Impact of Dynamic Clarification on the extraction and recovery process of raw palm oil (case study)

The study evaluated the operation of a Tridecanter for 6 months and the results of quality and oil loss, consumption of industrial services, effluent volume and production indicators with historical records available for the plant from its start or compared to previous clarification management (static clarification). It was identified that the dilution required for the Tridecanter type equipment in the processing of press liquor is 1.8 oil / water, which represents a saving of 30% of water used in the present process compared to the 1.4 oil / water dilution oil used for static clarification. Likewise, it was found that the overall water consumption in the process went from 1.22 m³ / t CFF to 0.85 m³ / t CFF (fresh fruit bunch). The steam requirement is reduced by 14%, 595 to 511 kg steam / t CFF. Oil losses in the clarification phase decreased from 0.65% Ac/t CFF with static clarification to 0.45% Ac/t CFF with dynamic clarification. The effluent volume was reduced from 0.75 to 0.45 m3/t CFF. Likewise, the organic load decreased due to the removal of solids performed by the Tridecanter, which is reflected in the decrease in the COD (chemical oxygen demand) concentration, which went from 70,000 to 40,000 mg/l.
