液化石油气属无色的易燃易爆气体.由于液化石油气发热量高(为焦炉煤气的6倍),使用方便,因此,广泛地在生产和生活中用作燃料.由于人们对液化石油气的“脾气”尚未摸透,不懂它的火灾危险性,在生产、储存、运输及使用过程中,往往处理不当,发生事故,这就可能带来灾难性的后果.液化石油气的来源石油气是丙烷、丁烷、丙烯、丁烯及少量其它碳氢化合物组成的混合物.在常温常压下是气体,经加压液化而成为液化石油气.液化石油气既可以从开采石油及天然气的过程中获得,也可由石油催化裂化过程中提取.目前我国许多城市使用的液化石油气主要是从石油裂化过程中分离制得的.液化石油气的危险性
Liquefied petroleum gas (LPG) is a colorless, flammable and explosive gas, and is widely used as a fuel in production and daily life due to its high heat generation (6 times that of coke oven gas) and its ease of use. The “temper” of LPG has not yet been fully understood and its fire risk is not known. In the course of production, storage, transportation and use, it is often handled improperly and an accident occurs. This may have catastrophic consequences. Source LPG is a mixture of propane, butane, propylene, butylene and a small amount of other hydrocarbons, which is gas at normal temperature and pressure and is liquefied to liquefied petroleum gas by liquefaction under pressure. Liquefied petroleum gas (LPG) Natural gas can also be extracted from the process of petroleum catalytic cracking.At present, the liquefied petroleum gas used in many cities in our country is mainly produced from the process of petroleum cracking.The risk of liquefied petroleum gas
