Abstract

Black liquor gasification systems offer the potential to replace black liquor recovery boilers because of their increased energy efficiency, reduced emission of pollutants, and inherently safer designs. However, there are significant problems that must be addressed, not the least of which is the selection of suitable materials for containment of the processes associated with gasification. There are two gasification systems that are considerably ahead of all others in terms of development efforts and commercialization. One of these systems operates at a temperature sufficiently high that the inorganic salts are present in the molten state. A description of this system and the operating environments are presented, along with a summary of the performance of materials in this system. Initial laboratory studies in simulated gasifier environments indicate that there are significant materials issues to be resolved.
