Recently, Sichuan Shengma Chemical Co., Ltd. (hereinafter referred to as “Shengma Chemical”)’s 600,000 tons per year catalytic cracking unit was successfully commissioned on its first attempt, thanks to the support of advanced system solutions such as DCS, SIS, CCS, and MMS for centralized control. This marks significant progress by Shengma Chemical in moving toward efficient and green production, and it also demonstrates how Central Control Technology, thanks to its extensive industry experience and reliable technical capabilities, serves as a key driving force in the company’s transformation and upgrading process. As a leader among fuel-based chemical refining companies, Shengma Chemical always adheres to the business philosophy of \"green, low-carbon, energy-saving, and efficient\" operations. It follows a development strategy focused on excellence in refining and strength in chemical processing, striving to drive comprehensive upgrades across the industrial value chain. As the core unit of the entire plant, the compressor control system for the catalytic cracking unit has, over the years of operation, shown problems such as aging, reduced accuracy, safety hazards, and difficulties in obtaining spare parts. These issues make it difficult to meet the urgent demands of modern oil refining companies for efficiency, low carbon emissions, and sustainable development. To address these challenges, Shengma Chemical has partnered with Zhongkong Technology to carry out a comprehensive renovation and upgrade of the plant’s control systems, thereby improving equipment performance and further optimizing production efficiency. The Central Control MPS5000 vibration protection system is designed specifically for centrifugal and axial flow compressors used in process industries, offering excellent cost-performance, flexibility, and reliability. The system utilizes highly reliable industrial Ethernet technology to collect key signals such as phase angle, shaft displacement, shaft vibration, expansion difference, eccentricity, and shell vibration. It performs time-domain and frequency-domain analyses, displays the results in real time, and issues alerts based on preset parameters. Furthermore, this system is also compatible with the InPlant MP3000 monitoring and diagnostic software, enabling graphical representation of data and status analysis. It provides continuous online status monitoring, vibration protection, and fault diagnosis, meeting all the requirements of the American Petroleum Institute API670 standard. The successful first commissioning of Shengma Chemical’s 600,000 tons per year catalytic cracking unit is a perfect demonstration of how Central Control Technology delivers top-quality services to its customers through its professional skills, reliable support, and strong sense of responsibility. In the future, Zhongkong Technology will continue to uphold its mission of \"making industry smarter and helping customers achieve greater success.\" It will take on the responsibility of driving the advancement of the industry in terms of sophistication, sustainability, and intelligence. Through continuous innovation in product technologies and service models, it will provide customers with more efficient, safer, and environmentally friendly solutions. By working hand in hand with its business partners, it will help to usher in a new era of intelligent manufacturing.
Shengma Chemical’s 600,000 tons/year catalytic cracking unit
Sichuan Shengma Chemical Co., Ltd. is located in the Economic Development Zone of Daying County, Suining City, Sichuan Province, in the heart of the Chengdu-Chongqing economic circle. It is 110 kilometers away from Chengdu and 140 kilometers away from Chongqing, offering convenient transportation access. The company was founded in 1958. Following the consolidation of small oil refineries in 2000, it became the only local oil refining enterprise to remain in the southwest region (designated as No. 1095 under the State Economic and Trade Commission’s regulations on the petrochemical industry). It is a key enterprise that is being fostered by Sichuan Province, a priority enterprise in the province’s “7+3” industrial development plan for the petrochemical sector, an enterprise that plays a vital role in providing supporting resources within the province, and a provincial-level pilot enterprise for technological innovation. It is also considered a “10-billion-yuan” enterprise that is being prioritized for development in Suining City, as well as the leading enterprise in the chemical industry in Daying County. The company covers an area of over 1,950 mu and has more than 600 employees, including 53 mid-to-senior level technical personnel; 40% of the employees hold college degrees or higher. The company’s crude oil processing capacity is 3.9 million tons per year. It operates 12 production units, including ones for processing 2.4 million tons of fuel oil per year, 1.5 million tons of fuel oil per year, 1 million ton of diesel through hydrogenation per year, 600,000 tons through catalytic cracking per year, 250,000 tons through selective gasoline hydrogenation per year, 200,000 tons through non-hydrogenative reforming of C4 hydrocarbons and naphtha per year, and 20,000 tons through sulfur recovery per year. The company also has dedicated railway lines with a capacity to handle 3 million tons of raw materials per year and 1 million tons of refined products per year, along with various supporting facilities. The company is equipped with advanced production facilities. Its main products include gasoline, diesel, asphalt, liquefied petroleum gas, MTBE, polypropylene, sulfur, etc. Among these, polypropylene and heavy-duty road asphalt have been recognized as famous brand products in Sichuan Province. The company is capable of processing 3.9 million tons of crude oil per year, producing 180,000 tons of gasoline and diesel as well as 120,000 tons of asphalt each month, thus playing a significant role in supplementing the supply of petroleum products and asphalt in the southwestern region.
The first set of online condition monitoring solutions for mechanical equipment using central control technology has been successfully implemented. Finance World, 2023-09-27 19:59. Recently, the optimization and upgrade project for the control system of the No. 2 sulfuric acid gas-driven fan at Sichuan Longmang was put into operation. This unit uses a Hangzhou Zhongneng HS 23090 steam turbine to drive a Shengli SDG 160-A centrifugal blower. In this project, the MPS 5000 online condition monitoring solution from Zhongkong Technology enables real-time transmission and display of signals such as fan phase, shaft vibration, and shaft displacement. It is integrated with the T5100 dedicated control system for units, ensuring the stable, reliable, and safe operation of the system. Sichuan Longmang is a large enterprise group whose main activities involve the production and operation of phosphorus chemicals, titanium chemicals, biochemicals, as well as the comprehensive development and utilization of vanadium-titanium magnetite. It is the world’s largest producer of industrial-grade monoammonium phosphate and one of the key manufacturers of phosphate fertilizers in China. The online condition monitoring solution for rotating equipment, independently developed by Zhongkong Technology, features high-speed communication buses and a high density design, as well as card redundancy, to ensure high security and reliability of the system. It is capable of continuously monitoring in real time parameters such as phase, speed, shaft vibration, shaft displacement, eccentricity, and housing vibration of large rotating mechanical equipment. These values are compared with preset alarm and interlock thresholds; once a threshold is exceeded, an alarm interlock signal is immediately sent to the SIS and CCS to prevent the equipment from operating and thus avoid accidents. The optimization and upgrading project for the control system of Sichuan Longmang’s No. 2 sulfuric acid gas-driven fan has enabled real-time online monitoring of the fan’s operating status by integrating central control technology and equipment condition monitoring solutions, thereby ensuring safe and efficient operation. Zhongkong Technology’s equipment condition monitoring services are aimed at providing customers with superior, more efficient, and safer comprehensive solutions for managing the condition of industrial equipment on site. By offering accurate equipment diagnostics and data support, it helps to create a digital and intelligent industrial ecosystem, thereby assisting customers in achieving efficient operation and maintenance of their industrial processes as well as sustainable development of high quality.
