Washing Systems for Biodiesel Purification
The washing stage in biodiesel refining begins after decantation of the transesterification reaction, aiming at the rigorous purification of the final product. Through the acidified water washing method, critical contaminants such as free glycerin, soaps, salt residues, excess alcohol, and catalyst are removed. Clark Solutions’ systems use columns equipped with high-performance random packing, which increase the contact area and interaction time between the liquid phases. This advanced engineering ensures proper dispersion, prevents droplet shearing, and enables efficient mass transfer, resulting in a high-purity product with full technical compliance.
Liquid-Liquid Extraction and Efficiency with Random Packing
Overall Efficiency
Minimization of residual losses and increased productivity in the refining process.
Reduced Water Consumption
Greater contact area enabling impurity removal with lower water volume.
Regulatory Compliance
Precise sizing to meet acceptable impurity content standards.
Operational Flexibility
Systems adaptable to different operating ranges and flow conditions.
Product Integrity
Prevention of coalescence and controlled dispersion to ensure high purity.
