In a kraft recovery dissolving tank, high temperature molten smelt droplets fall into an aqueous solution and dissolve. The rapid heat transfer between molten smelt and water can lead to violent dissolving tank operation, and in severe cases, a dissolving tank explosion. In this study, an experimental apparatus was built to investigate the interaction between a molten synthetic smelt droplet and water. Smelt-water interaction was documented, and the effects of water and smelt temperatures on droplet explosion probability, explosion delay time, and explosion intensity were examined. The results show that explosions always occur below a lower critical water temperature, which is a function of smelt temperature, and never explodes above an upper critical water temperature. Up to the upper critical water temperature, as the water temperature increases, the explosion probability decreases, and the explosion delay time and the explosion intensity increases. A Smelt-Water Interaction Temperature (SWIT) diagram was constructed to describe the explosion probability at different smelt and water temperatures.

Sultan Technikon, 2002. / The extent of diffusion and surface modification of a purified 23.6 kDa xylanase isolated from Thermomyces lanuginosus on bagasse pulp was evaluated. Polyclonal anti-xylanase antibodies were raised in two rabbits and in conjunction with immunogold labeling and microscopic studies enzyme diffusion and degradation studies were performed. The purity of the xylanase was confirmed by SDS-PAGE and western blots confirmed the antigen-antibody hybrid on the nitrocellulose membrane. / D
