Transformation of coal chemical industry under the ten water policies

wallpapers Industry 2020-12-09

on April 16, 2015, the State Council officially issued the water pollution prevention and control action plan, referred to as the "water ten articles". Coal chemical industry consumes a large amount of water, and sewage treatment is very important. The proposal of "ten water regulations" has posed an unprecedented challenge to the industry. Environmental protection transformation of coal chemical industry has become the focus of attention. Huang Anxin, technical director of

and

, said in an interview with energy magazine that the impact of the new policy is relatively large, which mainly refers to the pollution control cost brought by environmental protection problems to coal chemical enterprises.

Hou Xiangsheng, executive vice president of

New Austrian Energy Research Institute, told energy magazine that Lurgi furnace, the main type of coal to gas furnace, is now widely criticized. This is because Lurgi furnace will produce a lot of COD in the production process. In addition, heavy metals will be produced in the coal chemical production process, which will pollute the local land. The wastewater discharged from coal chemical industry will make the water salinity too high, making the water unable to be reused Livestock drinking can not be used as agricultural water.

and

now, more stringent policies have brought pressure on the operating costs of coal chemical enterprises. The decline of oil price and the depression of coal industry have already exerted pressure on coal chemical industry. Now, the new pressure comes from environmental protection. Coal chemical technology is relatively mature, simple process, its production cost is not high, but its water pollution treatment technology cost is high. Qi Yonghong, vice president of Yanchang Petrochemical Design Institute, told energy magazine that the company's Yulin kerosene gas comprehensive utilization wastewater nearly zero discharge project investment reached nearly 300 million yuan.

and

and "ten water regulations" stipulate that by 2020, the total water consumption in China will be controlled at 670 billion cubic meters, and the problem of water resources is very urgent. During a survey in Inner Mongolia in March this year, Nur Baikeli, director general of the state energy administration, put forward: "for coal chemical projects without road strips, the support of water resources should be fully considered."

and

from the perspective of environmental governance, the "water ten" has indeed played a restrictive role in water saving and pollution control of coal chemical industry. Although most experts think that the water 10 is more like a shackle of the industry, many people in the industry have expressed their affirmation. "The ten water regulations have curbed the coal chemical industry, but there is nothing wrong with this containment. Without technology, don't go to the coal chemical project in Malaysia, "says Hou Xiangsheng.

and

with the implementation of the "ten water policies", the coal chemical industry has to face torture.

Hou Xiangsheng said that enterprises are the main body of pollution, who pollutes and who governs is the environmental responsibility that enterprises must bear. At present, many coal chemical enterprises have adopted different technical routes to control pollution. After the exposure of the sewage illegally discharged from Shenhua coal to oil project by Greenpeace, Shenhua Group adopted the open pit and mine drainage water around the project as the phased alternative water source, and built the corresponding water purification plant, which basically achieved zero discharge at present. New Austria also applied supercritical technology to its projects, and the effect was obvious.

and

, but in the depressed period of the industry, due to the high cost of pollution control, the enthusiasm of enterprises is not high, and the enthusiasm of investors will also decline. To deal with the contradiction between economic growth and coal chemical pollution, economic leverage is needed to leverage the transformation of coal chemical industry, which is generally considered by Hou Xiangsheng and most practitioners as an effective way. In China, coal pollution has been mainly controlled by administrative means. However, the effect of this method has been limited. In January this year, the most stringent new environmental protection law was issued, giving environmental protection departments the power to shut down polluting enterprises. However, some enterprises have repeatedly prohibited the phenomenon of using regulatory loopholes to secretly discharge pollutants. Besides administrative means, the more effective means of

and

is economic leverage. Hou Xiangsheng believes that first of all, we should macro-control water prices. The price of industrial water in China is too cheap, and the price of industrial water in most areas is about 6 yuan / ton, which leads to the tendency of enterprises to apply for more water indicators instead of water pollution control. If the water price can be adjusted to about 20 yuan / ton, enterprises will have greater willingness to invest in pollution control, rather than apply for water quota randomly. Secondly, the pricing mechanism of water resources should be changed. The stepped water price system implemented in some areas of China should also be used to cover the areas covered by coal chemical industry. While increasing the price of industrial water, the price of residential water is relatively reduced, and the more used, the higher the price. However, the current situation is that in many coal chemical rich areas, this ladder price is still blank. In addition, the development of coal chemical industry should be adapted to local conditions. The so-called measures to local conditions refers to the comprehensive consideration of water resources, traffic conditions and environmental capacity on the basis of coal resources. Hou Xiangsheng of

and

said that the contrast between new Austria's coal chemical projects in Daqi and Tengzhou is the best case. A ton of coal in Daqi is about 400 yuan / ton, while Tengzhou needs to transport coal from other places, so the cost of coal should reach 700 yuan / ton, and the profit of Daqi project is far more than that of Tengzhou.

and

coal chemical industry itself is a high water consumption industry, but many coal chemical projects are often located in Inner Mongolia, Shaanxi, Ningxia and other areas where water resources are relatively scarce. Coal resources and water resources are in a reverse distribution state, and water energy problems are very prominent. In Northwest China, the development of coal chemical industry is restricted by water, which is a problem of contradiction and unity between economy and environment. Dealing with the relationship between the two is a healthy way for the development of coal chemical industry.
