We use American RCS products, while those produced by Metal Institute are imitations of foreign ones, and their price is even higher than that of foreign products

I’m not sure which company on Blue Star Four An is working for; I’d really like to exchange ideas on this.

Recently, an online corrosion monitoring system that combines measurement, analysis, and recording functions was successfully put into use at the Yangzi Petrochemical Refinery, providing the plant with another useful tool in its efforts to mitigate the effects of corrosion caused by high-sulfur and high-acid crude oil. 　　In recent years, the proportion of high-sulfur and high-acid crude oils processed by refineries has been increasing, which has significantly reduced the cost of purchasing raw materials. However, this also poses potential corrosion risks to the equipment. To ensure the long-term stable operation of the units, the refinery, in accordance with the three-year plan for processing high-sulfur crude oil and taking into account the characteristics of each unit, has continuously carried out corrosion prevention monitoring and control measures, achieving very good results. The online corrosion monitoring system used this time is a new technology developed by the Institute of Metal Research, Chinese Academy of Sciences; it has been put into practice in some enterprises with favorable results. Since the measurement probes required for online monitoring must be installed during periods when the plant is shut down, the refinery began preparing for research and project initiation at the start of this year, in line with its maintenance plan, and received strong support from the relevant departments within the company. The two vacuum distillation units have been in continuous operation for 4 years. During this shutdown for major maintenance, the plant installed 11 monitoring probes at the tops of the towers, on the air coolers, and in other locations. These probes are divided into three different types based on the nature of the parameters they measure: resistance, inductance, and pH value. They operate at different monitoring frequencies, allowing for accurate and timely assessment of the process conditions, properties of the fluids, and levels of corrosion. The data is displayed on specialized monitoring software, and can be accessed at any computer terminal connected to the network throughout the plant, thereby enabling better guidance for daily operations in areas such as \"one distillation and three injections.\" This enhances the plant’s ability to control equipment corrosion. In recent years, the Dushanzi Petrochemical Branch of China National Petroleum Corporation has processed an increasing amount of Kazakhstani crude oil with high sulfur content, resulting in corrosion of its production facilities. By analyzing the data from the corrosion monitoring points of the production units, it was decided to establish an online corrosion monitoring system at the key corrosion-prone areas of these units. This allows for rapid assessment of changes in corrosion levels across various units, providing early warning information to support safe production and prevent various corrosion-related leakage incidents. This online corrosion monitoring system currently includes 21 monitoring points for refining units and 39 monitoring points for chemical processing units, covering the areas of major refining and chemical plants where corrosion is likely to occur. Introduction to the Corrosion Monitoring Department of the Institute of Metallurgy, Chinese Academy of Sciences. The Institute of Metallurgy, Chinese Academy of Sciences was established in 1953; it was one of the first institutes founded by the Chinese Academy of Sciences after the founding of the People’s Republic of China.
