Industry calls for a positive image of modern coal chemical industry

wallpapers Industry 2020-12-09

in China's modern coal chemical industry has been criticized for its high water consumption and large discharge. Recently, the new environmental protection law and the "ten water regulations" have pushed it to the top of the storm. On May 20, at the 2015 Forum on environmental protection technology application and innovation of coal chemical industry held by coal chemical industry special committee of China Petroleum and Chemical Industry Federation in Beijing, the industry called on coal chemical enterprises to shoulder social responsibility, change passive to active in environmental protection of "three wastes" treatment, change pressure into power, and establish a positive image of the industry by adopting new environmental protection technologies. Hu Qianlin, Deputy Secretary General of the China Petrochemical Federation and Secretary General of the coal chemical industry special committee, said that at present, the disposal and discharge of solid waste and waste gas from coal chemical industry can be basically controlled, and it is difficult to treat wastewater, especially high concentration refractory organic wastewater. For example, the waste water of fixed bed gasification and low rank coal pyrolysis process is complex, containing tar, phenol, polyphenol, etc., which is difficult to be treated by general biochemical process. In addition, it is difficult to treat the saline wastewater, so it is difficult to achieve near zero discharge in the area where there is a lack of receiving conditions. In recent years, many coal chemical enterprises have made great efforts for sewage treatment, but the actual effect is not ideal, the practical technology is still in the exploratory stage, and the cost is high.

and

coal is the fossil fuel with the highest carbon content. In 2015, the CO2 emission of coal chemical industry was about 470 million tons, which brought pressure on China's carbon emission reduction. The national unified carbon emission trading market is planned to be put into trial operation in 2016, and the carbon tax will also be accelerated, which will inevitably increase the investment cost of coal chemical projects and affect their comprehensive competitiveness. Once the carbon tax exceeds 100 yuan / ton, coal chemical projects will be difficult to bear.

and

Hu Qianlin stressed that to solve these problems, we must implement the most stringent environmental protection standards, seriously implement the environmental impact assessment system, and ensure that environmental protection facilities and the main project are designed, constructed and put into operation at the same time. Especially in wastewater discharge, it is necessary to strictly implement the red line management requirements of water function area. The coal chemical project should meet the following conditions: all process wastewater is recycled, the circulating water system sewage is not discharged to the outside of the plant, and there are perfect underground water seepage prevention measures. Zhou Zhuye, vice president of

and

, put forward three suggestions on how to promote green, low-carbon and circular development of modern coal chemical industry: first, strictly implement "three Simultaneities" in the construction and operation of coal chemical projects. We will strictly implement the action plan for the prevention and control of air pollution and strengthen cleaner production and pollution control. General industrial solid wastes such as gasification ash and boiler ash are comprehensively utilized to the maximum extent. The waste residue that can not be used such as miscellaneous salt after high salt water concentration is sent to the slag yard for storage or landfill. Hazardous wastes such as waste catalyst shall be recycled and treated by supporting special facilities.

and

are to actively research and develop "three wastes" treatment and energy saving and water-saving technologies, carry out efficient and reasonable zero emission or near zero emission technologies, and improve the energy-saving, water-saving and environmental protection level of the industry. For example, air cooling water-saving, low-level heat utilization, high-efficiency power saving, high-efficiency dust removal, sulfur recovery, denitration, phenol ammonia recovery, wastewater pulping, activated carbon adsorption and other technologies.

and

are to strengthen the development of CO2 capture, application and storage technology, carry out CO2 oil displacement, microalgae absorption, geological storage and other experimental work, and encourage areas and coal chemical enterprises with conditions to develop CO2 recovery and utilization technologies, such as carbon sink, oil displacement, gas displacement, CO2 chemical production, etc. At the

and

meetings, many representatives of coal chemical enterprises and relevant experts put forward suggestions and opinions on how to establish a new environmental image of modern coal chemical industry.
