Phase I: The Pipeline Gas Demonstration Plant: Coal Fines Briquetting Study
- Continental Oil Company, Stamford, CT (United States)
Normally fixed-bed gasifiers require a sized coal feed (ca. 2'' x 1/4''), and the run-of-mine coal must be crushed and screened to yield the requisite coal feed. This coal preparation step produces a coal fines (1/4'' x 0) by-product. A recent pilot plant test run has disclosed that the British Gas/Lurgi slagging gasifier can process Pittsburgh No. 8 coal containing a large percentage of coal fines without a reduction in throughput, and therefore a plant based on this process may not yield a coal fines by-product. This finding will be evaluated in more detail in the Phase III (Demonstration Plant Operations) of the project. In the interim, a preliminary design of a commercial plant has been completed based on the assumption that a sized coal feed is required for the process and that the coal fines by-product can be sold at a price equivalent to 90 percent of the cost of the run-of-mine coal. One promising alternative to selling the coal fines is to briquet them using a pitch or asphalt binder to produce a sized feedstock for the gasifier. This report evaluates this alernative. A preliminary design of a briquetting plant to handle 4,058 tons per day of coal fines has been completed. The briquetting plant is estimated to increase the erected plant cost for a commercial plant by about $7.5 million (0.8 percent). The cost of the resultant pipeline quality gas isincreased by about two percent in the most pessimistic case, and remains essentially unchanged in the most optimistic case.
