Abstract

Hydrogen synthesis gas, an important feedstock and energy component in the chemical and refining industries, is currently generated primarily from carbon fuels by one of the three well-known technologies: (1) steam reforming of light hydrocarbons, (2) partial oxidation of heavy hydrocarbons, (3) gasification of coal or other solid carbon compounds. Each of these three technologies has its own characteristics such as H 2:CO ratio without shifting; impurity levels of N 2, Ar, CH 4, H 2S, and COS; thermal efficiency; optimum operating pressure; and capital cost intensity. This paper compares the compositions and costs of these different hydrogen synthesis gas processes to provide a guide for the most economical utilization of carbon fuel resources. The major considerations in the economic selection are: relative feedstock cost over the life of the facility; the size of the facility; and co-production of products to achieve improved thermal efficiency and economy of scale.
