According to Guizhou Hongfu Industrial Development Co., Ltd., the company will cooperate with Swiss Dawei Technology Co., Ltd. to build the world's first industrial equipment for the production of anhydrous hydrogen fluoride. The promotion of this technology will effectively promote the development of circular economy in China's phosphorus chemical industry.
The technology of preparing anhydrous hydrogen fluoride from fluorosilicic acid is the patent of Swiss Dawei Technology Co., Ltd. This technology recycles the wastes such as fluorine which have been disposed of in the original process, which is a potential economic benefit and significant environmental benefits. High-end technology is at the forefront of the current international. Technical pilot plants have been successful abroad.
Since 2003, the two sides have conducted many researches on the construction of the project, including investment risk, environmental benefits and economic returns. They believe that the time to apply this technology to industrial production is ripe, and the two sides reached an agreement to build this. The world's first industrial plant for the production of anhydrous hydrogen fluoride from fluorosilicic acid has made it a demonstration plant to promote the technology to the world.
At the end of 2005, Hongfu Industrial Development Co., Ltd. signed a contract with Swiss Dawei Technology Co., Ltd. to jointly build the device. The annual production capacity of the device is 20,000 tons, and the investment scale is 200 million yuan. The technology and core equipment of Swiss Dawei Craft Co., Ltd. have been started in January 2006. The construction period is expected to be 18 months, which can be July 2007. Put into operation.
