Magnetic energy whitening: A new approach for ultra-clean purification of yellow phosphorus exhaust gases

Thread Content

From February 25th to 27th, 2025, the China Phosphorus Chemical Industry Development Conference, the 4th Forum on the Innovative Development of Phosphorus-Based New Energy Materials, and the 1st Exhibition and Exchange Event on Digital and Intelligent Technologies and Equipment for the Phosphorus Industry were all held simultaneously in Yichang, Hubei. Yang Quanhong, the operations director of Shandong Baolan Environmental Protection Co., Ltd., gave a detailed presentation at the meeting on the applications of magnetic energy whitening technology in various domestic and international scenarios, including the phosphorus chemical industry, as well as the principle behind this technology. Yang Quanhong explained that “magnetic energy whitening removal” refers to the process technology and devices that utilize magnetic energy to eliminate white smoke, effectively removing the mixed pollutants present in such smoke so as to achieve \"ultra-clean emissions\". The white mixed pollutants include harmful substances such as dust particles, acid mist, alkali mist, aerosols, soluble salts, PM10 (inhalable particulate matter), PM2.5 (fine particulate matter), and CPM (condensable particulate matter), as well as substances like white smoke, black smoke, blue smoke, and yellow smoke. After treatment using magnetic energy to eliminate these white colors, the \"online monitoring\" values of these harmful substances come close to zero, eliminating unpleasant odors while also reducing visual pollution. As soon as the magnetic energy whitening technology was introduced, it immediately caught the attention of academic and business representatives present at the event, who gave it high praise. In front of the company’s booth, a steady stream of representatives came to visit and exchange ideas, seeking information on magnetic energy whitening technology as well as discussing potential cooperation opportunities. Leaders of phosphorus chemical enterprises in Wuhan invited the magnetic energy whitening technology team from Baolan Environmental Protection to conduct technical exchanges on site. Phosphorus chemical enterprises from Yunnan, Guizhou, Sichuan and other places also came for consultations. The managers of phosphorus-based fine chemical enterprises from Guangxi put forward new business requirements, seeking solutions for capturing substances such as aerosols and water vapor... Why has the magnetic energy whitening technology gained the favor of the attendees at the Phosphorus Chemical Industry Development Conference? Yang Quanhong believes this is thanks to the core advantages of this technology at present. Industrial flue gas that has undergone conventional treatment equipment and processes produces white plumes upon emission, while also leaving behind residual mixed pollutants such as phosphoric acid, phosphorus pentoxide, and nitrogen oxides. Bao Lan Environmental Protection has been specializing in the treatment of industrial waste gases for 11 years. The magnetic de-colorization device it has developed utilizes magnetic coupling and separation technology to remove various pollutants present in flue gas, such as particulates, phosphides, soluble salt particles, CPM, PM2.5, and aerosols. This device offers both safety and cost-effectiveness, serving as a \"booster\" and \"shield\" for enterprises to achieve green and high-quality development. It is reported that the magnetic energy whitening technology device possesses entirely independent intellectual property rights, having already been granted 16 **patents for invention. The magnetic energy whitening process has been tested in production environments at various phosphorus chemical companies such as Yunnan Jianglin Group and Yunnan Huofa Phosphating, and it has proven to be an effective tool for helping companies in over 30 industries, including those in the phosphorus chemicals, steel, coking, and pharmaceutical sectors, to meet environmental regulations while reducing costs and increasing efficiency. It serves hundreds of enterprises across the country that have needs related to flue gas treatment. According to Yang Quanhong, who introduced the matter to enterprise representatives who came to the exhibition for exchanges, the newly upgraded magnetic energy whitening process developed by Baolan Environmental Protection not only holds environmental benefits but also offers certain economic advantages. The new generation of magnetic energy whitening devices redefine flue gas treatment equipment in terms of both design and functionality, having been crafted into \"artworks\" among industrial products! Yang Quanhong said that magnetic energy-based whitening technology will enable future chimneys to stop emitting smoke, odors, or thick fumes. In the future, chimneys will no longer have their current tall, circular design; instead, they will evolve to feature elements such as landmark status, artistic design, ecological compatibility, compact size, and invisibility. The once troublesome chimneys have become new landmarks for corporate brand promotion, as well as a beautiful sight in the effort to build an ecological civilization.
