This paper discusses the results of development work on the control of crude oil dilution in palm oil mills. The importance of crude oil dilution in palm oil mills is clearly shown by a simple cost-benefit analysis. Preliminary results from a three-phase decanter trial have shown that, besides a clarification system using horizontal or vertical clarifiers, dilution control is also important to a decanter system.A practical approach to the automatic control of crude oil dilution using a flow ratio control system is discussed in depth in this paper. Results obtained from the evaluation of Doppler and magnetic flowmeters have shown that the major obstacle in automatic control of crude oil dilution, i.e., the selection of a suitable flowmeter to measure crude oil flow, has been overcome.
