gas-handling system. The design includes appropriate capacities in the mining, shalehandling, shale-disposal, fines-storage, and other auxiliary-facility areas. In addition to employing the basic retorting technology, the commercialplant design has numerous eminent features contributing to the project’s feasibility.
System attributes:

Retorting controlled by micro-processor computer-based system.
A design that permits use of relatively large shale (-3”, +3/8”) for retorting and discharges retorted shale in the same size range, facilitating disposal, stabilizing, and reclamation.
Minimal fugitive-dust problems.
Hydrotreating facilities to improve storage, transportation, and marketing qualities.
Use of product gas to generate electricity for both in-plant use and export purposes.
Comprehensive planning for site specifics, environment, health, safety, and socio-economics, in addition to the technical details for mining, retorting, product recovery, and storage/transportation.
Supplemental planning which includes alternatives to keep developments current and consistent with technical and economic needs as occasions demand.
