Liquefied petroleum gases, such as propane and butane, have not been included as they are too numerous to mention. 由于它们数量众多,无法一一提及,液化石油气体,如丙烷和丁烷没有包括在这里。
The mineral products such as salt, solvent naphtha, cement, liquefied propane, liquefied butane and liquefied petroleum gas; 盐、溶剂油、水泥、液化丙烷、液化丁烷、液化石油气等矿产品;
Will have a normal temperature and pressure can not be a large number of liquefied gas-methane to butane. 的过程中,会产生大量常温常压不能液化的气体&甲烷到丁烷。
With computing different media and inner diameters of pots, a rule whether a liquefied petroleum pot filled with propylene, propane, butane and butylenes could be checked according to vacuum condition in the low temperature was found. 对不同的介质和不同的贮罐内径进行了计算,找出了处于环境低温下装有丙烯、丙烷混合液化石油气、正丁烷、异丁烷、丁烯、丁二烯的液化石油气贮罐可否按真空校核的规律。
