Importance Of Extraction Process

Abstract

The purpose of this report is to research and get more wide information about one of several kinds of separation process which is the extraction process. Extraction is an important process as it is used always to extract raw materials from natural resources; therefore, the topic was chosen. This research report focused on the theory and mechanism of different types of extraction process, the applications, the challenges in industry, and the cost of the process. In fact, we have obtained most of our information from reliable online sources and scholarly articles in order to understand the concept and do original work. This report reached a conclusion that extraction separation process depends mainly on relative solubility of

This solid is called extraction in the figure below, and the desired components are called the transition component which will actually move from the solid to special solvent that is miscible with this material leaving the solid phase alone. In fact, in this kind of extraction some of the extracted components will remain in the with the solid carrier phase of the material. Therefore, the process is repeated several times to make sure that all remaining material is transmitted to the solvent. The figure below illustrated the idea of this extraction process.

Applications

• Waste-water treatments;

Extraction is used to purify water from compounds such as phenol and aniline. Etc. • Metal refining industries;

In this application, chemicals known as modifiers are used to increase the solubility of the metals formed in the solvents and suppress the formation of solids. It is used to separate precious metals from a liquor comprising salts or/and base metals. In addition, it can be used to reduce impurities of a precious metal.

• Caffeine extraction.

Of course all of us heard of the decaf coffee and many of us even have it every day. The process used to separate the caffeine from the coffee is the extraction process. It is one of the simplest and most convenient experiments to be done.

Extra applications o Neutralization/washing

The importance of it is due to its huge usage almost in every factor as the raw materials are needed to be extracted from the nature. It has main known types which are the liquid-liquid extraction and the solid-liquid extraction. The process unit of extraction consists of two inputs for the material that includes your desired component and for the solvent used to extract it in addition to two outputs for the extract and the raffinate. The mechanisms of the extraction’s two types were explained in the report above. Moreover, the applications discussed for the process are waste-water treatments, metal refining, and caffeine extraction. Furthermore, the industrial challenges faced in the process can be the disposal of the organic solvents, and the expensive glassware apparatus. Also, the cost of the extraction process differs depending on the materials
