To solve the problem of H2S content in gas higher than national standard,we improve the desulfurization process,reform the desulfurization equipment,and use new type of more effective 888 desulfurization catalyst to produce qualified city gas.
The numerical simulation on the internal flow field of atomizing nozzle is conducted by using the computational fluid dynamics(CFD) software Fluent,which provides an accurate,economical and prompt method for optimized design of the nozzle and is significant to speed up the indigenization of the desulfurization equipment.
Except for advantages that combustion efficiency is similar to pulverized coal boiler,cheap desulfurization equipment,low operation cost,relative low NOX emission concentration,circulating fluidized bed boiler has a fatal weakness,namely,N2O emission concentration is higher than pulverized coal boiler.
The clean coal briquette technology for industrial boilers can not only greatly reduce the emission of sulfur dioxide and flue dust without any desulfurization equipment and dust collector installed, but also improve the combustion properties of coal.
With a view on the present state of lay behind of flue gas desulphurization equipment as regards production capacity developmental requirements and the backwardness of its reliability and controllability,the paper urges as the preferable option,to develop a desulphurization technique which is cheap,efficient and reliable.
The characteristics of coal desulphurization equipment are analyzed, the technological process about reasonable choosing are discussed in this paper,the optimal building and improving plan for Xishan and high-sulphur coal mine are suggested.
Based on the industrial test about the TS-35 desulphurization facility with ammonia, factors affecting desulphurization efficiency are investigated, including fume volume, SO_2 concentration, coal banks, ammonia flux, ammonia concentration and so on.
The main features and running result of Simplified Flue Gas Desulfurization System in Weifang Chemical Plant are introduced in this paper.The device possess the merits of high desulfurization efficiency,low gas pressure loss,low operation cost,less land occupation and disposal flue gas with waste etc.
With a view on the present state of lay behind of flue gas desulphurization equipment as regards production capacity developmental requirements and the backwardness of its reliability and controllability,the paper urges as the preferable option,to develop a desulphurization technique which is cheap,efficient and reliable.The paper presents an introduction to a number of techniques,and recommends the ganeral use of the wet absorption technique with electric charge activation.
