常减压装置-初馏塔模拟求助？ (1) 不一定按照实际参数就能收敛，实际参数有可能有偏差，适当调整某些参数是必要的。像初馏塔或者常压塔开始模拟时尽量保证较大的冷回流，这样更容易收敛一些，收敛后再慢慢往实际数据调整； (2)对于常压塔冷凝器温度高，塔顶回流罐应该设置气相采出，设置过冷后温度为40℃即可； (3)对于该点论坛里已经有很明确的讨论，你可以搜索下。“the free-water option is often used in refining applications to simulate crude/vacuum units. liquid crude and water don't mix. they form two separate phases. since the solubility of most crudes in water is very low, the water phase may be treated as pure. this simplification should not be used for chemical applications where rigorous two liquid phase flash calculations should be used. 查看更多
