SGL Group Completed Delivery of Large-scale DIABON® Graphite Equipment to Wengfu Group
|• Biggest graphite columns ever built
• Enables large-scale production of food-grade phosphoric acid
Shanghai, October 25, 2012. SGL Group- The Carbon Company-announced that it has completed the delivery and installation of large-scale DIABON columns to Wengfu (Group) Co., Ltd (Wengfu). These graphite columns will be installed in Wengfu's wet process purification plants of food grade phosphoric acid, which are located in its production bases in Dazhou, Sichuan Province and Shanghang, Fujian Province with planned annual capacity of 150,000 and 100,000 tons, respectively.
Wengfu is a major player in the global phosphate chemical industry and the leading phosphoric acid producer in China. In 2005, Wengfu set up large capacities to produce phosphoric acid based on a wet purification process. The successful launch of this project marked China's debut in advanced wet process phosphoric acid industry. In 2007, Wengfu has extended its in-house phosphoric acid activities to the higher quality of food-grade acid.
"We are excited to provide Wengfu with this advanced technology solution. It incorporates the biggest columns made of graphite we have ever built with more than 2.6 m diameter and up to 20m height. The equipment is designed to cope flawlessly even with extreme process conditions, to enable higher flow rates and to eliminate completely the risk of reverse diffusion which is crucial in production of food-grade phosphoric acid. We have been able to produce and deliver the equipment in record time due to close cooperation between our two production sites in Meitingen/Germany and Shanghai/China.". said Frank Wittchen, Chairman of BU Process Technology, SGL Group.
This landmark project is another example of SGL's strong commitment to the Chinese market and cooperation with industry leaders. The efficient phosphoric acid purification processes enables Wengfu to produce the highest quality acid, which is a stringent necessity in food applications. DIABON® graphite columns with excellent corrosion, heat and vacuum resistance and a long service life minimizes downtime, extends maintenance intervals, and enables low total cost of ownership. In addition, sustainable column operation reduces energy and material consumption, bringing both economical and environmental benefits to the company.
According to the 12th Five Year Plan, China plans to accelerate industry restructuring and technological upgrading to fuel a more sustainable economic growth with lower energy consumption and less emission. The Wengfu project is a perfect example which fits to this plan.
