What is the current use of the Unibon in refineries?

The Unibon process is specifically designed for the removal of sulfur compounds from feedstocks, especially when preparing streams for the Fluid Catalytic Cracking Unit (FCCU). Sulfur is a contaminant that can poison catalysts, affect the quality of final products, and lead to regulatory and environmental issues due to emissions of sulfur oxides during combustion. By effectively reducing sulfur content, the Unibon process enhances the overall efficiency and performance of the FCCU, allowing for the production of cleaner fuels.

In contrast, the other options relate to processes or functions that are not the primary focus of Unibon. For example, while processes exist to remove benzene or improve octane ratings, these do not reflect the main purpose of Unibon’s sulfur removal capability. Essentially, the Unibon technology contributes significantly to refining operations by ensuring compliance with environmental standards and improving catalyst longevity through effective sulfur management.
