近几年来,法国氧、氮和稀有气体氩等压缩气体的装载和运输有很大发展。为了更好地运输这些产品就需要了解这些产品的基本性能和自然特性以及所运输的液化气体的性质。例如: (1)氮气,密度0.808,沸点温度-196℃; (2)氧气,密度1.141,沸点温度-183℃; (3)氩气,密度1.393,沸点温度-186℃。它们在达到临界温度-200℃时,便呈液体状态。这就要求车辆能在大气压力和低于沸点温度的液态形式下进行运输,并且要
In recent years, there has been a great development in the loading and transport of compressed gases such as French oxygen, nitrogen and rare gas Argon. In order to transport these products better, the basic and natural characteristics of these products and the nature of the liquefied gas transported need to be known. For example: (1) nitrogen, a density of 0.808, the boiling temperature of -196 ℃; (2) oxygen, the density of 1.141, the boiling temperature of -183 ℃; (3) Argon, density 1.393, boiling temperature -186 ℃. When they reach a critical temperature of -200 ° C, they are in a liquid state. This requires vehicles to be transported at atmospheric pressure and in liquid form below the boiling temperature, and to
