In 2014, our company undertook the first section of the equipment pipeline chemical cleaning project for the Yantai Wanhua relocation integration project and the PO/AE integration project. We successfully completed all chemical cleaning work for the MDI device, public works device, epoxy propane device, and pipeline from the storage and transportation tank area to the acrylic acid device.
