| Abstract: | Increasing demand is fueling the booming polyurethane industry worldwide. An impeding issue for polyurethane industry is how to handle the large quantity of hydrogen chloride byproduct generated from the synthesis of intermediates, i.e., isocyanates. In the meantime, the traditional chloro-alkaline process suffers both from the high energy intensity of electrolysis method and the disparity in the chlorine and caustic soda market. To solve these problems, the state-of-the-art chlorine recycling technologies ... |
