China’s Largest Nitric Acid Absorption Tower Successfully Developed

The core equipment of the nitric acid plant, φ4600mm nitric acid absorption tower, has been successfully developed in Sichuan Blue Star Machinery Co. The absorption tower will be used in the largest 150,000 tons/year domestic nitric acid plant. This marks that China has the ability to independently design and manufacture this kind of large chemical equipment at the world technology level. It fills a long-standing gap in this field in China. At present, the absorption tower has been shipped to the user enterprise Sichuan Meishan Jin Sheng Saerui Chemical Company. The φ4600mm nitric acid absorption tower is manufactured in 3 sections and assembled on spot. Its diameter is 4.6 meters. Its length is 63.1 meters. The weight reaches 246 tons, and the output value of a single unit is 12 million RMB. All these data created the highest data for Blue Star Machinery Company in 40 years. To improve the energy-saving and environmental protection performance of the equipment, so that the absorption rate of nitric acid mist reaches more than 99%, the tail gas nitrogen oxides ≤ 200ppm. It is necessary to ensure that the straightness deviation of any 3-meter-long cylinder section of the absorption tower must not be greater […]

EPA Joins DuPont to Prepare Nano-safety Guideline

In order to further evaluate the effectiveness, flexibility, and practicality of R&D in the field of nanotechnology by companies or research organizations, on June 21 the Environmental Defense Agency (Environmental Defense) announced the future release of the “Guidance on the Safety and Environmental Risks of Nanotechnology Product Development” prepared in collaboration with companies. In this collaboration, DuPont is responsible for conducting safety and environmental risk testing and developing guidance outlines for the nanotechnology development of three materials: titanium dioxide (titanium dioxide), carbon nanotubes, and zero-valent iron. “The EPA chose to work with DuPont on the above three projects to complete the assessment, not only because DuPont manufactures all three of these products, but also because it believes that DuPont’s current production and development model is representative of a typical company participating in this assessment.” Mr. Terry Medley, DuPont’s project leader, said. He also noted, “For DuPont, each of the three projects represents the core value chain of the industry. Because including raw materials, production, equipment, employees and many other links, DuPont has a very detailed deployment and arrangements, will help the U.S. Environmental Protection Association to successfully complete the task.” DuPont’s new titanium dioxide category is Light Stabilizer 210, a […]

Countries Are Experimenting with Cellulosic Ethanol Development

In the near future, the gasoline flowing in your car’s tank will not only be the barrel of increasingly expensive “black gold” dredged from the deep sea or underground. Leftover wood chips from lumber mills, farmers’ discarded straws, and rice hulls will all be turned into fuel that will make your car run faster. Cellulosic ethanol is seen as one of the most promising feedstocks for gasoline blends. Various countries are just starting in this technology now, and once someone is one step or even half a step ahead, it means huge commercial benefits. Unlike wheat-based ethanol, the new technology uses cellulose-containing straw and wood chips to produce ethanol. This replaces some of the gasoline, makes it clean and environmentally friendly, and reduces the cost of raw materials. At present, the internationally popular technologies for manufacturing ethanol from starchy products are divided into three categories: one is the use of food crops such as corn or wheat. The second is the use of non-staple grains such as sweet potato, cassava, sweet sorghum, etc. The third category is the production of waste organisms contained in crop straw, forestry processing waste, sugarcane bagasse and municipal waste, collectively known as cellulose. Of the […]

Huge Cost Overruns Make BASF Decide to “Stay Away” from Europe

Huge cost overruns make BASF decide to “stay away” from Europe The skyrocketing gas prices in Europe have made it difficult for many industrial companies to maintain. Recently, BASF officially announced that it would scale down its production in Europe as soon as possible and permanently. The reason it gave was the gas crisis in Europe and overly strict EU industry regulations. BASF’s natural gas costs have increased significantly this year. Faced with a huge cost pressure of about RMB 15.8 billion, BASF finally could not afford it and chose to stay away from Europe. Under the energy crisis, companies are struggling to support themselves. The European chemical industry is now facing a huge impact. This is mainly due to the serious spike in energy costs in Europe. BASF is not the only one that has been badly affected. Many European companies have had to cut production in order to struggle in this situation. For example, in Alcoa’s aluminum smelter in Norway, production was cut by one-third of the original. Total Energy and the German plant Crestron have even announced a direct shutdown. It can be seen that European companies are now walking on thin ice. As a result, many […]
