This simulation model is developed by using HYSYS simulator with suitable thermodynamic package chosen. In the present study, binary and multi-component distillations of saturated and unsaturated fatty acids are studied. Therefore, palm based fatty acids are selected to be used as the feed components. In South East Asia, palm tree fruit ripen continuously and can be harvested all year round. In this simulation study, the optimization of the tray specification, feed stream pressure and temperature on the purity performance of the fatty acid composition are investigated. Since desired purity of fatty acid is achievable through the most common and most efficient means of fractionation distillation process, study on simulation of fatty acids distillation has a significant contribution to the oleo chemical industry. Due to fatty acid market demand, the purity requirement of distillated fatty acid products is increasing greatly. Crude fatty acids can be obtained from the process of hydrolysis and will be purified through total distillation. Alternatively, common edible oils used are sunflower oil, corn oil, soybean oil, palm and palm kernel oil. Most of these raw materials result in nature as complex mixtures of triglycerides, alcohols and other esters. Commercially produced fatty acids are derived from naturally occurring fats and oils through the process of hydrolysis. In addition, fatty acids also play a vital role in human metabolism and are widely used as catalyst in some chemical reactions. Chemicals derived from fatty acids are widely used in the formulation of detergents, lubricant, surfactants and in pharmaceutical industries. He 2).Fatty acids have long been recognized for their commercial value in the absence of glycerol.

Van der Waals forces Van der Waals forces account for the attraction of the shifting electron-rich portion of one molecule to the shifting electron-poor portion of another molecule (temporary states of electronegativity, e.g.

Dipole-Dipole A dipole force occurs when the positive end of a polar molecule is attracted to the negative end of another polar molecule (CH 3COCH 3, propanone).

When hydrogen is bonded to fluorine, the bond is very strong, when bonded with chlorine it has moderate strength, and when bonded with another hydrogen, the molecule is non-polar and is very weak. Not all hydrogen bonds have the same strength, it depends on the electronegativity of the atom it is bonded to.

This represents a polar covalent bond in which the electrons are shared unequally.

The electron cloud around the fluorine atom is large and has high electronegativity while the electron cloud around the hydrogen atom is small and has much less electronegativity.

Hydrogen bond A hydrogen atom that is bonded to another atom by sharing its valent electron has low electronegativity (e.g.

It is this neutrality that makes the ionic bond so strong, and why it would take more energy to break that bond than a different type of bond. In the example of NaCl, the positively-charged sodium ion is held in close proximity to the negatively-charged chloride ion and the net effect is a molecule that is electrically neutral.

Ionic bond Ionic bonding involves an electron being donated from one atom to another (e.g.
