Palm oil

Palm oil stands as one of the most critical commodities within the global oils, fats, and biofuels markets. Huading Separator offers a comprehensive range of products meticulously tailored for palm oil mills, with the core objective of addressing the diverse equipment requirements of oil extraction workshops. Our product portfolio encompasses not only palm oil separators but also decanter centrifuges specifically designed for palm oil processing applications.

Whether the application involves crude oil extraction, Palm Oil Mill Effluent (POME) treatment, biogas sludge dewatering, crude palm oil refining, or the drying processes for oleochemical products, the implementation of appropriate solid-liquid or oil-water separation techniques is essential to ensure that the final product meets established quality standards. Currently, our key recommended products include:

Nozzle separator
Decanter centrifuge
Palm oil purifier

crude-palm-oil-process-flowchart-decanter-centrifuge
crude-palm-oil-process-flowchart-decanter-centrifuge

 

Palm oil from the underflow can be recovered by either of the following systems:
━Three-phase nozzle separator
━Three-phase decanter centrifuge
━Two or three-phase decanter in combination with nozzle separator

 

Nozzle separator


The PAND nozzle separator is used for recovery of palm oil from the settling tank underflow in a palm oil mill. This underflow is commonly called sludge water. PAND nozzle palm oil separator is sometimes installed to recover oil from the heavy phase of a three-phase decanter. The decanter has removed most of the oil and there is very little left for the PAND nozzle palm oil separator. The main task is to recover the oil in the third layer. The requested separation duty here is to separate between water and water with some oil containing suspended solids.
Separation is performed in a rotating bowl containing conical discs, where in the space between each disc the actual separation takes place. The liquid feed enters the bowl through a stationary feed pipe into a rotating distributor insert in the center of the bowl and then passes into the disc stack. Solids are continuously discharged through the peripheral nozzles. The nozzles discharge leaves the machine by gravity via an outlet in the frame. Water are forced towards the bowl wall where they are discharged under pressure through the centripetal pump. The concentrated oil is pumped out by a built-in centripetal pump as well. Should the oil and water content in the bowl move outwards, with the risk of oil being ejected together with the solids, water from the overhead balance tank will automatically enter the bowl and push the oil level back to the normal position.
By removing the nozzle holders from the outside and flushing the bowl with water while running at low speed the PAND nozzle separator can be cleaned without dismantling. In this way, machine down-time is reduced to a minimum.
In addition, the PAND nozzle palm oil separator comes with a CIP program. Flushing water is initially introduced into the feed inlet tube when the centrifuge is running at low speed over a few cycles to be followed later by introducing the flushing water into the clarified light phase (recovered oil) outlet through the disc stack when it is running at higher speed.
All liquid-wetted parts are of stainless steel. The frame is made of cast iron except the top part & frame hood which are of stainless steel. As a protection against erosion, the PAND palm oil separator contains several erosion guards and liners.

 

Decanter centrifuge

The PAWT series 3-phase decanter separates the pressed crude oil mixture that comes from the underflow of the main settling tank into an oil phase, a dry solids cake and virtually oil-free wastewater. The oil phase is sent to a purifier, which polishes the palm oil and reliably removes even extremely small contaminants.

The palm oil sludge enters the rotating bowl through a stationary feed tube and is thrown radially outwards into the bowl through feed ports in the conveyor hub. By means of centrifugal force, the solids and liquids are separated from each other in the bowl.
While the solids particles settle to the bowl wall and are discharged by means of a screw conveyor, the cleared liquid phase accumulates above the separated solids phase and is discharged at the opposite end of the bowl. The oil phase and water phase pass to their respective outlets. The light liquid phase (oil) discharged by means of adjustable dip tubes by gravity, and the heavy liquid phase discharged through overflow weirs.

The PAWT series 3-phase decanter centrifuge comes with two motors, which are controlled by two separate VFD. The VFD system optimizes the differential speed without changing belts or pulleys during operation.

The PAWT decanter centrifuge offers the best wear protection. The different zones and elements in a decanter centrifuge need different wear protections. A variety of materials ensure that the operations are able to withstand high temperatures as well as heavy duty and corrosive products.
• To protect the bowl, the inner surface has strips. Bowl outlets are protected with easily replaceable hardfacing bushings.
• To protect the screw conveyor, the flights are protected with sintered tungsten carbide tiles.
• To protect the sludge discharge ports, these ports are protected with erosion resistant bushings.
• To protect the solids casing, the receiving surface has a thick stainless steel plate.

Huading Separator supply centrifugal separation solutions for all procedures and processes for recovering palm oil. The continuously operating technology combines extremely robust design with high product yield and excellent oil quality. Huading Separator decanter centrifuge cover the whole throughput range required in the palm oil industry with capacities from 30t to 100 t FFB/h.

Oil purifier
The palm oil Purifier is widely used for the purification of palm oil. The oil is fed from the oil tank to the purifier where impurities and water are removed. After purification the oil passes to the vacuum dryer, and is finally pumped to the main storage tank via an oil cooler.

