Optimization of Crude Palm Oil Recovery Using a Single-Stage Cartridge Coalescer System

Abstract

This study evaluates the limitations of the current two-stage Rapid Tank Crude Palm Oil (CPO) recovery process and proposes a next-generation, single-stage system utilizing cartridge coalescer technology. The primary objective is to minimize oil losses in the underflow, enhance separation efficiency, and develop a more scalable and modular solution tailored for palm oil mill operations. While the existing Rapid Process Flow employed by Sime Darby achieves relatively high CPO recovery, it still suffers from inefficiencies—most notably, significant oil losses in the aqueous underflow, especially under fluctuating feed conditions. Additionally, reliance on multi-stage equipment increases system complexity and capital expenditure. The current setup is not optimized for variable feed characteristics, such as changes in oil concentration or emulsification levels. Furthermore, the absence of a standardized replication framework limits scalability and adaptability. This study introduces an alternative solution designed to address these challenges through a simplified, data-driven, and modular approach.
