气液平衡条件下氨的性质
图和表格显示了液态和气态氨的性质如何沿着沸腾/凝结曲线(温度和压力之间的三点和临界点条件)变化。氨相图包括在内。
在标准条件下,氨是气体。然而,在低温和/或高压下,气体变成液体,在更极端的条件下,变成固体。氨相图显示了随着温度和压力变化的相行为。三相点与临界点之间的曲线显示了氨沸点随压力的变化。
临界点:压力-温度曲线的终点,表示液体和蒸汽共存的条件。在较高的温度下,气体不能仅靠压力液化。在临界点,由临界温度T定义c和临界压力Pc时,相边界消失。
氨的临界温度:405.56 K =132.41℃= 270.34°F
氨临界压力:112.08 atm = 113.41 bar = 11.357 MPa (MN/m2) = 1647.2 psi (=lbf/2)
三相点:一种物质的三相(气体、液体和固体)在热力学平衡中共存时的温度和压力
氨三点压力:0.0601 atm = 0.0609 bar = 6090 Pa = 0.8832 psi (=lbf/2)
氨的三点温度:195.5 K = -77.65°C = -107.77°F
