At present,a new international trade competition pattern based on energy conservation,environmental protection,green and low carbon has been formed.On March 28,at the 2014 Green Chemical Industry Forum jointly organized by the China Petroleum and Chemical Industry Federation,the Macao Trade and Investment Promotion Agency,and the Macao Environmental Protection Agency,Zhao Jungui,the vice chairman of the Petrochemical Federation,said that the petroleum and chemical industry is a clean For industries with large production potential and strong demand,my country has raised the construction of ecological civilization to an unprecedented strategic height,and the entire industry will face greater pressure on the ecological environment and institutional constraints.How should my country speed up to catch up with the international advanced in this green chemical industry competition?Which environmental protection technologies need to be strengthened urgently?What technical means are needed?The reporter also found part of the answer from the meeting.
The technical support system needs to be improved urgently
According to Zhou Xianhui,Deputy Secretary-General of the Petrochemical Federation,in recent years,my country’s petroleum and chemical industry has strengthened the basic work of cleaner production,the standard system has been initially established,the pace of technology research and development and promotion has accelerated,and the promotion of energy saving and emission reduction in the industry has achieved obvious results,and a number of typical Demonstration enterprise.To promote cleaner production in the future,we will adhere to the principles of combining technological research with popularization and application,combining key breakthroughs with comprehensive promotion,and combining policy guidance with market mechanisms.
She proposed that the focus of promoting cleaner production in the petroleum and chemical industries is to accelerate the development and industrialization of key common technologies,accelerate the promotion of advanced and applicable cleaner production technologies,and implement cleaner production to promote the emission of key pollutants.The ammonia-nitrogen industry should speed up technological transformation to effectively complete the national ammonia nitrogen emission reduction target;the soda ash industry should speed up the promotion of technologies such as the Hou-soda cleaning process,new-type transformation gas soda production,and non-cold carbonization;the toxic and hazardous raw material industry should do a good job in raw material substitution and environmentally friendly The industry involved in bulk industrial solid waste should accelerate the promotion of comprehensive resource utilization technology;the industry involving toxic and hazardous materials should do a good job in the substitution of raw materials and the production of environmentally friendly products;the industry involving bulk industrial solid waste should accelerate the promotion of comprehensive resource utilization technologies.
At the same time,a clean production technology support system,technology promotion platform,and review and training system should also be established to give full play to the leading role of advanced enterprises;organize the development of"green chemical park"cultivation work to give full play to the leading role of demonstration enterprises.Intensify policy research;promote financial funds to increase support for cleaner production,improve cleaner production policy mechanisms,and improve cleaner production review and evaluation.
The key technology development direction is clear
Petrochemical Federation Deputy Secretary-General Hu Qianlin pointed out that the petroleum and chemical industry has entered a critical period of transformation and upgrading,and its process will rely on the support of environmental protection technology.In the future,the development of environmental protection technology in my country is mainly reflected in three aspects:consider environmental protection from the whole life cycle,that is,product green technology;reduce emissions from the source,that is,clean production technology;control pollution from the end,that is,"three wastes"treatment and resources化技术。Technology.
In terms of product green technology,the focus is on the development of clean oil technologies,such as ionic liquid catalyzed by carbon four in liquefied petroleum gas to produce alkylated gasoline,diesel ultra-deep hydrodesulfurization,diesel hydro-upgrading for the production of clean oil,and biodiesel Production and methanol production of polymethoxy dimethyl ether;development of water-based,solidified,green and environmentally friendly pesticide preparation production technology.At the same time,we should vigorously develop environment-friendly fertilizer production technology,environment-friendly fine chemical production technology,ultra-low formaldehyde release urea-formaldehyde resin technology,green tire technology,bio-based polymer materials,etc.
In terms of cleaner production technology,the focus is on the development of clean production technology for oil refining;development of cleaner production technology for pesticides,such as the new clean production process of paraquat cyanamide and the new production process of acetochlor methylene;the development of clean production technology for dyes;the development of papermaking chemistry Product production technology,such as continuous automatic production technology of modified starch for papermaking;development of green tire processing technology,such as low-temperature rubber mixing technology;development of new technology for clean production of titanium dioxide by"sulfur-phosphorus-titanium"co-production method;development of mercury-free catalyst PVC production Technology;Develop complete production technology of direct oxidation propylene oxide.
In terms of"three wastes"treatment and recycling economy technologies,the focus is on the development of wastewater treatment and resource recovery technologies,such as oilfield produced water treatment technology,oil refinery wastewater treatment technology,polyurethane waste liquid treatment technology,advanced treatment and resource recovery technology of glyphosate mother liquor,Comprehensive treatment technology for printing and dyeing wastewater,treatment technology for high-concentration ammonia nitrogen wastewater,by-product hydrogen chloride to produce chlorine technology;development of waste gas treatment and recycling technology,such as high-gravity field recovery tail gas sulfur dioxide technology,coke oven tail gas recycling technology,calcium carbide tail gas production Alcohol technology;development of waste solid treatment and resource recovery technology,such as phosphogypsum resource recovery technology.
Quantitative analysis supports green transformation
David Hathaway,the global vice president of ICF International Consulting,believes that the challenges faced by petrochemical companies during the economic transition are:rising raw material and energy prices lead to high operating costs,and the"Twelfth Five-Year Plan"has formulated energy-saving and low-carbon companies for thousands of companies.Task indicators,relevant arrangements for the guidance on energy conservation and emission reduction in the chemical industry,the requirements of China’s air pollution prevention and control action plan,and the pilot carbon trading system.However,if sustainable development can be integrated into the core business strategy,outstanding companies will win with a green strategy.
He said that business managers need to think about where the green transformation starts,how to quantify and analyze green sustainable development improvement measures,what measures should be implemented,how to arrange the implementation sequence,how to choose technology providers,and how to participate in the market mechanism(Carbon trading),how to reduce the cost of compliance and how to create value?Simply put,when companies implement green development,they should know when,how,and where to start.
In Hathaway’s view,to improve green development performance,companies need to clearly and comprehensively evaluate and select appropriate energy efficiency action methodology,a clear energy efficiency implementation roadmap,a clear implementation sequence for selected energy efficiency measures,and based on energy efficiency.And environmental impact investment strategies.If these can be achieved,we can ensure that energy-saving and emission-reduction goals are achieved based on reliable analysis and planning;strategically select the most promising and cost-effective technologies/measures and implement them in the appropriate order;the savings can be Use scientific estimates to support financing;at the same time make wise investments as needed.
