Originally published as Nature: Seven world-changing chemical separation technologies David Sholl, one of the authors of the commentary and dean of the School of Chemical and Biomolecular Engineering at Georgia Institute of Technology, said, "What we want to emphasize is that there is a lot of energy used in chemical separation in the world, but there are some areas where we need to strengthen the research and development of chemical separation processes." It is hopeful to achieve a major breakthrough in energy conservation. Although most people have no idea about these processes, the development of new technologies in these separation processes is of great significance from the point of view of saving energy and protecting the environment. Taking the United States as an example,rotovap distillation, if non-thermal separation technology can replace traditional separation technology, the annual energy expenditure for petroleum industry, chemical industry and paper industry can be reduced by $4 billion, and the annual carbon dioxide emissions are expected to be reduced by 100 million tons. "Chemical separation consumes about half of the energy consumed by industry in the United States," said Ryan Lively, an assistant professor in the School of Chemical and Biomolecular Engineering at Georgia Institute of Technology and the second author of the article. "Developing alternative processes that do not consume heat can greatly improve the efficiency of separation processes by 80% on the basis of existing technologies." Expand the full text Here are their picks for "seven chemical separation processes that will affect the world": The separation of hydrocarbons from crude oil. Hydrocarbons in crude oil are the main raw materials for the production of fuels,wiped film evaporator, plastics and polymers, and play a vital role in the world economy. According to the article, refineries around the world process a total of about 90 million barrels of crude oil per day, mostly using atmospheric distillation, which consumes about 230000 megawatts of energy per year, equivalent to the energy consumption of the United Kingdom in 2014. In the process of distillation, the oil is first heated, and then, due to the different boiling points of different compounds, thin film distillation ,wiped film distillation, their volatilization rates are also different in the heating process, which can be used to collect different compounds.  However, regardless of whether membrane or distillation technology is used, the process is both energy and capital intensive. The development of high-yield,wiped film distillation, anti-fouling films is expected to reduce their cost. At the end of the article, Sholl and Lively summarize four steps for researchers and policy makers to promote the application of non-thermal separation technology: Return to Sohu to see more In the process of research, scholars should consider the actual chemical mixture and the actual engineering conditions; Evaluate the economics and sustainability of any separation technology; Consider the scale of the technology when it is actually applied in industry; Enhance the training of chemical engineers and chemists to improve their understanding of separation techniques without distillation Responsible Editor:. toptiontech.com
