In order to meet the demand of blast furnace injection, it needs to change lump coal into powered coal which size is under 75um. Because pulverized coal is explosive and flammable, safety requirements need to be stricter in the grinding process. Therefore, online monitoring system is required for the grinding process to ensure production safety during the preparation of coal.
In the variety of coal utilization, coking process has the highest coal utilization and will have about 75% coke and other 25% will be coal gas and chemical products. Coking process is to put powdered coal into coke oven after blending and a series of physical and chemical changes would occur to the powered coal in high temperature condition. The generated coke oven gas has various impurities so that it needs to be purified before using. Installation of online monitor benefits to increase productivity and quality as well as controlling pollutant emission concentration.
Modern electrolytic aluminum production industry mainly uses Cryolite-Alumina molten-salt electrolysis. The main waste gas in electrolytic aluminum production is CO2 and gas-solid fluorides as HF gas. It can monitor gas components to control emission of pollutants and recycle of fluoride.
In the production process of NSP cements, consumption of powered coal is mainly consumed in two equipment: rotary kiln for clinker calcining and decomposing furnace for calcium carbonate. In order to know the fuel utilization in the rotary kiln and decomposing furnace. The main method to monitor fuel combustion is to monitor gas components.
Waste incineration power generation is a solid waste treatment which is harmless, waste reducing, and resource recycling. However, in the process of waste incineration it will generate many toxic and hazardous gases, especially acid gases (SO2 and HCl) which would cause serious pollution to the environment. In order to meet environmental emission requirements, monitoring gas components is needed to control the toxic emission.
Coal-fired power plants are main pollution source of flue gas, SO2 and NOx, etc. The pollution from Coal-fired power plants severely destroy living environment and ecological environment. Monitoring gas components is the main way to control process and exhaust emission, optimize industrial process and it can achieve ultra-low emissions.
Fluid Catalytic Cracking Technique is an important mean to improve the efficiency of use of oil resource in oil refining industry. Poor quality of crude oil and strict requirements of environmental department push the development of Fluid Catalytic Cracking Technique. Enhancing heavy-oil refining capacity, improving product quality, reducing pollutant emission and raising economic efficiency are the starting point of the technique.
In some places which have rich coal but rare oil, it needs to transfer high-energy acetylene into basic acetylene as chemical material from coal and electricity. Through gas regulatory management and improvement of acetylene production process with calcium carbide technique, it can not only improve working efficiency, but also satisfy demands of production technique better. It will help to increase economic benefits and lower environmental pollution.
