•液化石油气中含有少量未分离干净的乙烷、乙烯(两者简称C2)和戊烷(简称C5)、已烷(简称C6)等烃类, C5、 C6在常温下不易气化,它们与未脱除干净的水份等液体称为残液。

•液化石油气无色无味。日常使用的液化石油气中加了一种特殊的气体,一旦发生泄漏,微小浓度都可察觉。

•液化石油气本身无毒。但人在充满液化石油气的室内,会感到不适,大量吸入时,会麻痹神经或缺氧窒息,可能发生意外。

•如丙烷的临界温度96.75℃,温度15℃时加压至0.69~0.78MPa即可液化,丁烷的临界温度152.8℃, 15℃时加压至0.39~0.49MPa即可液化。

•YEHUASHIYOUQIDEQIHUA

•液化石油气各组分的沸点很低,常压下丙烷在-42.17℃即处于沸腾状态(液体从内部开始气化称沸腾)。液态液化石油气减压或泄漏时迅速气化,吸收大量热量,若与人体接触可能造成冻伤

•丙烷0~50 ℃范围内比水的膨胀系数大13倍。如果密闭容器、液化气钢瓶、液化气罐充满液态液化石油气,温度升高1℃,则容器内压力升高2~3MPa,可能引起容器爆破。

•由表可见气态液化石油气比空气重(约为空气的1.5~2倍),不易扩散至上空,一旦泄漏易积存于低洼、沟槽处,形成爆炸性气体。液态液化石油气比水轻(约为水重的0.5~0.6倍)。 在地面储罐底部泄漏抢修时用到的注水法就是利用液态液化石油气比水轻的特性,在底部将水加压注入储罐,让液态液化石油气浮在上面,流出来的是水,为进一步抢修创造条件。
