【Major Chemical Equipment】040 – The World’s Largest EOEG Washing Tower

Thread Content

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 discuss these topics together; let’s cheer for Made in China and support the development of chemical processing equipment! *********************************** On March 8, 2020, the world’s largest EOEG scrubber was completed and delivered. The successful delivery of this equipment marks a new milestone for Zhanghua Machinery in the production of ultra-large diameter, ultra-high tonnage composite plate equipment. During the fight against the COVID-19 pandemic, Zhang Huaji focused on both epidemic control and the resumption of production, resulting in successive good news from the production center. The equipment delivered this time has a diameter of 9.1 meters, a length of 102.4 meters, and a total weight of 2,000 tons. During the production process, the workshop overcame the challenges associated with protecting the inner walls of towers made of ultra-large-diameter composite materials, the complexity of the internal components, and the stringent requirements for degreasing and pickling. It carried out production in strict accordance with the process specifications, and successfully passed the joint inspections conducted by the third-party supervisors, owner’s representatives, and EPC quality control teams. Especially regarding the degreasing process for the inner wall composite layer, the production workshop worked closely with the process engineering department to jointly develop and implement the relevant process procedures, thereby filling the gap in processes for chemical degreasing of the inner walls of large composite plate-based equipment.
