Oil Room in Palm Oil Mill
What is the “Oil Room” in a Palm Oil Mill?
In the field of palm oil processing, the “oil room” specifically refers to the crude oil clarification section (also known as the clarification workshop or oil pump room). It serves as a critical intermediate stage situated between the palm oil pressing section and the palm oil refining section. Its core function is to process the crude press liquor obtained from pressing palm fruit through sedimentation, separation, and clarification to produce pure Crude Palm Oil (CPO) and convey it to storage tanks.
Specifically, the oil room performs the following key tasks:
Solid-liquid separation: Removing solid impurities from the press liquor using equipment such as vibrating screens;
Heating and clarification: Heating the oil-water mixture to 85–90°C and utilizing density differences in clarification tanks to achieve three-phase separation of oil, water, and sludge;
Crude oil transfer: Pumping the clarified crude oil to storage tanks or directly to the refining workshop;
Oil filtration: Utilizing devices such as duplex filters and magnetic separators to capture mechanical impurities (e.g., metal fragments, plant fibers)—with filtration precision reaching 20–50 μm—thereby preventing downstream equipment clogs and oil contamination.
The oil room can be considered the “critical link” connecting pressing and refining; its operational efficiency directly impacts the production capacity of the entire palm oil processing line and the quality of the final oil product.
The Strategic Importance of the Oil Room in a Palm Oil Mill
The oil room holds an irreplaceable position within the complete palm oil production process. From the arrival of Fresh Fruit Bunches (FFB) to the dispatch of refined oil, the process encompasses: raw material reception → sterilization → threshing → oil pressing → crude oil clarification (Oil Room) → palm kernel recovery → refining → fractionation.
The oil palm is hailed as a “golden crop” and stands as the world’s most economically valuable oil-producing plant. As global demand for palm oil continues to rise and mills expand in scale and capacity, increasing importance is being placed on the design and equipment standards of the oil room. Studies indicate that adopting advanced filtration systems instead of traditional clarification processes in new palm oil mills can reduce the construction costs of the “oil room” by approximately 25%, with a payback period of just 3–4 years.
Furthermore, process control within the oil room directly impacts crude oil quality. Using unsuitable dilution media (such as sterilizer condensate or EFB liquor) during the clarification stage can increase the total chlorine and 3-MCPD content of the crude oil by about 30%, raise free fatty acid (FFA) levels by 7%, and increase the peroxide value by 25%, while reducing the DOBI (Deterioration of Bleachability Index) by 8%. Therefore, a well-designed and well-equipped oil room is crucial for ensuring palm oil food safety and enhancing economic returns.
Core Equipment of the Oil Room
A complete palm oil mill oil room typically comprises the following core equipment:
Vibrating Screen: Used to initially remove fibrous material and fruit residue solids from the pressed liquid;
Heating System: Heats the oil-water mixture to 85–90°C to reduce viscosity and facilitate separation;
Clarification Tank: Utilizes gravity sedimentation to achieve three-phase separation of oil, water, and sludge;
Recirculation Tank and Pump: Directs separated crude oil back into the clarification tank for secondary processing;
Chemical Centrifugal Pump: Pumps the conditioned oil-water mixture to the overhead tank;
Filtration System: Includes duplex filters and magnetic separators to ensure crude oil purity;
Oil Storage Tank and Transfer Pump Set: Temporarily stores clarified crude oil and transfers it to the next processing stage.
