Automated System in Clarification Process on OER Improvement

(Officer Incharge: Fatah Yah Abd. Manaf)

Currently, there are no reliable methods of maintaining the oil to crude oil ratio and in actual practice most mills do not alter dilution control with widely fluctuating mill throughputs. Crude palm oil (CPO) that is discharged from the presses is highly viscous. Thus separation of the oil from the solid and water is difficult without the addition of dilution water. In practice it has been found that 38 to 40% of the crude oil will be the best for clean separation in the settling tank (Mongana Report). Over dilution will result in poor settling rate and large amount of water is required in the process. The automatic CPO dilution control was successful in controlling to maintain oil in CPO at 39% to 41%

Objective

• to maintain a constant dilution rate for  diluted crude  oil in the clarifier process

• to provide better process control on  product losses.
