Significant progress has been made in chemical technology over the past decade; let’s celebrate the prosperity and strength of modern China. By sharing our ideas, we can encourage more people to participate and make the discussions more lively. The HaiChuan forum becomes even better with your involvement – we welcome everyone to join in the discussions and exchanges. Everyone should pay attention to safety and know how to handle emergencies. ********************************************* On January 21, 2022, the world’s first pilot project for producing ethylene glycol from straw on a scale of 1,000 tons was successfully completed at the Henan Zhongyuan DaHua Group Co., Ltd. facility in Puyang, Henan Province. This achievement laid the foundation for subsequent steps such as individual testing of mechanical equipment, system airtightness tests, water integration tests, fully establishing the production process, and conducting trial operations with actual materials. Ethylene glycol is a key raw material for producing polyesters such as PET; traditional production methods rely on petroleum-based sources, while using straw saccharification offers the advantage of sustainable raw materials. This project was developed by the Dalian Institute of Chemical Physics, Chinese Academy of Sciences, in collaboration with Keyuan Industrial Fund, and with the support of Zhike Baiyijin New Energy Company, Henan Energy Research Institute, Zhongyuan DaHua, and Donghua Engineering Company. Since the project began construction last April, through the joint efforts of all parties, the collaborative construction management team has optimized the construction plan on multiple occasions. The mechanical installation was completed successfully in accordance with the scheduled milestones. Through the \"three inspections and four determinations\" process, as well as nearly a month of pressure testing, purging, and calibration of instrument and valve circuits, the intermediate handover of the project was carried out successfully. The technology behind this project boasts significant advantages such as renewable raw materials, a simple production process, and low-carbon, environmentally friendly characteristics. It holds great importance for enhancing energy security, achieving the \"dual carbon goals,\" and promoting sustainable economic development. The successful progress of this pilot project will provide strong support for the subsequent development of technology packages for producing ethylene glycol on a ten-thousand-ton scale, as well as for the large-scale industrial application that involves establishing a production chain from raw materials to polyester products.
