Spring has arrived in 2024, and Happy Forum is here **********************【Ten Years of Great Development in Chemical Processing Equipment】A continuously updated summary post is available; feel free to join the discussions at https://bbs.hcbbs.com/thread-3576046-1-1.html (Source: Haichuan Chemical Forum Website) ***************** On March 22, 2024, a meeting to promote the development of domestically produced high-temperature, wear-resistant ball valves for use as catalysts in Sinopec Ningbo Zhenhai Refining & Chemical Co., Ltd.’s 600,000 tons per year propane dehydrogenation plant was successfully held in Yongjia, Zhejiang. The meeting was organized by Chauda Valve Group Co., Ltd. Wang Jinfu, the chief expert from Sinopec Guangzhou Engineering Co., Ltd., Jiang Wanjun, the deputy technical director, Li Minghao, the deputy chief engineer, Wang Hanzhou, the chairman of Chauda Valve Group, Wang Ce, the deputy general manager, and Ye Jianzhong, the deputy chief engineer, attended the meeting. Sinopec Ningbo Zhenhai Refining & Chemical Co., Ltd.’s 600,000-ton/year propane dehydrogenation unit is the first PDH unit of this capacity to adopt a domestic process package based on the mobile-bed propane dehydrogenation to propylene technology (SPDH) with independent intellectual property rights. The design temperature of this process package is higher than the operating conditions of foreign mobile-bed PDH process packages, as well as higher than the design temperatures of S-Zorb units and catalyst pipelines in continuous reforming units. In China’s petrochemical industry, there are no wear-resistant ball valves of this type that can withstand such harsh conditions. Prior to this, foreign suppliers were mainly American MOGAS, Finnish NELES, etc. The focus of this localization effort is on wear-resistant ball valves with operating and design temperatures above 550°C, with the ultimate goal of developing high-temperature wear-resistant ball valves capable of withstanding 670°C. The Technology Department of Sinopec actively supports the localization of high-temperature, wear-resistant ball valves for catalyst use. It also encourages domestic manufacturers to work on technological advancements and their industrial application, with the goal of developing products with performance superior to those available abroad.
