The reporter learned that the new projects, including the project of coking annual production of 1 million tons of coke by Taihua Coking, not only have the leading position in product quality and process technology in the same industry in China, but also realize closed circuit circulation, which is in line with high technology, high added value, and high Utilization and low consumption, low pollution requirements. Today, the new projects of Taihua Group all achieve energy conservation and emission reduction, and they have passed the environmental protection barrier from the source. According to incomplete statistics, these new projects can save about 120 million yuan in funds each year through energy conservation and emission reduction.
In recent years, Taihua Group invested nearly 800 million yuan in technological transformation and implemented six key projects, of which more than 200 million yuan was directly used for environmental protection and energy conservation and emission reduction.
The annual 200,000-ton benzene hydrogenation project of Taihua Baoyuan Co., Ltd. will concentrate the crude benzene in the coking process in Shanxi Province and its neighboring provinces for deep processing and turn into pure benzene, forming an alternative product to petroleum and coal chemical industry. This is a state-of-the-art modern production device with the largest capacity, advanced technology, and outstanding scale advantages. This project has fully achieved the goal of energy saving and emission reduction of closed circuit circulation, and the energy consumption per unit product has reached the national leading level in the industry.
Taihua Coking Plant's new annual production of 1 million tons of coke projects, tons of coke consumption of clean coal, steam consumption reached the national advanced level in the same industry. An annual output of 200,000 tons of PVC project built in Taihua Chalkali Industrial Park will realize zero discharge of waste water; the new annual production capacity of 60,000 tons of ion-exchange membrane caustic soda project will save more than 50 million yuan in steam value compared to diaphragm caustic soda. The Taihua Real Estate centralized heating device invested and built with advanced domestic water source heat pump technology will focus on the use of waste water and heat, saving more than 6,000 tons of fresh water annually.
At present, these projects can save more than 50 million yuan worth of raw material consumption annually, save water, electricity, gas and Other energy value of more than 7,000 million, becoming an "extraction point" for enterprises to tap potential.
On November 9, the reporter saw at Taihua Industrial Park that the largest coking crude benzene hydrotreating project in the country, Taihua Baoyuan, had an annual output of 200,000 tons of benzene hydrogenation. The plant was closed, and the entire process achieved clean production.
