Abstract: The invention relates to a system for the discharge and/or distribution of a gas from a source of the gas, and more specifically relates to such a system which enables gas from a source to be discharged and/or distributed to at least two gas-utilizing units irrespective of the operational status of each unit. The gas from the source is conducted from a manifold to each unit via respective conduits. Each conduit has a valve having a maximum closed position, in which the valve is open to a predetermined minimum degree exceeding zero, and a maximum opened position, in which it is open to a predetermined extent set by the maximum gas capacity of the respective unit. One valve maintains a gas flow delivery pressure to its respective unit not exceeding a selected maximum pressure. The other valve maintains a gas flow-rate corresponding to the gas-requirement of its respective unit. Means are provided for on-stream diversion and discharge of gas passing to each unit to permit emergency independent shutdown of each unit. Accordingly, discharge of gas from the source can always take place irrespective of the operational status of the units to which the gas is distributed and without causing excessively high back-pressures at the source when the units are inoperative. In a specific embodiment, the source is the regenerator of a catalytic cracker, one unit is a CO-boiler and the other unit is a CO-furnace.

Abstract translation: 本发明涉及一种用于从气体源排出和/或分配气体的系统，更具体地涉及这样的系统，其使来自源的气体能够排放和/或分配到至少两个气体 - 利用单位，而不考虑每个单位的运行状况。 来自源的气体通过相应的管道从歧管传导到每个单元。 每个管道具有阀门，该阀门具有最大关闭位置，其中阀门打开至超过零的预定最小程度，以及最大打开位置，在该最大打开位置，该阀门打开到由相应单元的最大气体容量设定的预定范围 。 一个阀将气体输送压力保持在其相应单元不超过所选择的最大压力。 另一个阀维持对应于其各自单元的气体需求的气体流量。 提供了用于通过分流和排出通过每个单元的气体以允许每个单元的紧急独立关闭的装置。 因此，无论气体分配的单元的工作状态如何，始终发生来自源的气体的排放，并且在单元不工作时不会在源处造成过高的背压。 在一个具体实施方案中，源是催化裂化器的再生器，一个单元是CO锅炉，另一个单元是CO炉。
