A suction duct is disposed within a shell and tube heat exchanger. The suction duct is located relatively high and above the tube bundle so as to not entrain liquid or droplets that may be splashing and spraying upward. The suction duct is configured with an area schedule in fluid communication with a flow path inside the suction duct. The flow path is in fluid communication with an outlet of the shell. This is advantageous relative to traditional top of the shell outlets which generally have higher vertical footprints. The area schedule of the suction duct can facilitate and/or maintain relatively smooth vapor flow within the shell. The area schedule can achieve vapor flows that have some uniformity along the length of the shell, which can manage and/or avoid localized vapor flow and/or local currents, such as where high velocity may be present and where entrainment can result. 种抽吸导管，该抽吸导管设置在壳管式热交换器内。该抽吸导管定位成相对较高并且定位在管束之上，以使得不夹带可能向上喷溅和喷射的液体或液滴。该抽吸导管构造成具有区域安排，该区域安排与抽吸导管内部的流动通路流体连通。该流动通路与壳体的出口流体连通。这与壳体出口的传统顶置相
