From coal-fired power plants to non-electrical industries, atmospheric management is moving toward this path. Through the continuous advancement of governance in the past decade, the non-electrical industry has become the main area for further emission reduction under the limited development of coal-electricity emission reduction potential.
In the context of the near-saturation of the desulfurization and denitrification market in most coal-fired power plants, the non-electrical industry flue gas treatment is becoming an incremental market for the new round of blue sky defense.
At present, the further reduction of pollutants in the thermal power industry is constrained by the diminishing marginal space and the rising marginal cost. The main battlefield of air pollution control has been transferred to the non-electrical industry. The non-electrical field includes flue gas treatment of various industrial processes, involving cement, glass, petrochemical, and metallurgical.
“Especially, the emission of volatile organic compounds has not been effectively controlled. The main sources are petrochemical, chemical, industrial coating, packaging and printing industries,†said Liu Bingjiang, director of the Atmospheric Environment Management Department. Moreover, more than 400,000 large-scale coal-fired boilers have been distributed, and the amount of coal used for heating in large-scale urban villages, urban-rural areas and rural areas is even more alarming.
In order to achieve the governance goals of the Ten Elements and the “Thirteenth Five-Year Planâ€, promoting atmospheric governance in the non-electrical industry will be a relatively more cost-effective path. According to the “Development Report of Desulfurization and Denitrification Industry 2017â€, the non-electrical industry such as coking, steel and chemical industry accounted for 50% of the total consumption last year, and it has become the largest area for coal consumption.
This also means that in order to achieve air quality standards, the non-electrical industry needs to cut emissions by at least 50%. The CITIC Construction Investment Research Report pointed out that industrial enterprises' emission permits and sewage upgrades will expand the market space for emission reduction and control, especially for key industries in the non-electrical field.
In the 2018 government work report, it was clearly stated that it is necessary to raise the emission standards of the industry and achieve deadlines. According to publicly available information, there have been more than 20 national pollutant discharge standards revision sheets (draft for comments), so far, comprehensive increase in unorganized emission control for steel, building materials, nonferrous metals, thermal power, boilers, coking and other industrial sectors. Measure requirements.
The “13th Five-Year Plan†eco-environmental protection plan also takes the industrial pollution source into full-scale discharge as one of the 25 major national ecological environmental protection projects. "The Ministry of Environmental Protection will firmly grasp the main contradiction of air pollution control in non-electrical industries, and accelerate the control of pollution of industrial furnaces and coal-fired boilers and loose coal." Liu Bingjiang further pointed out.
However, due to factors such as non-electricity owners, environmental suppliers and other technologies, and the technology is far less mature than thermal power technology, the non-electrical industry smoke control is still in its infancy.
On the one hand, due to the wide range of non-electrical fields and the large number of sub-sectors, the production processes vary greatly among different industries, resulting in different pollution emission characteristics. On the other hand, due to the more complicated smoke components and working conditions, the ultra-low emission technology of non-electrical fields such as steel is more demanding and has not been applied. At the same time, the non-electrical field is more sensitive in terms of economy, and needs better technology to adapt to small units in the non-electrical industry to reduce input costs and meet transformation requirements.
How does the technical bottleneck break through the work of upgrading the standard? For the operation of environmental protection enterprises, the common view of the industry is that a third-party governance model can be adopted, which can solve the government’s benign development and environmental protection enterprises. Regulatory difficulties. With the gradual expansion of the market for flue gas treatment in non-electrical industries, market competition will become increasingly fierce, and the most competitive hotspot will be low-temperature denitration technology.
One of the companies that have really made innovations so far is to improve on the original basis, and the other is a process from 0 to 1. How to combine the characteristics of flue gas to achieve tailoring and improve the efficiency of industrial flue gas purification in non-electrical fields has become the only way for the current non-electrical industry to control the flue gas.
The introduction of multiple layers of design not only enhances the future development of air pollution prevention, but also brings opportunities for the development of non-electrical industry smoke control. The desulfurization and denitrification committee forecast shows that the market for atmospheric gas treatment in major non-electrical industries including steel, cement, flat glass and ceramics can reach as much as 300 billion yuan.
Specifically, the steel desulfurization market space is mainly reflected in the transformation field, and the promotion of professional third-party operational environment services in the future will be the general trend. Once the market breaks out, the installation requirements for monitoring and monitoring systems will also drive the environmental monitoring equipment and operation and maintenance fields into the fast lane.
