Thread Content

On April 10, the Zibo Ecology and Environment Bureau intends to make a decision regarding the approval of the environmental impact assessment document for Shandong Qixin Gas Co., Ltd.’s hexafluorobutadiene expansion project, and will make this decision public. The details of the project are as follows: Location of construction: North of Planning Hengsi Road and east of Tianyi Road, within the Gaoqing Chemical Industry Park, Gaocheng Town, Gaoqing County, Zibo City, Shandong Province. This is an expansion project. The main construction elements of this project include: building upon the existing production facility area, adding 4 addition reactors (including preheaters), 2 dehalogenation reactors, 2 dealkylation units, 2 dichlorohexafluorobutylene metering tanks, 1 dichlorohexafluorobutylene distillation column, 3 hexafluorobutadiene distillation columns, 1 diaphragm compressor, 1 tank for hexafluorobutadiene semi-finished products, 1 condenser for that tank, and 1 set of vacuum spiral dryers. At the same time, the 4 addition reactors (2 in use and 2 as spares) within the existing hexafluorobutadiene production facility area were upgraded to be put into full operation later. Add 2 air compressors, 1 set of refrigeration units, an exhaust gas treatment system, temporary storage areas for raw materials, auxiliary materials, and products, initial rainwater tanks and accident water tanks, a hazardous waste storage area; the office area will be constructed using the existing infrastructure ； The fire water tank, pure water production system, nitrogen generation system, and sewage treatment station are located at NanDa Optoelectronics (Zibo) Co., Ltd. After the expansion, the production capacity of hexafluorobutadiene increased from 30 t/a to 200 t/a ； The production capacity of 1,2-dichlorohexafluorocyclobutane has been increased from 50 t/a to 330 t/a.
