Biodiesel Design/Start-Up

Project Description

Sacré-Davey used their experience with solid metal catalysts in renewable fuels to design a pretreatment process for a broader range of feedstocks (40% FFA max) to suit Benefuel’s high-temperature and high-pressure catalytic technology. Additional variations of the standard pretreatment methods: degumming (water and enzymatic) and bleaching (batch atmospheric, batch vacuum, and continuous vacuum), were evaluated. The final pretreatment process included a creative solution that included a continuous vacuum drying system to meet moisture requirements and a guard column as an additional purification step for assurance in meeting feedstock specifications.
