De-waxing is inherently a separation process which makes use of de-asphalted oil as well as heavy vacuum gas oil obtained from the vacuum distillation tower. The de-waxing process aims to remove hydrocarbons that may increase the pour point of the lubricating oil base stock to the required range and leverage the phenomenon. The de-waxing process involves two separate categories of solvent de-waxing and catalytic de-process. Solvent de-waxing is physical process which makes use of refrigeration and scraping techniques involving methyl ethyl ketones and propane solvents in order to separate the feedstock and produce products of use. A series of refrigeration processes are involved in the solvent de-waxing process that lead to the formation of crystals which are separated from the oil+solvent. The soil is used for producing candles and petroleum jelly while the de-waxed oil is used as the desirable lube oil base stock. Catalytic de-waxing on the other hand is a chemical process which is inherently a conversion process involving catalytic cracking of n-paraffin. However, it is still classified as a separation process as it allows the removal of the unnecessary wax from the oil streams. De-waxing oils through catalytic processes leads to products with lower pour points, better yields and stability as well.

Course Details

In this petroleum de-waxing online training course, a small yet very essential part of the entire petroleum refining and petroleum products production is elaborated upon. Through this course, the entire de-waxing process is explained in detail along with the applicative understanding of the subject based on hands-on approach. An amalgam of chemistry and petroleum engineering is involved in the course to provide in-depth understanding of the subject. The de-waxing process types and the knowledge of various types of solvents and chemicals used in the process are provided in detail for the benefit of the students. This course provides a small segment of a large petroleum refining process and is taught from scratch.
