Eaton develops economic family refueling station for natural gas vehicles
Eaton recently announced that it will develop an economical home refueling station for natural gas vehicles, utilizing the family’s existing natural gas sources and innovative compressor technology to safely and effectively provide vehicles with alternative fuels. The project's funding was partially funded by $3.4 million in funding from the US Department of Energy's Advanced Research Projects Agency Energy Agency (ARPA-E). The goal is to develop prototypes for gas stations that retail at one-tenth the cost of currently available systems. The development was led by a team of Eaton Innovation Centers in Southfield, Milwaukee, Michigan and an advanced hydraulic team in the Eden Prairie, Minnesota. The team will take advantage of Eaton’s expertise in hydraulic components and system design as well as experience gained through R&D and installation of thousands of electric vehicle (EV) charging stations in public locations and residential areas throughout the United States. According to Dane Boysen, director of the U.S. Department of Energy’s Methane Energy Vehicle Program, “These innovative projects are expected to improve the economics and convenience of natural gas vehicles, make them into every American family and change the way we travel. I hope we can use these advanced technologies in the future. Technology, to supply sufficient domestic natural gas for transportation, to diversify the national fuel and gas product portfolio." Eaton will work with the University of Minnesota on thermodynamic analysis and modeling to ensure the efficient transfer of heat during the compression process. The refueling system will use liquid (acting as a piston) to compress natural gas. Innovative heat exchange technology will significantly increase efficiency and reduce costs. Chris Roche, Eaton’s vice president of corporate technology global innovation, said: “With the development of this breakthrough compressor and refueling system, Eaton will eliminate the major barriers to universal access to natural gas vehicles and trucks. Management Technology Eaton has a wealth of experience in solving the world's toughest hydraulic, electrical, and mechanical challenges. This project offers great opportunities for the use of critical alternative energy in a safe, efficient, and sustainable manner." The current cost of natural gas refueling systems ranges from $5,000 to $10,000. Eaton expects its prototype to be completed by the end of 2015 with a target production price of $500. Eaton provides a full range of EV charging stations for residential and industrial applications. It has a large market share in the North American charging market and has shipped or installed more than 2,000 charging stations. Compared with other processing methods such as canning and freezing, the processing method of dried fruit is relatively simple in equipment and operation, and the production cost is relatively low. The production process of dried fruit is: raw material pretreatment, blanching or soaking in alkali, sulfur fumigation, dehydration, wetting, sorting and packaging.

The pretreated fruit is heated with boiling water or steam or other methods for a short time, which is called blanching. The main purpose of blanching is to use heat to drive out the air in the fruit tissue and destroy the oxidase in the fruit to prevent oxidative discoloration. In addition, after the fruit is blanched, mesh-like fine cracks are formed on the surface, which can speed up the evaporation of water, shorten the drying time, and prevent the generation of large cracks during later heating; blanching can also eliminate and wash away the residue on the surface of the fruit. Microorganisms and dirt.
The temperature and time of blanching vary according to the type, variety, maturity, texture, size, etc. of the fruit. Generally, it is treated in boiling water for 5 to 15 minutes. The purpose of fruit soaking in alkali is mainly to remove the wax through the action of alkali, so as to facilitate the evaporation of water and promote drying. In addition, the fruit is immersed in hot lye, which can remove the microorganisms remaining on the surface and has a disinfection effect.
