This document outlines the process and equipment for producing pure ester. It involves pumping chemicals like sulfat, CPO, methanol, and NaOH into an esterification reactor where they are heated and stirred to produce ester and glycerol. The ester and glycerol are then pumped into a transesterification reactor for further heating, stirring, and processing to separate pure ester. The pure ester is distilled in a distillation unit while the other components are removed.
