Recently, the environmental impact report for Henan Zhongyuan Dahuahua Group Co., Ltd.’s kiloton-scale pilot project aimed at producing ethylene glycol from straw was made public prior to its submission for approval. Henan Zhongyuan Dahuahua Group Co., Ltd. intends to fully master the technology related to biomass ethylene glycol by actively participating in the design and development of pilot-scale projects for this substance, thereby gaining practical engineering experience and laying a solid foundation for the industrial scale-up of this technology within the company. Against this backdrop, the company plans to invest in the construction of a pilot-scale project for producing ethylene glycol from straw sugar on a scale of 1,000 tons. By leveraging the new biomass-based route to ethylene glycol with independent intellectual property rights, developed by Zhongke Baiyijin (Zhengzhou) New Energy Technology Co., Ltd. – a company formed jointly by the Dalian Institute of Chemical Physics of the Chinese Academy of Sciences and Henan Keyuan Industrial Investment Fund Partnership – Donghua Engineering Technology Co., Ltd., together with Zhongke Baiyijin and Zhongyuan Da Hua, will carry out the design for scaling up this process on a pilot scale. Once completed, this pilot plant will be able to produce 746.8 t/a of ethylene glycol and 194.4 t/a of propylene glycol. The main raw materials for the project are straw sugar aqueous solution and H2; ethylene glycol is produced through ethylene glycol synthesis and ethylene glycol distillation reactions. Project H2 comes from the existing facilities of Zhongyuan Dahuahua Company; it does not require storage and is transported directly through pipelines. The project is located at the southwest corner of the intersection of Shihua Road and Pushui Road in the Puyang Economic and Technological Industrial Cluster (including the Puyang Economic Development Zone), within the existing premises of Zhongyuan Dahuahua Company. The total investment amount is 20.98 million yuan, and the project code is 2020-410972-26-03-030443. On the morning of April 9, 2021, the groundbreaking ceremony for Zhongyuan Dahuahua’s pilot project for producing ethylene glycol from straw on a scale of 1,000 tons was successfully held; this project was carried out by the Ninth Engineering Company of 11th Chemical Construction Corporation.
