MAN Energy Solutions has completed the world's largest salt-operated reactors for a new maleic anhydride plant for the production of biodegradable plastic. The three reactors, each weighing 655 metric tons, have now been loaded onto the 135m long Danube ship Excelsior at the MAN Energy Solutions site in Deggendorf in Germany. From there, the reactors will first be transported via the Danube to the Romanian port of Constanta, from where they will then reach their destination in the Chinese city of Yantai in Shandong province by ocean-going vessel.The customer is Wanhua Chemical Group, a leading supplier of chemical products in China, which will use the three salt bath reactors to produce maleic anhydride. This chemical product is in turn required for the production of PBAT (polybutylene adipate terephthalate), a raw material for biodegradable plastics. With a total capacity of 200,000 metric tons per year, Wanhua will start up one of the world's largest production plants for maleic anhydride.The salt-operated reactors each measure nearly 7m in height and around 12m in diameter. Each reactor consists of 38,500 tubes. The power consumption of the system is optimized and a higher efficiency of the process is achieved through an optimized tube diameter, which leads, among other things, to a lower pressure drop across the catalyst bed. The reactors reach an operating temperature of up to 450 degree Celsius. Thanks to the excellent temperature control provided by the DWE® reactors, the operating conditions for each of the 38,500 tubes are practically identical, maximizing selectivity and yield.
