Cytec Technologies, a wholly-owned subsidiary of Solvay Co., Ltd. (collectively referred to as "Solvay"), once again emphasized to the industrial market its multiple authorized patents on scale inhibitor products in China, and called on the industry to adopt Regular channels purchase the scale inhibitor products under the registered MAX HT® brand to achieve the expected effects of increasing efficiency, reducing costs, reducing energy consumption, and reducing emissions.
As the world's largest consumer and producer of aluminum, China's alumina industry is developing rapidly, especially the rise of new energy vehicles and smart home appliances in recent years, which has led to large-scale new alumina projects. The development of the industry has put forward higher requirements for the smooth and efficient operation of alumina equipment. The evaporation process is a vital link in the production of alumina, but it will cause fouling on the inner wall of the evaporator, which not only affects the heat transfer coefficient of the equipment, reduces the heat transfer efficiency, affects the production capacity of the equipment, causes the instability of the entire production, but also As a result, the entire process consumes more energy and increases production costs. In addition, in order to cope with the large amount of greenhouse gas and wastewater emissions in the alumina industry, the state has also proposed stricter emission standards for the industry.
The patented scale inhibitor product under Solvay's MAX HT® brand can effectively suppress aluminosilicate scaling in processes such as the Bayer process and help increase the cleaning interval of the dissolution section from once every 8-10 days to 45-60 days Clean once; the evaporation section is extended from 20-30 days to more than 90 days. And can effectively reduce CO2 emissions, save energy consumption, reduce sewage emissions, and save production and maintenance costs. It is estimated that for every ton of alumina produced, using MAX HT® can save 0.1-0.5 tons of steam, reduce CO2 emissions by 13-92 kg, and reduce pickling waste liquid by 0.9-2.7 kg. The long-term application of MAX HT® in more than thirty alumina plants around the world has brought significant benefits to energy conservation and emission reduction. Due to MAX HT®'s outstanding contribution to the environment, the technology won the Green Chemistry Award from the US Environmental Protection Agency in 2012.
Solvay scale inhibitor solutions are widely used in evaporators, heat exchangers and flash tanks, dual-flow stripping preheaters, heat exchange unit heaters and flash tanks for liquid condensation, interstage pipes, filtration And related pipes. Currently holds a number of authorized patents in China, and its effectiveness will continue to at least 2027, including: methods to prevent or reduce aluminosilicate scale in Bayer process, hydrophobically modified polyamine scale inhibitors, reducing alkali industrial processes Method and composition for medium aluminosilicate dirt.
"There are many products on the market that are suspected of infringing Solvay's scale inhibitors. In order to protect the use of our customers, we will continue to investigate the market. We will resolutely exercise intellectual property rights for suspicious infringements. Do our best to help the industry save energy and reduce emissions, "said Joe Chou, Sales Director of Solvay's Technology Solutions Division, Asia Pacific.
