Economics of synfuel and gasification systems
The performance characteristics of several gasification systems are discussed. Cost estimates of various synthetic fuels are presented. The lowest cost synthetic fuel is significantly above the current natural gas price of about $2.75/MMBtu and about equivalent to present oil prices at the plant gate. Gas prices for the Welman-Galusha gasifier would have to be increased significantly if the plant ran on two shifts only or if the gasifiers were not fully loaded. For industrial application the lowest cost fuel is probably the direct use of low sulfur coal with some post combustion pollution control. This is followed by the atmospheric fluidized bed combustor. Coal/oil mixtures and solvent refined coal liquids (SRC I or SRC II) are the next options. High Btu gas from a large coal gasification plant will be more competitive for industrial use. Large industrial uses in the range of 1000 tons of coal a day may find reduced costs with an entrained coal conversion unit such as a Texaco or the Saarberg-Otto Gasifiers. However, before 1985 when the gas price decontrol has been felt, it is unlikely that low Btu gas, medium Btu gas and methanol will be an economical choice for industrial users.
