一、液化石油气一、什么是液化石油气液化石油气是石油开采和炼制过程中的副产物。主要成分是丙烷(C_3H_8)和丁烷(C_4H_(10)),它们在常温常压下是以气态存在,降低温度或增加压力,则会变成液体。为贮存及运输方便,一般是加压使其变成液体装在受压容器内,因此人们称之为液化石油气,简称液化气。二、液化石油气的主要物理性质液化石油气的物理性质(见表1)包括其比重、临介压力、临介温度、沸点温度和蒸发潜热等等。
First, the liquefied petroleum gas First, what is the liquefied petroleum gas Liquefied petroleum gas is a byproduct of oil exploration and refining process. The main components are propane (C_3H_8) and butane (C_4H_ (10)), which are in the gaseous state at normal temperature and pressure, reduce the temperature or increase the pressure, it will become a liquid. For the convenience of storage and transportation, it is usually pressurized to turn it into liquid in the pressure vessel, so people call it liquefied petroleum gas, referred to as liquefied gas. Second, the main physical properties of liquefied petroleum gas The physical properties of liquefied petroleum gas (see Table 1), including its proportion, the provisional pressure, the media temperature, the boiling temperature and latent heat of evaporation and so on.
