No.63/404,877, filed on September 8, 2022, and U.S. Prov. Appl. No.63/404,887, filed on September 8, 2022, which are herein incorporated by reference in their entirety. BACKGROUND Field [0002] Embodiments of the present disclosure generally relate to membrane technology, and more specifically, dehydration membranes, methods for preparing such membranes, and methods for dehydrating fluids (e.g., gases and/or liquids) with such membranes. Description of the Related Art [0003] The process of separating, removing, or reducing water from a fluid, such as a gas mixture or a liquid mixture, is important in our daily life as well as in the chemical, petrochemical, and energy industries. For example, moisture is removed from the air to control humidity within the environment humans live and work. The process of removing moisture from structures or vehicles is critical to provide human comfort, prevent mold growth, and ensure durability of the structure or vehicle. In other aspects, the processes of removing water from a wide range of organic solvents, chemical intermediates, and products are commonly used in chemical and petrochemical industries. In further aspects, an example of water removal is the pervaporation process by which water is selectively removed through a membrane from liquids, such as organic solvents and monomers. [0004] The current commercial dehydration membranes, such as membranes based on cellulose acetate, have some limitations. For example, these dehydration membranes are susceptible to degradation when dehydrating organic solvents at temperatures of greater than 50°C. [0005] Therefore, there is a need for improved dehydration membranes and methods for preparing such membranes, and methods for dehydrating fluids with such membranes. SUMMARY [0006] Embodiments of the present disclosure generally relate to dehydration membranes which have one or more selective layers, methods for preparing such membranes, and methods for separating water from a fluid mixture with such membranes. The dehydration membranes are capable of permeating water selectively to a low-pressure or low-concentration permeate side at a greater transport rate than other fluid components. [0007] In one or more embodiments, a dehydration membrane is provided and includes a non-woven fabric backing, a porous support layer disposed on the non- woven fabric backing, and one or more selective layers disposed on or above the porous support layer. Each of the selective layers independently contains a selective polymeric material and at least one of the selective layers contains an ethylene vinyl alcohol polymeric material as the selective polymeric material. [0008] In some embodiments, a dehydration membrane is provided and includes a non-woven fabric backing, a porous support layer disposed on the non-woven fabric backing, a first selective layer disposed on the porous support layer and containing a first selective polymeric material, and a second selective layer disposed on the first selective layer. The second selective layer contains a second selective polymeric material. The first selective polymeric material, the second selective polymeric material, or both the first and second selective polymeric materials contains an ethylene vinyl alcohol polymeric material. [0009] In other embodiments, a dehydration membrane is provided and includes a porous support layer and one or more selective layers disposed on or above the porous support layer. Each of the selective layers independently contains a selective polymeric material and at least one of the selective layers contains an ethylene vinyl alcohol polymeric material as the selective polymeric material.

[0012] In other embodiments, a method for separating water from a fluid is provided and includes introducing a fluid mixture containing water and a base fluid to a feed side of a dehydration membrane, recovering or removing the water from a permeate side of the dehydration membrane, and retaining the base fluid on the feed side. In some examples, the fluid mixture contains air, natural gas, flue gas, syngas, biogas, a refinery gas, or any combination thereof. In other examples, the fluid mixture contains crude oil, fuel, organic solvent, a hydrocarbon gas, a hydrocarbon liquid, a product stream in a chemical or petrochemical facility, or any combination thereof.

DETAILED DESCRIPTION [0020] Embodiments of the present disclosure generally relate to dehydration membranes which have one or more selective layers, methods for preparing such membranes, and methods for separating water from fluids (e.g., gases and/or liquids) with such membranes. The dehydration membranes are capable of permeating water selectively to a low-pressure or low-concentration permeate side at a greater transport rate than other fluid components. Figures 1-4 depict cross-sectional views of dehydration membranes 100-400, respectively, as described and discussed in various embodiments herein. The dehydration membranes 100-400 are exemplary membranes and other variations of these membranes are in the scope on the present disclosure. [0021] Each of the dehydration membranes 100-400 has a feed side 102 opposite a permeate side 104. During water separation, a fluid mixture containing water and a base fluid (e.g., gas, liquid, or a combination thereof) is introduced to the feed side 102. The water is removed from the feed side 102, passes through the dehydration membranes 100-400, and is recovered from the permeate side 104. The remaining base fluid is retained, or substantially retained at the feed side 102. [0022] In embodiments described and discussed herein, each of the dehydration membranes 100-400 contain one, two, or more selective layers 130 which are used to selectively permeate water over other fluid components including one or more gas components and/or one or more liquid components. The selective layers, as described and discussed herein, are non-porous membranes which contain a dense selective polymeric layer without pores of greater than 10 Å. The spaces disposed between polymer chains in the non-porous membranes are 10 Å or less (e.g., about 1 Å to 10 Å) in diameter and selective water transport occurs by diffusion through these spaces. [0023] Figure 1 depicts a cross-sectional view of a dehydration membrane 100, such as a flat sheet membrane, as described and discussed in one or more embodiments herein. The dehydration membrane 100 contains a non-woven fabric backing 110, a porous support layer 120 containing a plurality of pores 122 and disposed on or above the non-woven fabric backing 110, and a selective layer 130 disposed on or above the porous support layer 120. As shown in Figure 1, the dehydration membrane 100 contains the selective layer 130 disposed directly on the porous support layer 120. In other embodiments, not shown, one or more other layers can be disposed between the porous support layer 120 and the selective layer 130. [0024] In one or more embodiments, the selective layer 130 contains one or more selective polymeric materials, such as one or more ethylene vinyl alcohol polymeric materials. As further described and discussed below, the selective layer 130 and/or the selective polymeric material can optionally contain one or more polyelectrolytes, one or more cross-linking agents, one or more functionalization agent, one or more catalysts, one or more types of metal nanoparticles, or any combination thereof.

In some embodiments, the dehydration membrane 200 contains similar layers as the dehydration membrane 100 but has two or more selective layers 130a, 130b (collectively referred to as selective layers 130). [0026] In other embodiments, not shown in the Figures, the dehydration membranes 100, 200 (as well as dehydration membranes 300, 400) can include any number of selective layers 130. For example, any of the dehydration membranes 100-400 can include a range from 1, 2, 3, 4, or 5 selective layers 130 to about 6, 7, 8, 9, 10, 12, 15, 20, 35, 50, 80, 100, 120, 135, 150, 180, 200, or more selective layers 130. In one or more embodiments, a plurality of selective layers 130 is disposed on or over the porous support layer 120, and the plurality of selective layers 130 contains from 2 selective layers 130 to about 200 selective layers 130.

The two air streams are separated by the dehydration membrane, and are flowing in a con-current, a counter-current, or a cross-current flow patterns. Due to the selectivity of the dehydration membrane, water permeates through the membrane from the high-humidity air stream to the low- humidity air stream.

As the result, water is removed on the feed side. The low partial pressure of water on the permeate side can be maintained using a vacuum pump or a sweep gas. The permeated water can be condensed and re-used.

In this separation process, the liquid that contains water enters a membrane unit on the feed side. Due to the selectivity of the dehydration membrane, water permeates through the membrane to the permeate side at a higher transport rate than other liquid components. As the result, water is removed from the liquid on the feed side while the other liquid components are retained on the feed side. The low partial pressure of water on the permeate side is maintained using a vacuum pump or a sweep gas. The permeated water can be condensed and re-used. To increase the water removal rate, the liquid entering the membrane unit is heated to about 40°C to about 80°C.
