Wang Wentang told reporters that the development of a low-carbon economy has brought a golden opportunity to the low-carbon chemical industry. The so-called low-carbon chemicals, that is, various chemicals produced by using greenhouse gases as raw materials, and chemicals whose production processes can significantly reduce greenhouse gas emissions. China is currently the world’s largest emitter of greenhouse gases. Adequate sources of raw materials and huge market demand will enable China to become a major country with low carbon chemicals.
According to a survey conducted by the China Chemical Industry Energy Technology Association, as of now, China has successfully developed a number of carbon dioxide emission reduction technologies and low-carbon chemical production technologies, and has already invested in industrial production and applications. For example, Nanhua Research Institute has developed a series of practical patented technologies such as low partial pressure carbon dioxide recovery technologies, NHD desulfurization and decarbonization technologies, and HS desulfurization and decarbonization technologies. Low-pressure partial pressure carbon dioxide recovery technologies such as flue gas have been successfully applied. In Chitianhua, Sichuan Vinylon factory and other companies. The decarbonization plant of Huaneng Shanghai Shidongkou Second Power Plant adopting this technology has been successfully put into operation in December 2009, and its carbon capture capacity has reached 100,000 tons/year, which indicates that China's coal-fired carbon dioxide capture technology and scale have achieved a revolutionary The leap has reached the international advanced level. The carbon dioxide it captures can be used in the production of urea, methanol, synthesis gas, acetic acid, food and other fields.
The Yangzi Petrochemical Company's ethylene glycol plant produces an annual output of 240,000 tons of ethylene oxide equivalent. In the hydration reaction of the plant, it discharges 8 tons of carbon dioxide gas to the atmosphere every hour. The company uses carbon dioxide as an auxiliary raw material for the carbon monoxide plant. In July this year, it succeeded in realizing the CO2 emissions from all recycled ethylene glycol plants. The project also successfully applied for the National Greenhouse Gas Emissions Award Fund.
The production of biodegradable plastics from carbon dioxide is one of the highlights of the development of low-carbon chemicals in recent years. The aliphatic polycarbonate copolymerized with carbon dioxide and propylene oxide has biodegradability, not only solves the white pollution caused by the current degradation of the plastic products, but also reduces the emission of carbon dioxide. The modern carbon dioxide-based plastic production line of China Shipping Chemical Co., Ltd. has been successfully put into operation in 2009, providing a good demonstration of the industrialization of carbon dioxide-based plastics.
In addition, there are many companies in China that use carbon dioxide to produce dimethyl carbonate, which can consume 0.49 tons of carbon dioxide per metric ton of dimethyl carbonate produced. With the gradual development of the downstream market of dimethyl carbonate, the production of dimethyl carbonate with carbon dioxide will become one of the important ways to reduce carbon emissions.
According to Wang Wentang's introduction, converter gas to methanol, carbon dioxide directly as a fertilizer for green plants, carbon dioxide flooding (exploitation of oil), coalbed methane (gas) to syngas, methanol, hydrogen and other technologies, can also significantly reduce greenhouse gas emissions .
“At present, low-carbon chemical technology development has attracted high attention in institutions of higher learning and scientific research institutions, and the technical input has been increasing substantially. It is foreseeable that with the end of November, Mexico’s Cancun Climate Change Conference and China’s 12th Five-Year Plan. 'The official introduction of low-carbon indicators, low-carbon chemicals will become a new hot spot for technology development, but also will become a new economic growth point.' Wang Wentang said.
The development of a low-carbon economy is a drag, burden, and barrier for slow-response companies because these companies fear that carbon reductions will require investment and carbon taxes, and that products entering the international market will have a low-carbon threshold. However, in the eyes of Wang Wentang, low-carbon economy is more of an opportunity for chemical companies. He believes that the development of low-carbon chemicals will bring multiple benefits to chemical companies, including product sales revenue, the transfer of carbon indicators such as CDM, or the additional benefits of carbon tax credits, low-carbon policy incentives at all levels of government, and the completion of carbon reductions. Scheduled tasks, etc. “Now is the best time for chemical companies to develop a low-carbon chemical market. Whoever moves fast will take the initiative in a low-carbon economy,†said Wang Wentang.
The rise of low-carbon chemical industry is at the right time
The UN Climate Change Conference held in Copenhagen at the end of 2009 pushed the low-carbon economy to the front desk, reducing the consumption of high-carbon energy such as oil and coal as much as possible, thereby reducing greenhouse gas emissions and curbing global warming. The new UN Climate Change Conference to be held in Cancun, Mexico, at the end of November this year will continue to deepen the theme of economic and social development and protection of the ecological environment, and further clarify carbon emission reduction targets. Wang Wentang, secretary-general of the China Chemical Industry Energy Technology Association, said that the introduction of low-carbon economy and carbon emission reduction targets has brought considerable pressure on the development of high-energy-consuming oil and chemical industries, but it has also created unprecedented opportunities.
