The present invention addresses to a high-pressure vessel for packaging hollow fiber type membranes with application in the field of separation process with contactors with membranes aiming at a compact device/piece of equipment configured for the packaging of hollow fiber type bundles that can be used for various fluid separation processes such as liquid-liquid, liquid-gas and gas-gas, capable of working at high-pressures, enabling adequate hydrodynamic conditions and easily scalable. It is called a module the general piece of equipment, consisting of the vessel (A or C), object of the present invention, and the membranes packed inside the vessel. This piece of equipment consists of a vessel inside which the membranes are placed (14), and two heads attached at the ends (B or D). Each head has two connection points, thus allowing this device to be used with membrane contactors-type separation systems, such as “classical” permeation systems (liquid-liquid, gas-gas, pervaporation).

Systems and methods of gas-liquid contactors for direct ocean capture and/or direct air capture are described.

The present invention relates to a humidifier for a fuel cell, the humidifier comprising: a humidifying module for humidifying a dry gas, supplied from the outside, by using a wet gas discharged from a fuel cell stack; a first cap coupled to one end of the humidifying module; and a second cap coupled to the other end of the humidifying module. The humidifying module includes: a mid-case, both ends of which are open; and at least one cartridge that is located inside the mid-case and includes a plurality of hollow fiber membranes. The distance between a second gas inlet and a second gas outlet, which are formed in an inner case of the cartridge, is greater than the distance between a first gas inlet and a first gas outlet, which are formed in the mid-case.

A heat exchanger for an oxygenator device has multiple hollow fiber membranes that each have a hollow portion through which a heat medium passes, wherein the fibers are wound as a cylinder body. Each of the hollow fiber membranes follows a path between opposing ends of the cylinder body which is tilted with respect to a central axis of the cylinder body and is wound around the central axis of the cylinder body, wherein a tilt angle θ with respect to the central axis ranges from 22° to smaller than 67°, and wherein a constituent material of each of the hollow fiber membranes has a Young's modulus E ranging from 2.6 GPa to 0.07 GPa. During winding, the hollow fiber membranes are stretched according to a stretching rate between 0.5% and 3.0% and then fixed at the ends to maintain the stretching.
