A Feasibility Study On The Project Of The Waste Desulfurizer In Its Harmless Disposal And Recycling In The Hualing Lianyuan Iron And Steel Company

With the increased awareness of environmental protection, countries have also introduced more and more policies about pollution and environment protecting, and the social responsibility of corporates becomes more and more important. Enterprises not only ensure their own profitability, but also must ensure the damage that their production activities act on the environment as little as possible, or even eliminate the environmental pollution. Based on this, Hunan Hualing Lianyuan Iron and Steel Company starts a technical development project—"the harmless disposal and recycling of the waste desulfurizer in the Hualing Lianyuan Irom and Steel Group" in2009. The project has three aims:one is strengthening the management of hazardous waste, another one is implement the requirements of national environmental policy and the last is reducing costs and increasing efficiency within the company.At first, this paper describes the background and significance of the the research, related theory and the structure of the article, then it introduces the basic situation of the project. After we get a preliminary understanding about the situation of the Hualing Lianyuan Iron and Steel Company, we enter into the main body of this paper——the feasibility study of this project:At first, this paper introduces three commonly used treatments about waste desulfurizer. According to the basic data from the experiments, samples were prepared for the next test and evaluation. Combination of factors taken into account, we choose Oxygen-rich melt extraction steam blowing process as design program at last. Taking into account the temperature and solvent volume effect on the desulfurization regeneration, we can seek optimal parameters. Project that is validated by the laboratory and has the effect of field application can be finally put to use. So we arranged a two-phase site implementation, small-scale industrial test and regeneration of mass production. According to a series of experimental data obtained, we draw a scientific conclusion about the project, at last we do the technical and economic analysis of the project. Through the experimental study of the sound disposal and regeneration to the waste desulfurization, we find the solutions to the disposal problems of waste desulfurization, ultimately we achieve the purpose of reducing the consumption of fresh desulfurization.The exploration and analysis of this article find a more practical and more feasible new method in regeneration for the desulfurization, at the same time the method can reduce the pollution of the environment from desulfurization, reduce the production costs and at last promote sustainable economic and social development goals effectively.
