Oil and profit boost calculator

Palm oil extraction is a complex process that consists of several steps, which we discuss in detail in our article. At each stage, it’s crucial to monitor metrics that can increase oil extraction rate (OER), minimize oil loss and reduce emulsion in the underflow.

The calculator is only a technical tool on our website that helps to estimate how much additional oil you can get after applying our reagent.
We’ve used the average data based on our experience of implementing reagents in palm oil mills. Let’s take a closer look at each metric.

 

• Capacity FFB, TPH

FFB are fresh fruit branches from which palm oil is mechanically extracted. In most mills, the amount of FFB is calculated by weight. This metric is used only for reference to compare with calculated Average FFB, TPH. It helps to align projected capacity with the real one.

• Average FFB, tn/day

The tonnes of FFB that the mill processes per day, as well as the Average OER, are needed to calculate the average crude palm oil volume (CPO, t/day).

• Current Average OER, %

Oil Extraction Rate (OER) is an indicator that shows the absolute percentage of oil the mill extracts from FFB on average per year. The higher the OER, the more oil a mill produces from FFB and the higher its efficiency.

OER is calculated by the formula:
OER = CPO/FFB⋅100%,
where CPO is the amount of palm oil produced by the mill in a year, FFB is the amount of palm fruit processed by the mill in a year.
The OER for most mills in Indonesia is in the range of 20–23%, for Malaysia it’s the range of 19–22%. This figure depends on the quality of FFB, condition of processing equipment and other factors.
An OER above 23% is considered good, indicating efficient processing of FFB by the mill.

• Oil content in COT (CST input)

Oil content in COT is the oil content in the Crude Oil Tank in volume percent.
Crude Oil Tank — the tank from which palm oil is delivered to the Continuous Settlig Tank (CST) for extraction.
Oil content in COT is measured in the laboratory by centrifugation. This indicator is checked once every 2–3 hours and is usually in the range of 30–40%. This indicator shows how much virgin oil has been diluted with water. It is used to calculate the reagent dosage.

Biopolymer technologies reagent helps to reduce the dilution of virgin oil with water and to increase the oil content in the COT up to 40% without increasing losses in the clarification stage. As a result, water consumption can be reduced by 50%.

• Working hours per day, h

This is the average number of hours per day a mill requires to complete the palm oil extraction process. The number of working hours for most mills is 16–20. However, there are mills that operate 24/7 as well as smaller mills with a working day of 12 hours.
The working hours per day is used to calculate the average FFB, TPH.

• Working days a year, day

The metric takes into account the mill schedule and is used to calculate annual values. Typically, with a six-day working week, it takes about 310 working days per year.

• CPO price, USD/tn

The cost per tonne of Crude Palm Oil (CPO) in USD at which mill sells CPO.


 

• OER increase, p.p

The average increase in OER in percentage points that Biopolymer Technologies staff observed during the reagent application on the mills.

• Reagent dosing rate, g/l and its concentration, %

Dosage per sludge flow and concentration of the palm oil extraction reagent working solution. Optimal parameters determined by experience to maximise palm oil extraction efficiency.

• Reagent price, USD/kg

Recommended price per kilogram of reagent to achieve optimal Economic Value Added (EVA).

 


Most of the parameters are calculated based on the mill's performance per hour, day, month or year. They help to evaluate the productivity of the mill and to estimate the amount of additional oil that can be obtained after applying the reagent.

• CPO, tn/year

The metric shows the palm oil that the mill produces in a year without using the reagent.

• Additional CPO, tn/ year

This metric shows how many additional tonnes of CPO per year the mill will produce after applying the oil extraction agent.
The EVA is calculated from the resulting additional oil per year.

• Economic Value Added (EVA) with reagent dosing

This is the final estimation that shows how justified the implementation of the reagent is to improve the quality of palm oil extraction.
EVA is calculated by the formula:
EVA = ((Additional Oil cost – reagent cost))/(reagent cost)

• Profit, USD/year

The total additional profit in USD per year is the ultimate measure of the effectiveness of working with Biopolymer technologies reagent.


Biopolymer technologies reagent brings attractive EVA in two ways:

1. By increasing OER — extracting more oil from the same amount of FFB without extending retention time.
2. By boosting mill productivity — processing more FFB per hour by reducing retention time in the CST.
