                  It has been estimated that the investment of a plant designed to produce 100 million ft.³ per day of high-B.t.u. pipeline gas is approximately %52.5 million.  The cost of larger plants will be proportional to their size.  The cost of producing the gas has been shown to be $0.55 per 1,000 std. ft.³ when the charging stock is a noncaking coal or char having a heating value of 26 million B.t.u. per ton and containing no tar-forming materials, available at $4.00 per ton.  This study has shown that the cost of CH₄ from coal is closely related to the cost of coal.  With fuel costing $4.00 per ton, fuel represents 45% of the cost of gas, at $8.00 per ton it is 60%.  The overall thermal efficiency of this process compares favorably with other processes for converting coal into more readily available forms of energy. It has also shown that >90% of the cost of producing high-B.t.u. pipeline gas lies in the production of the purified synthesis gas.  Therefore, efforts to reduce the cost must be directed toward reducing the cost of the synthesis gas.  Proper selection and pretreatment of the coal to allow its introduction into the gas generator without prior removal of its tar and oil content will effectively reduce its cost, resulting in lowered gas cost.
