Distillation columns is one of the most common liquid-liquid separation processes, and can be carried out in a continuous or batch system. For these process used is continuous system. Distillation can be used to separate binary or multicomponent mixtures. Many variables, such as column pressure, temperature, size, and diameter are determined by the properties of the feed and the desired products. As in these process, the reaction is between lauric acid and sodium hydroxide to produce the sodium laurate and water. Although packed bed columns are used most often for absorption, they are also used for the distillation of vapor-liquid mixtures. The packing provides a large surface area for vapor-liquid contact, which increases the column's effectiveness. The feed mixture contains components of different volatilities, and enters the column approximately at the middle. The liquid flows downward through the packing, and the vapor flows upward through the column. The plate or tray column is the most widely used type of distillation column. The number of trays or stages in the column is dependent on the desired purity and difficulty of separation. The number of stages also determines the height of the column. For these distillation column, the orientation is vertical because the product which will flow out in the forms of liquid and vapor. For upper stream, the major will flow out is water in the form of vapor while downstream the major which is flow out is sodium laurate in the form of liquid. Then, the material of construction (MOC) used for built the tower is stainless steel. These is because in the reaction happens between alkaline and

acidic. Furthermore, the stainless steel is long lasting and slow rusting than the other materials. For the pressure used is 101.3 kPa, which is in ambient pressure. The temperature used is 260˚C because the fluid enters the distillation column is from the exchanger. For accessories, provide stairs to the distillation column.
