"This thesis deals with the design and cost analysis of four scaled up gasification plants. Reactor outputs range from 10 to 40 million Btu/hr (heating value of gas). Scale-up design parameters are based on data obtained from a 20 inch indirectly heated steam fluidized bed gasifier. This produces a medium Btu gas (450 Btu/ft3). The gas may be burnt on site or used as a chemical feedstock.
The plant designs consider reactor sizes, steam plant dimensions, specifications for feedhoppers, cyclones, conveying equipment, internal firetube heat exchangers, and drying plants.
The economic analysis deals with the cost of the above, and calculates the costs of producing 1 million Btu of the gas for each reactor size, thus allowing a comparison to be made with the current cost of natural gas, or gas produced by some other process.
Results of the analysis indicate a price of $23.12 per million Btu of gas for the 10x106 Btu/hr plant and $13.30/million Btu for the 40x106 Btu/hr plant, which are in excess of $6/million Btu which is the approximate cost of natural gas per million Btu.
These costs can be reduced by one third if feedflux values are increased from 140 to 185 lb/hr. Other factors may make the plants viable, such as close proximity of abundant supplies of waste wood"--Abstract, page iii.
