Sintering and pelletizing technique further processes iron making raw material into block and ball material which is suitable for blast furnace steelmaking .It would help to enhance resource efficiency, reduce costs, increase environment quality, reduce emission in the steelmaking process, and play an important role in the development of recycling economy. Installation of online monitor would optimize production process and reduce emission.

Steelmaking process is a big consumer of energy. Converter steelmaking will produce a lot of coal gas which contains 60%-70% CO. It is very important to recycle the coal gas in steelmaking process. A method for purifying and recycling coal gas is wet dedusting. The limitation of this method will left high dust content in the coal gas after processing. In order to make use of this gas, two dust remover needed to be set to remove dust on the back side. Through online monitoring by gas analyzer after treatment, the flue gas can be recycled when it meets recycling requirements to reduce energy...

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. P: Slight negative/...

Modern electrolytic aluminum production industry mainly use Cryolite-Alumina molten-salt electrolysis. The main waste gas in electrolytic aluminum production is C02 and gas-solid fluorides as HF gas. It can monitor gas components to control emission of pollutants and recycle of fluoride.

In the process of coal-fired power generation, pulverized coal is heated by Pulverized Fired Boiler with high temperature, and fly ash is sent out with flue gas and collected by dust collector. Fly ash is typical industrial solid waste in the process of coal-fired power generation. The main component of fly ash is alumina oxide which accounts for 15%-46%.Soda-lime sintering process which has been widely used at home and abroad is main method to extract aluminum on fly ash. It would optimize calcination process control and reduce emission by installing online gas monitoring system.

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 HCI) 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.

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. Cleaning and Dryingand neutralizing dewatering

Chlor-Alkali product is strong corrosive. In the manufacturing process, waste gas containing chlorine in raw material may pollute environment. It is necessary to monitor gas components to control process safety, increase production efficiency and protect process equipment in the Chlor-Alkali industry. Primary brine Cl2 — i—I Liquid Chlorine packing Brine dechlorination Caustic soda
