Powering the Next Generation of Oil Refineries

The global demand for edible oils, palm oil products, and renewable fuels continues to rise. To remain competitive, oil mills and refineries need high-efficiency vegetable oil refinery machines that ensure superior quality, energy efficiency, and long-term reliability.

We design and supply advanced oil refinery equipment and complete turnkey oil processing plants, engineered to deliver consistent performance for small, medium, and large-scale operations.

Our Core Oil Processing Solutions

Our vegetable oil refinery machines convert crude oil into Refined, Bleached, Dewaxing and Deodorized (RBD) oil suitable for food-grade and industrial applications.

• Degumming (Water / Acid / Enzymatic)

• Neutralization (Chemical & Physical Refining)

• High-Efficiency Bleaching

• Winterization/Dewaxing (Only for Oils Containing Waxes)

• Advanced Deodorization

Vegetable Oil Refining Process – Advanced Technology by PEMAC Projects

PEMAC Projects offers customized refinery configurations based on oil type, capacity, and product quality requirements.

1. Degumming – Oil Preparation

Degumming removes phospholipids, gums, trace metals, and impurities that impact oil stability and color.

PEMAC Degumming Systems Offer:

• Water, Acid & Enzymatic degumming

• Lower oil losses

• Improved downstream refining efficiency

• Ideal preparation for physical & chemical refining

2. Neutralization – Free Fatty Acid (FFA) Reduction

In chemical refining, FFAs are neutralized using alkali under precise control.

Key Advantages:

• Accurate caustic dosing

• Reduced soapstock losses

• High neutral oil recovery

• Soapstock recovery for acid oil or biodiesel

3. Bleaching – Color & Contaminant Removal

Bleaching removes pigments, oxidation products, soaps, and trace contaminants.

PEMAC Bleaching Technology Delivers:

• Superior oil color improvement

• Low bleaching earth consumption

• Reduced oil retention losses

• Enhanced shelf life and stability

4. Winterization – Clarity & Cold Stability Enhancement

Winterization is a critical process for oils that contain waxes or high-melting triglycerides, such as sunflower oil, rice bran oil, and other specialty blends.

Winterization Process Explained:

• Controlled cooling of refined oil

• Wax crystallization under optimized temperature profiles

• Efficient separation using filters or centrifuges

• Production of crystal-clear oil with excellent cold stability

Benefits of PEMAC Winterization Systems:

• Improved oil clarity at low temperatures

• Prevention of haze formation during storage

• High wax separation efficiency

• Low oil loss and energy consumption

Winterization ensures the final oil meets consumer expectations and export quality standards.

5. Deodorization – Final Purification & Flavor Improvement

Deodorization removes odors, flavors, and volatile compounds using steam stripping under vacuum.

PEMAC Deodorizer Advantages:

• Physical & chemical Refining options

• Energy-efficient heat recovery

• Low trans-fat formation

• Premium taste, odor & shelf life

Vegetable Oil Refining Process with By-Product Valorization

Modern edible oil refining focuses on producing high-quality oil while maximizing value from every processing stream. PEMAC Projects designs advanced vegetable oil refinery plants that integrate refining operations with by-product recovery systems, ensuring higher profitability and sustainable operations.

Step 1: Degumming – Gums to Lecithin

Degumming removes phospholipids, gums, and trace metals from crude oil, improving oil stability and downstream processing efficiency. The recovered gums are not discarded; PEMAC’s High Tech lecithin plants that process these gums into food-grade, feed-grade, or industrial lecithin, widely used in food, pharmaceutical, and feed industries.

Step 2: Neutralization – FFA Removal & Soapstock Utilization

In chemical refining, free fatty acids are neutralized using controlled alkali treatment. This process generates soapstock, which PEMAC systems recover and further convert into acid oil or biodiesel feedstock in Pemac’s Advanced Soap Stock Splitting Plant reducing effluent generation and increasing overall plant revenue.

Step 3: Bleaching – Color Improvement & Oil Loss Control

Bleaching removes pigments, oxidation products, and residual impurities using activated bleaching earth. PEMAC’s bleaching systems are designed to minimize oil retention in spent earth, improving oil recovery while ensuring excellent color and oxidative stability. Further Residual oil on Spent Earth can be recovered in Pemac’s Spent Earth Recovery Plant.

Step 4: Winterization – Wax Removal for Clear, Stable Oil

Winterization is essential for oils containing waxes, such as sunflower, rice bran, and cottonseed oil. Controlled cooling crystallizes waxes, which are then separated to produce clear, haze-free oil with improved cold stability. Residual oil in waxes can be recovered in Pemac’s Wax Press Machine and Recovered waxes can be utilized for industrial and specialty applications.

Step 5: Deodorization – Final Refining & Distillate Recovery

Deodorization removes odors, flavors, and volatile compounds under high vacuum using steam stripping. This step produces premium refined oil and valuable fatty acid distillates, such as PFAD in palm oil, which are used in oleochemical, soap, and biodiesel industries.

Integrated Value Addition by PEMAC Projects

By combining refining, lecithin recovery, acid oil processing, winterization, and distillate handling, PEMAC Projects transforms refining by-products into profitable resources. This integrated approach delivers higher yield, lower operating costs, and future-ready edible oil plants that meet global quality and sustainability standards.

Palm Oil Refinery – A Proven Example of PEMAC Excellence

Palm oil requires specialized refining due to its unique fatty acid profile and large processing volumes.

PEMAC Palm Oil Refinery Process Includes:

• Crude Palm Oil (CPO) pretreatment

• Degumming & bleaching

• Physical deodorization

• Palm Fatty Acid Distillate (PFAD) recovery

Key Benefits:

• High-quality RBD palm oil

• Maximum PFAD recovery for oleochemical & biodiesel use

• Low oil losses and stable continuous operation

Oil Palm Fractionation Plant – Value Addition Beyond Refining

To unlock higher margins, PEMAC Projects Offers Oil Palm Fractionation Plants that separate refined palm oil into high-demand fractions.

Fractionation Output:

• Palm Olein – Liquid cooking oil
• Palm Stearin – Solid fat for bakery, margarine & food industries

PEMAC Fractionation Technology Features:

• Dry fractionation process

• Controlled crystallization

• High separation efficiency

• Minimal utility consumption

Fractionation enables Business Owners to diversify products, improve profitability, and serve multiple markets.

Conclusion

The edible oil and biodiesel industries demand high-efficiency refinery equipment and fully integrated processing plants to remain competitive, compliant, and profitable. Whether developing a palm oil refinery, vegetable cooking oil plant, oil palm fractionation unit, or biodiesel production facility, selecting the right EPC partner is critical to long-term success.
