Multi-tube pressure vessel

A separation system comprising:

• a pressure vessel including a feed stream inlet, a residual stream outlet and at least two permeate stream outlets, the pressure vessel further including a feed reservoir in fluid communication with the feed stream inlet, a first permeate reservoir defined by a first tube sheet assembly and in fluid communication with at least one first permeate stream outlet, a cartridge chamber, a second permeate reservoir defined by a second tube sheet assembly and in fluid communication with at least one second permeate stream outlet, and a residual reservoir in fluid communication with the residual stream outlet, the first tube sheet assembly including a first tube sheet, a second tube sheet and a plurality of first sleeves disposed therebetween, the second tube sheet assembly including a third tube sheet, a fourth tube sheet and a plurality of second sleeves disposed therebetween, the plurality of second sleeves corresponding to the plurality of first sleeves;
• a plurality of membrane cartridge assemblies disposed within the pressure vessel and extending from the feed reservoir to the residual reservoir, each membrane cartridge assembly including, a first permeate adapter including a plurality of first permeate discharge ports in fluid communication with the first permeate reservoir, a second permeate adapter including a plurality of second permeate discharge ports in fluid communication with the second permeate reservoir, and a membrane cartridge including a permeate passage tube extending from a first end to a second end of the membrane cartridge, the first permeate adapter disposed within one of the first sleeves and in fluid communication with the feed reservoir, the first permeate adapter joined to the first end of the membrane cartridge and further joined to a first end of the permeate passage tube, the second permeate adapter disposed within the corresponding second sleeve and in fluid communication with the residual reservoir, the second permeate joined to the second end of the membrane cartridge and further joined to a second end of the permeate passage tube.
