Hydrogen production economic assumptions

In an effort to provide a common base for the economics of this symposium, a common list of cost assumptions was used as the basis for most of the chapters. (This list is included as the Appendix.) This volume presents this informative symposium to the larger audience who wishes to keep current on the technology, economics, and production relating to hydrogen. 

Several attempts have been made to evaluate and compare hydrogen sulfide scavenging processes based on economic analyses. Unfortunately, such studies are of limited value because they are highly dependent on the specific conditions and assumptions used in the study. Also, other factors, such as the environmental acceptability of the reactant and its waste products, operator acceptance of the process, and winterizing requirements, may be more important than cost in selecting a process. The very high rate of process modification, new process development, and removal of existing processes from the market also makes comparative evaluation difficult in this field.
