The chemical industry in various countries actively cools the earth

A report by Reuters on January 3 drew attention: British scientists predict that 2008 will be the coolest year since 2000, but it is still ranked as the hottest 10 years since 1850, global warming is far Not finished. As the global response to climate change surges higher than a wave, many well-known chemical multinational companies are stepping up their near-and-long-term strategies and taking active actions.
Set goals and actively respond In November last year, Bayer launched the "Bayer Climate Plan." Including, between 2008 and 2010, the company will invest 1 billion euros in research and development projects to solve global warming issues. When choosing a new project that exceeds $10 million, the company will introduce a new funding expenditure selection process, "Climate Change Criteria." In addition, Bayer MaterialScience has committed to reducing its greenhouse gas emissions to 75% by 2005 by 2020. Bayer HealthCare and Bayer AG will say that their emissions will fall to 95% and 85% of current levels by 2020 respectively.
In December last year, Dow Chemical joined the climate team to promote the implementation of pragmatic climate change policies and demonstrated that the company can still make profits while cutting emissions. The climate team was established in 2004 and is dedicated to promoting business and government solutions to climate change. Dow Chemical stated that it will use its expertise in chemicals and innovation to solve climate change issues around the world and propose to stop the growth of its absolute greenhouse gas emissions by 2025 and by 2050, at least half of the energy used will come from Renewable energy or carbon-free power generation.
Playing the role of technical support Whether in the research center of a company or in a laboratory of a university, the role of the chemical industry in playing a role of technical support in cooling the earth can be seen everywhere.
Last year, BP launched the "carbon emission calculator" and hoped to inspire everyone in an intuitive, fresh, and easy-to-use manner to contribute to the suppression of climate change. The “BP Carbon Emissions Calculator” can calculate the CO2 emissions from home, travel, and shopping in accordance with the family housing structure, energy consumption, and environmental habits. In addition, with this interactive multimedia tool, BP also provides experiential tips for reducing CO2 emissions.
Researchers at the membrane research group of the Norwegian University of Science and Technology in Trondheim have recently developed a new type of nanostructured plastic film that can separate CO2 from power plant exhaust gas at a low cost. By using this membrane, the concentration of CO2 gas in the feed gas mixture can be increased, thereby reducing the cost of separation. The team said that the new membrane technology will be tested at four large-scale power stations in Europe in the next five years.
Decomposition of stable CO2 molecules is very difficult, but researchers at the Sandia National Laboratories in New Mexico state believe that its designed high-efficiency chemical reactions are sufficient to make it an effective way to produce liquid fuels from CO2. The research team uses a centralized solar-driven chemical reaction to decompose CO2 to produce carbon monoxide and decompose water molecules to obtain hydrogen. These two products then synthesize liquid hydrocarbon fuel, and the test device will be available this spring. Sandia’s Fuel and Energy Conversion Department stated that their ultimate goal was to develop a series of solar reactors, each capable of collecting about 22 kilograms of CO2 and 18 kilograms of water per day, producing 2.5 gallons of gasoline.
The cost of capturing CO2 from the atmosphere to reduce the emission of greenhouse gases is extremely high. The current operational difficulties lie not in technical feasibility but in how to reduce energy consumption and other costs. Not long ago, scientists from Columbia University in New York, United States, have designed a technical solution that can effectively reduce the energy consumption of this process by adjusting experimental devices. They are said to conduct field experiments in May this year.
Gan is a pioneer in practice At present, international experts believe that the capture of CO2 and its geological burial are effective means to maintain the global environment and resist environmental changes. Last year, global chemical companies were extremely active in capturing and storing CO2.
In early February of last year, Air Liquide and Total announced a technical cooperation in the capture and storage of CO2, providing a new oxygen combustion technology for the first CO2 capture and storage unit in the French Lacq industrial site in southwestern France. Total will inject more than 150,000 tons of CO2 into abandoned natural gas wells 4,500 meters deep near Lacq in more than two years. The first CO2 injection will take place in November this year. At the same time, Air Liquide also participated in several other CO2 storage projects, particularly in Poland, the United States, and Canada.
In May last year, BP and Rio Tinto Mining Group announced the establishment of a hydrogen energy joint venture to expand the global decarbonization energy project. The project converts fossil fuel feedstocks such as coal, petroleum coke or natural gas into gaseous H2 and CO2, and captures CO2 deep in the rock below the surface.
Powerspan USA has developed the ECO2 capture process that uses aqueous ammonia solution to capture CO2 from power plant flue gas. This is the result of a joint study between the company and the U.S. Department of Energy’s National Energy Technology Laboratory. BP Alternative Energy and Powerspan are developing and verifying this technology and will use it for the commercialization of coal-fired power plants.
In addition, the use of captured CO2 to produce chemical products has become a good way to kill two birds with one stone. At the end of last year, Mitsubishi Heavy Industries of Japan (MHI) announced that it has transferred its flue gas CO2 recovery technology to Gulf Chemical Industry Company (GPIC), a manufacturer of fertilizers and petrochemicals in Bahrain. GPIC will use this technology to recover CO2 from flue gas from its existing petrochemical plant and use captured CO2 to increase urea and methanol production. The recovery facility is said to capture 450 tons of CO2 per day and is scheduled to be completed by January 2010.
