Planning for Coal Gasification

The decline in deliverability of conventional natural gas supplies and the general energy crisis have resulted in national programs directed toward the commercialization of energy conversion technologies. Foremost among these efforts is the gasification of coal. Coal reserves represent our most abundant fossil fuel resource. Its utilization is hampered both by its form value and its pollution qualities. Coal gasification is commercially feasible today and projects requiring hundreds of millions of dollars and years of construction time are underway. This paper provides a perspective for the scope, time, and cost of these venture projects. Resource requirements, plant products, and coal gasification processes are discussed. Emphasis is placed on the effects of coal feedstock and prices on plant economics.
