Red May for chemical workers! Reply rewards! ---------------------------------------------- The past ten years have been an era of great development for China's chemical industry. The emergence of many new processes, new products, and new equipment has also led to a great development in my country's chemical equipment, which has also promoted the rapid development of the petrochemical industry. Here we have collected and sorted out some of the achievements and breakthroughs made by my country's equipment companies in the large-scale and localization of equipment. Welcome everyone to share, discuss, and exchange, cheer for Made in China, and cheer for chemical equipment! ===================== The ultra-large vertical mixed feed stirred tank in the residual oil hydrogenation slurry bed device industry In November 2021, Tianhua Institute successfully started up the 580m3 mixed feed stirred tank supporting the 2×3 million tons/year slurry bed residual oil hydrogenation device of Zhejiang Petrochemical Co., Ltd.’s 40 million tons/year refining project. It has been running stably for more than 6 months. This marks the complete success of the localization task of Tianhua Institute’s task of localizing the ultra-large vertical mixed feed mixing tank (diameter 5 meters, height 38.5 meters, mixer length 32 meters, tank weight 280 tons) in the residual oil hydrogenation slurry bed device industry. The slurry bed residual oil hydrogenation technology mainly adopts the EST process developed by Italian Eni Company. This process has strong raw material adaptability and high conversion rate. It is a high-temperature and high-pressure hydrogenation reaction of inferior heavy oil/resid oil in the presence of hydrogen and catalyst. It has obvious advantages in processing inferior heavy oil with high metal content, high carbon residue, and high viscosity. The liquid product yield of slurry bed residue oil hydrogenation technology using this process can be as high as 80% to 90%.
