Tunable co2-mediated electro-selective process for oil bleaching
Electro-selective oil bleaching technology that uses tunable CO2 and electric fields to selectively remove polar pigments, oxidation products, and trace metals. By shifting from passive adsorption to controlled CO2-mediated electrochemistry, it aims to reduce reliance on bleaching minerals, lower energy use, minimize waste, and improve oil yield while providing enhanced operational control and compatibility with existing refinery workflows.
Overview
The Tunable CO2-Mediated Electro-Selective Process for Oil Bleaching is an approach to edible oil refining that replaces traditional passive adsorption with a more efficient, selective purification method using controlled electric fields and CO2-mediated chemistry. The process enables selective mobilization and removal of polar pigments, oxidation products, and trace metals from edible oils, with the goal of reducing the need for bleaching minerals. Expected benefits include improved oil yield, reduced energy consumption, minimal waste, and enhanced operational control, designed to fit into existing refinery infrastructure.
