Low-temperature flue gas desulfurization and denitrification technology breakthrough large-scale promotion soon

Recently, China's low-temperature flue gas desulfurization and denitrification technology breakthrough. It is reported that the technology of simultaneous desulfurization and denitrification of low-temperature flue gas is jointly developed by MCC and Tsinghua University and has multi-pollutant synergistic control technology with independent intellectual property rights. The technology to achieve the country's super-clean thermal power industry emissions standards, and have large-scale promotion and application of the conditions.

Low-temperature flue gas desulfurization and denitrification technology breakthrough large-scale promotion soon

On March 22, the low-temperature flue gas desulphurization and denitrification technology developed independently by China Metallurgical Building Research Institute Co., Ltd. (hereinafter referred to as "MCC") was successfully applied to the 220-ton boiler of Nantun Electric Power Co., Ltd. of Yankuang Group Co., Ltd. Flue gas ultra-low emission devices, and successfully passed 168 hours at full capacity operational performance test, marking China's low-temperature flue gas desulfurization and denitrification technology breakthrough.

Simultaneous desulfurization and denitrification technology of low-temperature flue gas is a multi-pollutant synergistic control technology developed jointly by China Metallurgical Construction Research Institute and Tsinghua University. This technology solves the problems that low-temperature flue gas denitrification and conventional semi-dry desulfurization by-products are difficult to utilize The technology has achieved the desulfurization efficiency of 98%, denitration efficiency of 88%, the system outlet dust concentration of less than 5mg / m3, fully meet the national and local requirements for heating boiler environmental standards, prevention and control of air pollution is of great significance.

The Yankuang Group Co., Ltd. Nantun Power Branch 3x220 tons of ultra-low emission boiler flue gas transformation of the general contracting project for the China Metallurgical Construction Research Institute of low-temperature flue gas desulphurization and denitration dust removal technology for the first time in the 200-ton boiler application. After 168 hours of full load operating parameters of the preliminary analysis, the simultaneous desulfurization and denitration dust removal desulfurization efficiency of low-temperature flue gas can be more than 99% stable, denitrification efficiency can be more than 70% stable, dust emission concentration less than 5mg / m3, reaching the national Ultra-clean emission standards for the thermal power industry, and the operating cost is only about 40% of the mainstream dry-process ultra-clean emission technologies in China.

The successful application of the project marks that the technology of simultaneous desulfurization and denitration and de-dusting by low-temperature flue gas has been basically developed after ten years of R & D by MCCRI and has the conditions for large-scale popularization and application, providing technical support for the defense of blue sky.

Chlorinated Polyethylene

CPE Chlorinated Polyethylene 135A CAS 63231-66-3

Chemical and Physical Properties:

Product Name : Chlorinated Polyethylene

Molecular Formula: CH2-CHCl-CH2-CH2 n

CAS No.:63231-66-3

Production description:

Chlorinated polyvinyl chloride (CPE) is a saturated polymer material with a white powder appearance, non-toxic and odorless, and has excellent weather resistance, ozone resistance, oil resistance, flame retardancy and coloring properties, chemical resistance and aging resistance, Good toughness (still flexibility at -30°C).

CPE is a kind of crystalized white fine particle elastomer with good softness, hydrogen atomsare in special high density polyethylene replaced by chlorine atoms. Low brittle temperature, weather resistance, aging resistance make it impact and additive

modifier.
