Paraffin production
Paraffin is a mixture of saturated hydrocarbons with a high number of carbon atoms that is found in liquid, colloidal, or solid and crystalline form. Paraffin, which is present in crude oil, is liquid and turns into solid form through distillation at high temperatures. Paraffin is widely used in industry due to its neutral properties and is used as one of the most widely consumed raw materials in the pharmaceutical and cosmetic industries, rubber and matchmaking industries, and the production of waterproof fabrics and paper.
Ava Espikoo Sanat Company, utilizing state-of-the-art technologies and its expert team, has the ability to design and build paraffin production plants with the highest quality and productivity.
Paraffin production process
Paraffin is produced from crude oil derivatives and its production process is as follows:
-
Crude oil extraction:
Crude oil is extracted as a raw material from underground sources and transported to refineries. -
Crude oil refining:
In the refinery, crude oil is separated into various components such as gas, gasoline, kerosene, oil, and wax through distillation processes in distillation towers. -
Wax extraction:
Wax is separated from heavy petroleum oils. This process is carried out using separation techniques such as cooling and the use of chemical solvents (such as MEK and toluene). -
Separation of wax from oil (Dewaxing):
The wax obtained from the previous step in the wax separation process is separated from the remaining oils to produce slack wax. -
Wax purification:
Raw wax is refined and impurities are removed through chemical and physical processes such as acid treatment, hydrogenation, and filtration. -
Shaping and packaging:
Refined wax is converted into final products such as solid, liquid, or granular paraffin and marketed in appropriate packaging.

Production stages
Dewaxing operation:
Wax separation operations are an integral part of modern industry, and powerful industrial countries such as Canada, Germany, Austria, and Poland are pioneers in this field. The common method in these countries is to use solvents such as MEK and toluene. In this process, the waxy material is heated to a temperature of 60-70 degrees Celsius and the mentioned solvents are added to it. Then, the system is cooled using a chiller and special filters are used to separate the oil from the wax. After that, the process of solvent extraction from the oil and wax begins. This process is carried out using a distillation column. The result of this work is the production of wax from an oil with a wax percentage of less than 3% and an oil with a pour point between 0 and -2.
After reviewing various pilot projects and consulting with leading domestic and foreign engineers, we have succeeded in developing a new method in this industry. In this process, the solvent is completely removed from the system and the entire process is carried out by applying temperature cycles and reverse pressure using special devices. The purpose and reason for inventing this process is that the aforementioned solvents are not available in our country, and importing these solvents has high costs and leads to dependence on foreign countries and other industries. Therefore, with this method, we have been able to resolve these problems and exploit our country’s domestic resources.
In the remainder of the article, the wax separation process will be fully described and a schematic view of the production process will also be presented.
