A method of forming a degassing system includes the step of forming a bundle of hollow tube membrane members by wrapping hollow tube membrane members to form the bundle at a temperature above 100 F. (38 C.). Another method of forming a degassing system includes the step of the inserting bundle into an outer canister at a temperature above 100 F. (38 C.). A fuel supply system made by these methods is also disclosed.

The invention relates to a head plate, fixing the end of a tube bundle with a number of, in particular, porous tubes with a membrane in sealing manner. The head plate is made from a metal or a metal alloy with a melting point lower than the lowest failure temperature for a tube material and/or the membrane.

Degassers, degassing systems, and methods of using degassers to remove gas molecules entrapped or dissolved in a processing liquid. The degasser has a vacuum chamber with one or more walls; one or multiple inlets and one or multiple outlets through which the liquid is respectively passed into and out of the vacuum chamber, the inlet(s) and the outlet(s) penetrating the one or more walls; one or multiple separators located inside the vacuum chamber and being pervious to the gas molecules but impervious to the liquid; at least one vacuum for applying through a vacuum port a pressure differential across the separator(s) to cause the gas molecules to leave the liquid and to permeate through the separator(s) thereby removing the entrapped or dissolved gas from the liquid; and optionally one or multiple feed lines in fluid communication with the inlet(s) and two or more than two separators.

The present invention discloses a combination unit and method of multiple membrane shells. The combination unit of multiple membrane shells is formed by bundling multiple membrane shells in parallel, wherein the raw water port and the concentrated water port of each of the membrane shells are respectively connected and sealed with the raw water port and the concentrated water port of the adjacent membrane shells to form the shared raw water port and the shared concentrated water port which are respectively connected with the raw water pipeline and the concentrated water pipeline. Since each of the combination units of multiple membrane shells is provided with the shared raw water port and the shared concentrated water port, it is adequate to finish the assembly of the shared raw water port with the pipeline and the assembly of the shared concentrated water port with the pipeline in the engineering installation. The combination unit of multiple membrane shells can be placed horizontally or vertically. By adopting the technology of the combination unit of multiple membrane shells, there does not need a large number of clamps, the number of sealed points is decreased, the engineering cost is reduced, the hidden seepage danger is lowered, the engineering installation workload is lessened, the occupied area of the apparatus is saved, and the maintenance and the service are convenient.
