Reply reward! ---------------------------------------------- The past decade has been a period of rapid development for China’s chemical industry, marked by the emergence of many new processes, products, and equipment. There has also been significant progress in China’s chemical processing equipment, which has contributed to the swift advancement of the petrochemical sector. Here, we have compiled some of the achievements and breakthroughs made by Chinese equipment manufacturers in terms of larger-scale production and greater use of domestic equipment. We invite everyone to share their insights and engage in discussions, to cheer for Made in China and to support the development of chemical processing equipment! ****************** Maoming Gravity Petrochemical Equipment Co., Ltd. completed the manufacture of China’s first large vertical flexible tube sheet quench heat exchangers and other related equipment, ensuring the successful commissioning of the 1 million tons per year ethylene production unit in Sinochem Quanzhou’s 1 million tons per year ethylene and refinery expansion project. It is reported that Maoming Gravity Company supplied a large number of high-tech equipment for the Sinochem Quanzhou project, including 3 pyrolysis furnaces, 56 first-stage quench heat exchangers, 7 second-stage quench heat exchangers, and one loop reactor with 16 straight legs. These equipment manufacturing tasks involve some of the most technologically advanced petrochemical equipment, both domestically and internationally. In addition to the quench heat exchangers, the other 3 cracking furnaces manufactured by Maoming Gravity also represent the highest standards in the international industry. Each of these 3 pyrolysis furnaces weighs 1,140 tons; each furnace consists of 1 radiation section module and 9 convection section modules, and once these modules are assembled, the total height of the equipment is 51.5 meters. It utilizes the world’s most advanced KBR process technology, designed by SEI, and is the largest furnace equipped with a KBR process package in China. Requiring the overall modular delivery of the radiation section poses a significant challenge in terms of production, manufacturing, and transportation. It is reported that for the Sinochem Quanzhou project, Maoming Gravity Company deployed its best team as early as 2018, organizing production day and night. Starting from early 2019, the relevant equipment was gradually delivered to the construction site in Quanzhou. All of the equipment was completed to high standards and on schedule, ensuring a successful commissioning of the system.
