In order to promote the high-quality development of China's petroleum and chemical industry, the National Petroleum and Chemical Technology Innovation Conference was grandly held in Hangzhou from December 23 to 24, 2020. The key technology for ultra-high performance corrosion resistance and anti-coking of stainless steel surfaces in harsh environments" was granted the "Second Prize for Science and Technology Progress Award of China Petroleum and Chemical Industry in 2020".
The key technology for ultra-high performance corrosion resistance and anti-coking of stainless steel surfaces in harsh environments (CTS technology) was a complete set of industrialized technologies for ultra-high performance corrosion resistance and anti-coking on stainless steel surfaces, which was developed by the research team composed of Shenzhen Candor Technology Co., Ltd., SEI, LPEC, Beijing University of Chemical Technology, and many refining and chemical companies over 27 years of endeavor.
CTS technology aims to obtain a high-adhesion, large-thickness, densified film layer, using a stainless steel substrate through a chemical-electrochemical combined method. It prepares a high Cr+O content film layer on the surface of austenitic stainless steel to improve corrosion resistance while achieving low Fe and Ni content to improve anti-coking performance.
At present, CTS technology has been applied to 14 types of plants under harsh operating conditions such as high acid, high sulfur, and high chlorine. The surface-strengthened stainless steel material extends the service life by more than 2 times. It greatly improves the corrosion resistance and coking resistance of stainless steel, allowing low-grade materials to replace high-grade materials in terms of corrosion resistance. It also improves the process effects of refining equipment and creates huge economic benefits and social value. This is an internationally leading technology in the field of corrosion resistance and anti-coking of stainless steel materials for petrochemical applications, it is also a "Created in China" technology.。
