On the one hand, overcapacity is seeking new growth points, on the other hand, environmental protection issues are imminent.
The "Time-Determined Treatment Plan for Air Pollution in Key Industries in the Yangtze River Delta Region" and the "Time-Determined Air Pollution Treatment Plan for Key Industries in the Pearl River Delta and Surrounding Areas" set strict requirements for both regions, and comprehensively transform the flat glass production line for desulfurization, denitrification and dust removal. Existing flat glass manufacturers have begun to implement the "Emission Standards for Air Pollutants for the Flat Glass Industry", but the reporter learned in recent interviews that some of them have not the regulations and still have excessive emissions.
At present, there are four main types of fuels used by glass companies in my country, namely natural gas, heavy oil, coal gas and petroleum coke. At present, most of the world uses natural gas as fuel, and part of it uses heavy oil. Most domestic enterprises use coal-based gas and petroleum coke. As we all know, the carbon emission intensity of petroleum coke and coal tar is about twice that of natural gas. In terms of input cost, the average investment in the desulfurization and dust removal system for each production line is 4 to 5 million yuan, and the annual operating cost is more than 2 million yuan. After increasing the denitration requirements, the investment and operating costs need to be more than doubled. Therefore, in order to reduce costs, some companies still choose to use highly polluting fuels such as petroleum coke and coal tar.
Smoggy weather has become the norm, and air pollution caused by industries such as steel, cement, electricity, and glass has attracted much attention. As the glass industry, although the total amount of flue gas emissions is not large, although my country's existing flat glass production process has been in line with international standards, there is still a large gap between product quality and energy consumption and the international level. As smog invades the city, people pay more attention to environmental protection. Behind more and more people begin to pay attention to environmental protection is the environmental problems brought about by the development of the glass industry, which has attracted the attention of the government.
In the course of history, those flat glass companies with small scale, poor quality, high renovation costs, and substandard energy consumption and environmental protection are bound to be eliminated. Environmental protection has become an inevitable trend in the glass industry. Only when companies in the industry follow the trend, gather wisdom and strength in the industry, and take a long-term, effective and stable environmental protection and energy-saving road suitable for companies, can they continue to develop healthily.
