Abstract: A system for re-starting an air separation plant after an interruption in operation wherein descending liquid is collected in a non-operating distillation column and passed back to the separation section of that column before or upon re-start. The invention may employ a collection device situated in the column above the sump. Upon interruption in operation, the collection device accumulates descending liquid. From the collection device, liquid may be passed outside of the column and transferred to a holding vessel to re-inventory internal material of the column upon resumption in operation.
Abstract translation: 一种用于在操作中断之后重新启动空气分离设备的系统，其中将下降的液体收集在不操作的蒸馏塔中，并在再起动之前或之后返回到该塔的分离段。 本发明可以采用位于贮槽上方的塔中的收集装置。 在操作中断时，收集装置累积下降的液体。 从收集装置中，液体可以在塔的外部通过并转移到储存容器中，以在操作中恢复时重新盘存柱的内部材料。

Abstract: The invention comprises a downflow shell and tube condenser, especially useful for cryogenic rectification, which includes a shell having an upper tube sheet and a lower tube sheet, the shell extending above the upper tube sheet to create a first reservoir. A plurality of heat transfer tubes extend between the upper tube sheet and the lower tube sheet and also pass through the lower tube sheet. Cold liquid entering the heat transfer tubes flows down through the tubes and causes a condensation of vapor that is in contact therewith within the shell. The cold liquid is at least partially vaporized and exits from the lowermost ends of the heat transfer tubes.
