Abstract
Paraffin deposition is a severe global problem during crude oil production and transportation. To inhibit the formation of paraffin deposits, the commonly used methods are mechanical cleaning, coating the pipe to provide a smooth surface and reduce paraffin adhesion, electric heating, ultrasonic and microbial treatments, the use of paraffin inhibitors, etc. Pipeline coatings not only have the advantages of simple preparation and broad applications, but also maintain a long-term efficient and stable effect. In recent years, important progress has been made in research on pipe coatings for mitigating and preventing paraffin deposition. Several novel superhydrophilic organogel coatings with low surface energy were successfully prepared by bionic design. This paper reviews different types of coatings for inhibiting wax deposition in the petroleum industry. The research prospects and directions of this rapidly developing field are also briefly discussed.
Highlights
Crude oil is known as “black gold” and is called as “the blood of modern industry.” It benefits human beings in terms of energy, and is a very important chemical raw material
In the early research into coatings for paraffin deposition control, the researchers believed that smooth surface or low surface energy coatings can effectively inhibit paraffin deposition
In the modern petroleum industry, the most advanced techniques of low surface energy anti-wax coatings have been put into practice
Summary
Crude oil is known as “black gold” and is called as “the blood of modern industry.” It benefits human beings in terms of energy, and is a very important chemical raw material. Wax deposition in the inner wall of petroleum pipelines will cause the effective flow area to be reduced or blocked, increasing the flow resistance and pump loads and affecting the service life of equipment such as sucker rods. This will reduce the efficiency of work, resulting in huge economic losses, and damage the operating equipment. Mechanical cleaning uses a special scraper to remove paraffin and soft wax deposits from the inner wall of the pipeline. The research prospects and directions of this rapidly developing field are briefly reviewed
