Fractionation Plant With Highest Efficiency & Returns The Mectech Advantage

Dry Fractionation is employed to separate the dry Glycerides with high melting points from the low melting point ones by employing crystallisation. Either by adding heat (distillation) or removing heat (condensation, the processing plant separates hydrocarbon mixtures based on the vapor pressures of its component molecules. The by-products include propane, butane, and ethane. Being a physical modification of the palm oil, The palm oil fractionation process is designed to separate palm oil into two fractions- Olein and Stearin. This is custom designed as a physical process and occurs without the addition of any chemical or solvent. Mectech’s fractionation plants are failsafe and depended upon to produce stable and filterable crystals consistently such that the market demands can be fulfilled with products that meet  or exceed every quality  standards and  requirements. It thus ensures continued returns for your investments. Mectech's bio-diesel system innovates technology and is versatile enough to be used in different kinds of fresh vegetable oils (e.g. sunflower, rape seed oil, palm oil) but also fats.  

PALM OIL FRACTIONATION PLANT  

Mectech's crystallizers utilized for fractionation incorporates a cooling coil with customized design in order to provide a large cooling surface area. This leads to formation of better crystal nuclei on which crystals are grown and hence perfect crystals. The slowness of the agitation and agitator configuration is designed to maintain the oil mass moving without stagnation even when it is nearing the cooling stage. The crystals developed during the process separated by employing  a membrane filter press enabling  the squeezing out of the stearin cake to optimize the extraction of liquid olein. 

 PALM OIL FRACTIONATION PROCESS  

The multi-step process consists of: 

  

·            Heating the feed oil 

·            Formation of crystals by controlled cooling 

·            Crystal growth 

·            Maturation of crystals 

·            Filtration to separate Olein and Stearine 

  

The desired quality of R.B.D. Palm oil obtained after passing through various processes is pre-heated to about 70^o C to obtain a homogeneous entity without any solid mass. Mectech has innovated a PHE through which the oil temperature can be maintained as desired. Oil is fed continuously and the flow rate controlled by utilizing  an oil flow control valve. In the 1^st and 2^nd crystallizers cooling is achieved by adding ordinary water- directly from the cooling tower at a temperature of 32°C, thus optimizing the inputs and lowering process costs. Cooling in the 3^rd and 4^th crystallizers is accomplished with chilled water, made available from the vapor absorption chiller at 7^o C. 

During the cooling sequence, samples are taken at regular intervals from the crystallizer for analysis of their physical behaviour. The physical properties of the olein and stearin fractions, such as cloud point, slip melting point and solid fat content are dependent on the crystallization temperature. On-flow crystallization method ensures that  the cooling and crystal formation has been attained in all the crystallizers.   The flow continues through compensator to the filter in absence of any energy source – through gravity.  Oil from the compensator is filled in the membrane filter by gravity and after attaining a pressure of 1.5 – 2 kg/cm²,  the filter pump is designed to  start. For filtering the olein from the filter press, all operations such as opening, closing, squeezing and washing and discharge of the stearin to the stearin melting tank are automated and computerised. This optimizes the process ensuring not only greater returns but consistency of quality and failsafe operations.  

  

MAIN FEATURES AND ADVANTAGES OF FRACTIONATION

Mectech Vegetable Oil Refining Plant Brings Efficiency & Greater Returns

In its crude form, the oil is permeated with impurities, that must be eliminated not only to make it edible, but also to enhance the color, texture and taste and prevent rancidity. The multi stage process that eliminates these impurities & attracts consumers with taste and acceptability to earn greater returns is called refining. The crude oil must necessarily undergo the refining process to remove the inherently harmful elements for human consumption including free fatty acids (FFA), gums, sediments, odoriferous and coloring materials present to make the oil edible. 

Some of the impurities present in the Oil are: 

Gums: These phospholipids are of two types: hydratable and non-hydratable. The Hydratable gums are eliminated during degumming process.  

Hydrolysis Products of Oils:  Diglycerides and monoglycerides and free fatty acids are produced during hydrolysis and are removed during neutralization . 

Proteineous Matter, Carbohydrates, Resins: Are eliminated during neutralization step. 

Pigments : Coloring Matter including  chlorophyll (green colour) carotene (red colour), anthophyll (yellow colour) and gossypol (orange colour) impart distinctive  colour to the oil and need to be  removed. 

Odorous Chemicals: Occurring in small quantities, their presence makes the product detestable by imparting pungent and even unacceptable odour. These volatile substances are removed during deodorization. 

Waxes:  Waxes are characterized as  high melting esters of fatty alcohol with long chain fatty acids  are eliminated through  dewaxing . 

MECTECH undertakes the multiple steps needed – often in combination at all the stages. After undergoing the process of neutralization, bleaching and deodorization, the oil is made safe and fit for human intake. Through inimitable innovation and customization, value adds optimization into each process to enhance the processes and returns. 

The various steps undertaken for refining vegetable oils are:  

  

Degumming / Neutralization 

The process of eliminating the embedded phospholipids in order to enhance its physical stability and facilitate further refining is called degumming. Phospholipids turn the oil lead dark and even off -flavor. Free fatty acids, pigments and other impurities are also partially removed by degumming. 

  

Mectech has revolutionized the degumming processes by incremental enhancements. These processes are customized according to the methods of processing, chemicals used and the content of phosphatides in the crude vegetable oil.  

  

Continuous Bleaching 

“Bleaching” is  the  selective elimination  of pigments and impurities through interacting it  physically  and chemically with  an adsorbent in order  to enhance  its quality. It eliminates various impurities like Color pigments, Dirt, Trace metals, Removal of polycyclic Aromatic compounds, Phospholipids. 

  

MECTECH's customized design of bleacher eliminates the need for mechanical agitation. Hence bleaching is accomplished under optimum conditions of moisture content to achieve perfect results ensuring power consumption saving for the entire system. 

With the absence of mechanically agitated bleacher, the quality of oil improves due to lack leakages from gland system. It also eliminates maintenance costs arising out of  wear and tear as the  Mectech bleacher is maintenance free. 

Mectech’s customized bleacher also ensures that the bleaching earth remains under suspension thus avoiding dead areas, resulting  in lower consumption of bleaching earth. Moreover, due to the  bleaching process being  executed  under controlled parameters, better and consistent quality of resultant oil is guaranteed, that is crucial to its marketability.  

Deodorization 

In this vacuum stripping process, a given amount of a stripping agent (usually steam) is passed for a given period of time through hot oil at a low pressure. The physical process removes various volatile components. The customized Mectech designed oil-to-oil heat exchanger fitted in the last tray of Deodorizer is optimally efficient to ensure minimum heat energy requirement. The elaborate and efficient design of fatty acid scrubbing recovery system ensures virtually no transfer of fatty acid into barometric condenser. The most custom designed heating coil by Mectech prevents charring of oil during the process.
