(Abstract)
In recent years, there has been a fire and explosion accident caused by flammable liquids and gases, which have been attracting social attention As a result of analyzing the cause, many accidents occurred due to electric ignition sources such as static electricity and spark in the state where explosive atmosphere was formed due to the leakage of flammable liquid and gas.
Therefore, electrical appliances and equipment installed in the area should be explosion-proof type in the area where explosive hazard is stored in the places where flammable liquids and gases are stored and handled.
On the other hand, the standards of KS C IEC 60079-10-1 ~ 2, which are applied to the explosion prevention-related laws and standards such as the explosion dangerous area setting in Korea, are generally comprehensive and declarative standards. Therefore, It can be cited as the country or the industrial nose.
Therefore, the explosion prevention-related technical standards are not clear, so other standards or standards such as the country code, API, EI-15 must be applied. Therefore, it requires extensive knowledge of breadth and experience, However, in Korea, there are not many technical personnel with extensive knowledge and extensive experience in the field of electric explosion prevention
Therefore, in order to minimize the confusion caused by the lack of laws and regulations on the establishment of explosion hazard areas, and to provide information for setting the range of explosion hazard areas more accurately, five scenarios that are likely to occur in the chemical process are set up, The risk-based approach and procedures are presented.
In addition, the risk range according to the leakage source size according to domestic and foreign codes and standards is set, and compared and evaluated, and the appropriate leakage source size can be selected, In addition, the effect of the ventilation class and effectiveness on the risk range as the wind speed of the workplace increased was evaluated In addition, the explosion risk range design method was proposed by analyzing the effect of increasing the vapor pressure on the danger range when the temperature of the workplace increases depending on the process characteristics and seasons.
On the other hand, in order to calculate the appropriate amount of steam evaporation from the liquid pool of the flammable liquid which is not specified in the regulations, standards, etc., various evaporation model equations are applied to calculate leakage amount,
〔Keyword〕 Explosion hazard area, Explosion prevention, release source, ventilation rate, flammable liquid, vapor pressure, volatility.
