Liquid Chlorine Storage Area Safety
Design Control and Research
Abstract
Liquid chlorine is the chlor-alkali industry main products, it is widely used in industrial
production. However liquid chlorine is the play drugs, if it leakage the environment and people would be caused serious harmful. This paper based on the physical and chemical properties ,
analysis for liquid chlorine tank zone risk ;analysis for the safety of liquid chlorine tank domestic
status and countermeasures .Puts forward the right way for storage and selection of the reasonable
tanks; According to the architecture design code of fire design the safety spacing for liquid
chlorine tank, including the safe spacing of tanks between with each other; Tank and the
surrounding workshop safe distance, tanks area and outdoor substation, pump room safe distance etc; design for liquid chlorine of thunder, antistatic, fire protection. Choice of analysis for liquid
chlorine accident model, calculate the spread of chlorine gas and the radius of the deadly
consequences of accident injuries radius and forecast for the subsequent personnel, transfer and
division, and provide basis for dangerous area,puts forward some control measures and
suggestions to chemical enterprise of safety management work.
Key words:Liquid chlorine;tank area;safety distance;leakage
