Crown develops new advanced catalyst reduction and economization process

December 18, 2018 |

In Minnesota, Crown announced a new processor upgrade for biodiesel manufacturers: advanced catalyst reduction and economization (ACRE). ACRE allows biodiesel processing plants to run at the lowest operating cost and highest efficiency by adding a third transesterification reaction step while also delivering an energy-efficient design for reduced cooling load and steam use. The ACRE processing innovation is already running successfully in multiple plants and yielding impressive results in multiple geographies, and with multiple feedstocks. Plants in production are achieving 40-plus percent catalyst reduction and experiencing savings of 3 cents per gallon. In addition, ACRE is designed to reduce acid usages, promote energy savings through economization and increase manufacturing uptime.
