摘要:
The air separation unit includes a single adsorption bed downstream of a reversing blower and configured to operate on the principle of vacuum swing adsorption. An optimal ambient air pressure to vacuum pressure ratio within an adsorber vessel downstream of the reversible blower is identified. When the air separation unit is operated at ambient conditions where ambient air pressure is different, such as at higher altitude (or lower altitude) a pressure ratio across the blower when drawing a vacuum on the adsorption bed is maintained for optimal blower power to oxygen production performance. Time for recovery of the adsorption bed can also be modified due to the lower absolute pressure achieved within the adsorption bed when the pressure ratio across the blower is maintained. An ASU is thus provided which is optimized for performance at various different altitudes without requiring modification of equipment within the ASU.
摘要(中):
空气分离单元包括在反向鼓风机下游的单个吸附床,并且被配置为基于真空摆动吸附原理操作。 鉴定在可逆鼓风机下游的吸附器容器内的最佳环境空气压力与真空压力比。 当空气分离单元在环境空气压力不同的环境条件下运行时,例如在较高的高度(或较低的高度)下,在吸附床上抽真空时,保持鼓风机两端的压力比,以获得最佳的鼓风机功率以产生氧气 性能。 吸附床的回收时间也可以由于在保持吹风机两端的压力比时在吸附床内达到的绝对压力降低而被改变。 因此提供了ASU,其针对不同高度的性能进行了优化,而不需要修改ASU内的设备。
