Because the environmental situation of China's petroleum and chemical industry is extremely serious, especially oil refining, coal chemicals, pesticides and other key industries, they are faced with recycling high concentrations of waste water, zero liquid discharge, dangerous to handle volatile organic gases and other environmental protection technical problems. The environmental problems have gradually become the biggest bottleneck in the development of chemical industry park, the park's pollution control and comprehensive management has come to a critical moment. To promote the application of advanced environmental protection technology and equipment in the oil and chemical industries, as well as to build a contact platform for equipment manufacturers and petroleum & chemical industry, in June this year, Beijing will hold the 2016 China's petroleum and chemical industry environmental technology and equipment supply and demand negotiation. The meeting will include: flue gas purification and sulfur recovery technology and engineering topics; high concentration organic wastewater treatment and zero liquid discharge thematic; VOCs and odorous gas treatment and other topics.

 

NOx is a major source of air pollution, the large number of NOx discharging directly into the atmosphere not only cause photochemical smog, but also result in acid rain, which corrodes buildings, damages vegetation, injuries personal and so on. The most effective method for removing NOx is SCR, which takes tungsten trioxide denitration catalyst as the core technology. Tungsten trioxide is an important intermediate state compound in the tungsten metallurgical industry, and a large number of it used in the preparation of tungsten powder, tungsten carbide, etc; Meanwhile, because tungsten trioxide has the capabilities of anti-curing, anti-sintering of carrier, it greatly enhances the performance of SCR denitration catalyst, thereby to improve the denitration efficiency.

 

With the continuous improvement of people's environmental awareness, environmental issues have received very much attention; and, also attached great importance to the national, the 12th Five-Year Plan of energy-saving projects has concluded the desulfurization and denitrification project in, and furthermore, thermal power, cement and steel industries are the top priority. Tungsten trioxide denitration catalyst is used in the SCR denitration projects after combustion, thus to achieve the goal of NOx removal, exhaust gas purification.
