2012 Wanhua won the 2nd Prize of National Technological Invention Award

On January 17, 2012, the project named new technology of strengthening rotating packed bed reactor accomplished through the cooperation between Yantai Wanhua Polyurethane Co., Ltd. (predecessor of Wanhua Chemical Group Co., Ltd.) and Beijing University of Chemical Technology won the 2nd Prize of National Technological Invention Award of 2012. This project invents a series of rotating packed bed reactors or separators with novel structure that can be applied in the separation of substances in different reaction systems and in low-density and high-viscosity systems, proposes a new method of strengthening and adjusting rotating packed bed reactor during the rapid liquid phase reaction process restricted by micro mixing and transferring, the new technology of strengthening and condensation of rotating packed bed is original in the world and successfully applied in multiple sets of MDI equipment of Wanhua with remarkable energy-saving and consumption-reducing as well as capacity-expanding and yield-increasing effect. This reward is the fifth national scientific and technological award won by Yantai Wanhua after winning the 1st Prize of National Progress Awards in Scientific & Technological and the 2nd Prize of Progress Awards in National Scientific & Technological. Winning a series of national awards fully demonstrates the technological R&D capacity and scientific and technological innovation capacity of Yantai Wanhua, meanwhile, it shows the comprehensive competitive strength and industry leader position of Wanhua in the MDI manufacturing field.
