Abstract

Cabot Corporation, a global leader in the specialty chemical and performance material industry, has been developing ink dispersions for inkjet printers for the packaging industry. The goal of this project was to explore methods for optimizing the filtration process of Cabot’s yellow dispersion focused on the impact of changes to their operational procedure and an analysis of new filtration technologies. We found that changes in operational procedures such as recirculation and increased flow rate did not improve the efficiency of pre-filtration within the process; however, the introduction of new filter technology had a more sufficient impact. Our results demonstrate the benefit of using filter aids in a double pass method to obtain satisfactory throughput and filtration standards.
