The frames of the cooling towers for the fifth and seventh circulating water units in the second-phase coal chemical project of China Coal Shaanxi have successfully reached their completion stage. Recently, the frames of the cooling towers for the fifth and seventh circulating water units of this project, which are under construction by Erhua Jian, were completed simultaneously, and the achievement of these two milestones marks a new phase in the project’s development. This project is the first large-scale coal chemical project approved by the Ministry of Ecology and Environment since the implementation of the \"dual carbon\" strategic goals. It also serves as a pilot project for evaluating carbon emissions in the coal chemical industry. Once operational, it will help to promote the optimization and upgrading of the industrial structure, and during the construction phase it could create tens of thousands of jobs.
