Carbon dioxide deliming in leather production: a literature review

In this article, carbon dioxide deliming development in leather process was comprehensively reviewed. Based on carbon dioxide properties and its solubility in water, carbon dioxide deliming principle and mass transfer were analyzed, respectively. It was creative to propose reuse of carbon dioxide with available absorption and desorption technology which reduces occupational safety risk, regenerates new resource and leads to a cleaner production. Additionally this review provided the possible ways forwards of this technology. This review aims to give an overview of fundamentals, process optimization, occupational safety and possible ways forwards of carbon dioxide deliming in leather, and to provide useful information to researchers and engineers in this field.
