Environmental Risk Estimate Of Structure And Appliance In Formaldehyde Industry

Abstract:Recent years the formaldehyde industry in China grows rapidly and some large producing devices are built up constantly. This kind of firms are with great dangers, not only during the producing will it emit flammable and explosive or poisonous elements, but also under accidents it will have deep impacts with the surrounding environment. Consequently it is quite necessary to regulate the risk estimate of formaldehyde industry, build up such kind of management system to reduce the risks and damages to the environment.According to the formaldehyde industry's characters, this essay gives a summary on the base of deeply studying the current methods and technics. Setting Xiangzi Chemistry Firm as an example, it calculates the after-accident damage; using an canonical method to accurately analyze the target storing can under a stimulant largest accident, and after collecting the minimum cut-set and the minimum dia-set, the essay proposes some measures that can effectively prevent the formaldehyde leak out. At last it concludes local climate and geography conditions and information of protecting target as well as the toxicity character of formaldehyde, and finally predicts the probable damage level and the risks. All these are the base of scientific background for enterprises to carry out risky management, and the fruit of this essay can be a reference in an environmental risky estimate to the formaldehyde industry.
