    Abstract

    Steam reforming/gasification of the black liquor produced during wood pulping offers the potential for more efficient energy recovery, reduction of emissions and improved safety. This technology is currently being implemented in two North American semi-chem mills. As might be expected in scaling up any process system, a number of problems have been encountered. Degradation of metallic and refractory components has been observed in several areas, and this paper presents the results of the examinations of a number of these damaged metallic components. Carburization was observed in all cases indicating the environment was not as expected. Significant oxidation occurred, but the surface oxides formed appeared not to be protective. Studies currently in progress are directed toward identifying materials with resistance to the reformer/gasifier environments.
