Stearic Acid Process Flow Diagram
Schematic diagram of the process flow of stearic acid
Stearic acid, as a common fatty acid, its production process is very important. The following will show you the process flow of stearic acid.
In the initial stage, high-quality animal and vegetable oils need to be selected as raw materials. This raw material is rich in triglycerides and is the basis for the formation of stearic acid. Put the selected oils into the hydrolysis reactor, and add an appropriate amount of catalyst and water at the same time. Under suitable temperature and pressure conditions, the oils and water undergo hydrolysis reaction. Triglycerides are gradually decomposed to form fatty acids and glycerol. During this process, the temperature is usually controlled at about [X] degrees Celsius and the pressure is maintained at [X] MPa to ensure the efficient progress of the reaction.
After the hydrolysis is completed, the resulting product is a mixture of fatty acids and glycerol. Due to the difference in density and boiling point between the two, the preliminary separation can be achieved by static stratification or distillation. Glycerol is denser and will sink to the bottom, while fatty acids are in the upper layer. The separated fatty acids are further sent to the rectifying column. The rectifying column performs fine separation according to the different boiling points of different fatty acids. Stearic acid has a relatively high boiling point. At a specific temperature range, high-purity stearic acid vapor can be collected from the corresponding position of the rectifying column. After the steam is cooled by the condensing device, it is converted into liquid stearic acid and flows into the storage tank for backup.
During the whole process, the quality inspection link runs through. Strict testing is carried out on each step of the product to ensure that the purity, color, acid value and other indicators of stearic acid meet the standards. If abnormal indicators are found, the process parameters are adjusted in time to ensure the stability of the final product quality. In this way, through a series of rigorous technological processes, high-quality stearic acid can be produced and widely used in many fields.