The PASB purifier is a solids ejecting disc stack type centrifuge. The rotating bowl is driven by the electric motor via the flat belt or gear worm. With the feed closed, oil is displaced from the bowl by the addition of displacement water and discharge water is added to release the hydraulic closing force, lowering the sliding bowl bottom. After the discharge cycle, a new water seal is established in the bowl and separation continues. Oil is fed into the purifier by using an external pump. The operating water slide and the complete hydraulic system controlling the sludge discharges are inside the bowl. There is no possibility of contamination from external sources.

The separator bowl is designed for partial discharge of separated sludge, which means that there is a minimal loss of oil. The drive system is of belt drive, or the worm and worm wheel.
The feed system is via external pump system. No operating water tank is required as the purifier requires water at high pressure and this is achieved by an external water pump which operates only during the discharge cycle. Discharging have to be made at regular interval of 15 to 20 minutes and each discharge cycle last for a period of several seconds. The discharge system is fully automated with manual override system.

Biodiesel

Biodiesel has established itself as an alternative fuel. Oil crises and increasing environmental awareness will accelerate the current boom globally.

The use of alternative fuels is booming. Apart from bioethanol for adding to petrol, this development is due mainly to biodiesel.

There are several reasons for biodiesel’s success: rising world market prices for oil, the high taxation of conventional fuels, and an international environmental policy that specifically promotes fuels from renewable resources. In addition, the quality of biodiesel is now equal to that of conventional diesel.

Biodiesel can be extracted from virtually all vegetable oils. While rape is the most productive plant in the world, soy bean oil or palm oil are extremely important in other regions of the world. Unlike fossil fuels, whose sources are slowly but surely running out, renewable resources guarantee ‘replenishment’ with each harvest.

And irrespective of the oilseed used, all the by-products, such as bruised grain or glycerin, can be used – so ecology and the economy are in perfect harmony.

Centrifugal separators can be used in the following process stages in virtually all of the following:

━ Separation of methyl ester and glycerine/catalyst / soap/methanol
━ Washing of methyl ester
━ Separation of fatty acids from glycerine
━ Separation of salts from glycerine

TREATMENT OF DIESEL OIL

Better diesel for powerful engines – Diesel is the most important fuel for engines not only in industry but also in agriculture. But diesel is not always diesel. Especially in the tough conditions encountered in agriculture and industry, diesel is frequently contaminated with condensation water and dirt particles mainly during transportation and storage.

This problem is particularly serious in large farming operations where tractors and machinery are increasingly being used. What is the point of specifying the degree of purity of the diesel in the manual as an obligation under warranty when only low-grade diesel qualities are available locally?

The manufacturers of vehicles and engines are increasingly adopting the practice of incorporating disc separators in their offers to buyers in the agricultural sector. These machines are capable of dealing with this problem, even in extremely remote regions. The farms can therefore immediately feed the diesel oil from the tankers through a disc separator and store the purified diesel. Alternatively, the contaminated diesel could be intermediately stored and circulated through the separator later into a fresh tank.

The smallest disc separator operates at a capacity range around 1000 l/h. This amply covers the requirements of farming operations. And, since the separator is also available in a light, transportable mobile version, it can be flexibly used from farm to farm.

Huading Separator supplies practical, customized solutions not only for the agricultural sector but also for large petrol stations (for diesel locomotives and busses) and for mining.

TREATMENT OF SPENT EMULSIONS AND SPENT OIL

Spent /waste oil is generally denoted as an oil which, due to changed properties, no longer meets the original requirements (e.g. oiliness), and whose characteristics cannot be further enhanced by treatment. Potential sources are spent oils from engines and gearboxes, oily emulsions, bilge water, tank residuals etc. These waste oils have different densities, viscosities and impurity levels.

Waste oils can be treated or refined by means of chemical-physical processes or used as high-grade fuels in the cement industry or in smelters. The waste oil ordinance stipulates the priority of the material treatment of waste oils by means of refining in as far as this does not conflict with technical and economic as well as organizational constraints. The composition of the waste oil as well as the level of contaminants in the waste oil likewise determine the method of disposal.

If the waste oil is to be incinerated, all impurities such as solids and water must be removed beforehand. During incineration, the water content lowers the calorific value. The solids lead to deposits in the boiler, clogging of the nozzles and diminish the thermal efficiency.

Waste oil can be treated by means of mechanical centrifugal technology. Decanters and self-cleaning separators can be used for separating solids and water from waste oil.

TREATMENT OF LUBRICATION AND HYDRAULIC OIL

Clean oil for smooth operation – Water and dirt particles act as a catalyst for the lube or hydraulic oil used. If condensation or leakage water enters the oil through the narrow gaps of the hydraulic system, corrosion can easily result.

Apart from water, particles produced as a result of wear to the metal components as well as dust from the environment can enter the liquid. In time, the quality of the oils will be impaired by the impurities and liquid foreign matter like water which will ultimately lead to blockage and malfunctions in the system.

The result is machine failure and the associated costs for maintenance and loss of production.

The contaminated oil must be replaced with fresh oil. This creates additional costs for waste oil disposal as well as for the purchase of new oil.

To ensure problem-free functioning of the lubricating and hydraulic systems, a lube oil and hydraulic oil free from water and foreign matter must be used. With the aid of centrifugal technology, these fluids can be rid of solids and water. The separators do this very efficiently. They remove metal particles up to 1 µm.

Steel works or paper mills, for example, improve their efficiency using this kind of oil treatment.
