Abstract

BLEVE; aşırı ısıtılmış bir sıvının atmosferinde basınç altında ani salınım olarak bilinir. Bu ani salınımların nedeni, tankın etrafındaki yangınlar, korozyon, tankın içinde aşırı ısınma nedeniyle oluşmaktadır. Yangın vs. olay bir kabı veya tankı etkiliyorsa, kabın sıvılaştırılmış gazında yüksek basınç olan bazı değişiklikler gözlenir. Bu araştırmada BLEVE olaylarına odaklanılmıştır. Bu tür olayların insanlar ve çevre üzerinde belirli bir olumsuz etkisi vardır. Bu sonuçlar, damarların parçalanması, alev oluşumu, aşırı basınç ve termal radyasyon etkileridir. Bu çalışmada, aşırı basınç, ateş topu gibi BLEVE sonucunda ortaya çıkabilecek etkileri analiz edilmiş ve insanlar ile çevre üzerindeki etkisi değerlendirilmiştir. Patlama / yangın kaynağından uzaklaştıkça yanıkların yoğunluğunun azaldığı tahmin edilmektedir.

The Assessment of Bleve Based Accident Impacts

Abstract

BLEVE; is known as a sudden release under pressure in the atmosphere of a superheated liquid. Because of the fires around the tank, corrosion, overheating inside the tank, the reason for these sudden swings. Fire, etc. If the event affects a vessel or tank, some changes are observed in the vessel's liquefied gas, which is high pressure. In this research was focussed on BLEVE incidents. Such incidents forms have a certain negative effect on people and the environment. Such results are formation of fragmentation of the vessels, formation of flame, overpressure and thermal radiation effects. In this study, analyze the effects that could occur as a result of BLEVE, such as overpressure, fireball, and assess the impact it had on people and environment. The intensity of the burns as we step away from the source of the explosion / fire has been estimated to decrease.
