Palm Oil Clarification Tank

In the crude palm oil (CPO) production process, the palm oil clarification tank plays a vital role in bridging the pressing stage and the subsequent refining stage. Based on extensive industry experience and customer feedback, Henan Glory Company manufactures vertical palm oil clarification tanks, which have become the core guarantee for protecting downstream refining equipment and ensuring high-purity crude palm oil, thanks to their outstanding sedimentation performance and robust structural design.

1. Core Objectives & Function of Palm Oil Clarification Tank

The palm oil clarification tank is designed to achieve three core objectives:

(1) Gravity-Based Sedimentation:

The palm oil clarification tank utilizes the principle of gravitational settling. It allows heavier solid particles (sediments, sand, and grit) to naturally sink to the bottom of the palm oil clarification tank, while the lighter palm oil remains at the top.

(2) Protection of Downstream Machinery:

Abrasive sand and grit are the primary causes of premature wear in high-speed centrifuges, pumps, and heat exchangers. This palm oil clarification tank serves a protective function for the equipment, removing these impurities early to extend the lifespan and maintain the efficiency of refining equipment.

(3) Improvement of Crude Palm Oil Quality:

By eliminating sediments and insoluble solids, the palm oil clarification tank ensures that the crude palm oil entering the storage or refining stage has a lower dirt content, which translates to higher final oil quality and reduced refining losses.

2. Structure & Working Principle of Palm Oil Clarification Tank

Henan Glory Company's palm oil clarification tanks feature a scientific and robust design:

(1) Main Structure:

The palm oil clarification tank is designed as a vertical cylindrical vessel with a conical bottom, constructed from high-strength carbon steel or stainless steel (SS304), equipped with anti-corrosion coatings to withstand the viscous and slightly acidic nature of crude palm oil.

(2) Heating System (Crucial):

The palm oil clarification tank is equipped with a steam coil. This heats the crude palm oil, reduces its viscosity, and facilitates effective separation.

(3) Oil Inlet:

The oil inlet is located in the lower middle part of the palm oil clarification tank, ensuring that the incoming oil flows evenly and gently across the cross-section of the palm oil clarification tank, thereby maximizing settling efficiency.

(4) Clean Oil Outlet:

The clean oil inlet is positioned on the upper side of the palm oil clarification tank, this outlet collects the lighter, clarified oil that has risen to the surface, allowing it to overflow or be pumped to the next stage.

(5) Sludge & Sand Discharge System:

The system is located at the lowest point of the conical bottom, this system includes a heavy-duty discharge valve. Settled sand and sludge are periodically drained from this point, preventing buildup inside the palm oil clarification tank.

3. Key Features & Benefits of Palm Oil Clarification Tank

(1) High-efficiency sedimentation:

The vertical design of Henan Glory's palm oil clarification tanks allows for higher sedimentation heights and longer residence times. Heavier impurity particles have a longer settling distance, ensuring they are trapped at the bottom of the tank rather than carried away by the oil flow.

(2) Space-Saving Footprint:

Henan Glory's palm oil clarification tanks occupy less floor space in the palm oil mill, which is a crucial advantage when integrating into existing palm oil production lines.

(3) Excellent Compatibility:

The palm oil clarification tank can be integrated with a vibrating screen and a plate filter to form a highly efficient crude oil clarification system. The palm oil clarification tank settles and removes larger sand particles and gravel, the vibrating screen removes finer suspended solids, and the plate filter performs fine filtration to achieve high clarity. This progressive filtration method maximizes overall efficiency and protects downstream equipment from abrasive particles, ensuring oil quality.

Highly efficient crude oil clarification system
