Ai Kewen said that at present, Praxair has 3,000 independent patents. In 2004, Praxair invested US$77 million in R&D projects. In addition, the investment for the construction of the new plant and the latest technology reached 634 million U.S. dollars. In the past 100 years, Praxair has developed many technologies and is widely used in various industrial fields such as steel and metal manufacturing, chemicals, energy, aerospace, electronics, healthcare, large-scale manufacturing, glassmaking, wastewater treatment, and food processing to help customers. Improve productivity and environmental benefits. Technology plays a very important role in the development of Praxair.
Ai Kewen believes that since its establishment in 1907, Praxair has two comprehensive technologies worth mentioning: one is to develop the most efficient supply system for the production of industrial gases; the other is the application of new technologies, that is, the use of the company's industry. Gas helps customers solve productivity, cost, and environmental issues.
For the application of new technologies, a typical case is the development of vacuum pressure swing adsorption equipment for oxygen production. In the 50s of last century, Praxair's predecessor invented the synthetic zeolite molecular sieve. In the 1970s, the vacuum pressure swing adsorption system process was developed. At present, a new technology that combines molecular sieves, vacuum pressure swing adsorption equipment, and processes enables oxygen production to maximize energy efficiency and minimize costs. In China, this technology has been widely used in many devices.
Another example of a typical application technology is the Jet Jet Technology (CoJet), which injects oxygen into steel. This technology is called the latest practice in iron and steel smelting innovations. The bundling jet is a laser-like supersonic oxygen stream injected into a steelmaking furnace, so that oxygen can reach deeper in the steelmaking furnace, more effectively mix with the furnace material, so that the steel enterprises increase production efficiency and Product quality while reducing costs. This technology has been commercialized in China for electric arc furnaces and oxygen top blown converters.
Ai Kewen said that Praxair is an industrial gas company focused on enabling the company's products and technologies to better help customers solve practical problems such as productivity, cost, product quality or environmental protection. The company is very concerned about safety and environmental issues. Praxair's technology ensures that the company can do new technology development according to local needs. In China, since the establishment of the first joint venture in 1992, Praxair has provided Chinese users with advanced on-site aeration wastewater treatment systems, bundled jet technology, and help coal-fired power plants to improve efficiency and reduce the oxy-fuel combustion of sputtering. Advanced technologies and equipment such as technology, and through advanced on-site gas supply systems, provide customers with the safest, lowest-cost industrial gases. In addition, Praxair's technology in China also includes the latest ultra-high-purity atmospheric gas systems and advanced gas monitoring systems. These technologies can provide relevant information for the management of critical impurities and technical analysis of the plant, so that the company's production meets high standards. standard. Currently, Praxair has 10 joint ventures and 12 wholly-owned companies in China. At the same time, it is also the initiator of the China Economic and Technical Alliance.
Ai Kewen pointed out that in the past 10 years, Praxair's annual sales growth rate of 9%, annual revenue growth of 13%. In order to maintain this performance, it is necessary to achieve in technological innovation: through the application of new technologies, the company will develop faster than the industries it serves; using advanced supply systems to reduce the supply costs of new plants, and further improve the stability; Whether it is a new plant or an already built plant, productivity can be improved by using advanced process optimization technologies and control systems. In China, the company must make its contribution to supporting economic development, efficient energy use, and improving environmental quality while trying its best to meet the needs of the domestic market.
As a top 500 US company and the world's top 50 chemical companies, Praxair has been in. In an interview with the reporter, Ai Kewen, director of the Asia-Pacific research and development center of Praxair, pointed out that continuous technological innovation is the basis for achieving this goal.
