Re-evaluation of certain aspects of Qixiang Tengda’s 200,000-ton isononanol project

Thread Content

Recently, a global research team in the chemical industry learned from relevant sources that the environmental impact assessment for Zibo Qixiang Tengda Chemical Co., Ltd.’s 200,000 tons per year isononanol production project (the butylene separation unit in its first phase) has been made public for comment. The deadline for submitting comments is from January 29, 2026, to February 11, 2026 – a total of 10 working days. At present, Qixiang Tengda has two manufacturing sites in the Zibo area: one is located in the eastern part of the Qilu Chemical Industry Zone (the old plant), and the other is in the southwest corner of the same zone (the new plant). The distance between the two plants is approximately 6 kilometers. The proposed project is located in the new factory area. Zibo Qixiang Tengda Chemical Co., Ltd. plans to invest 1,798.69 million yuan in the construction of a new plant facility to produce 200,000 tons per year of isononanol. The construction scope includes a butylene production unit with an output of 350,000 tons per year, an octene production unit with an output of 180,000 tons per year, an isononanol production unit with an output of 200,000 tons per year, a syngas production unit with an output of 88 million Nm3 per year, as well as facilities for catalyst preparation, recovery, and evaluation. The project has obtained the approval certificate for construction projects in Shandong Province. The 200,000 tons per year isononanol project is a key project in Zibo City. To promote the construction of this project and accelerate its implementation, the enterprise has decided to conduct phased evaluations of the project according to the progress achieved in the design of the facilities. In 2021, an evaluation was conducted on the 350,000 tons per year butylene plant, and a report titled \"Environmental Impact Assessment Report for Zibo Qixiang Tengda Chemical Co., Ltd.’s 200,000 tons per year isononanol project (Phase I: Butylene separation unit)\」was commissioned for preparation. The facility has now been constructed and is currently in the debugging phase.
