Abstract: The invention discloses dual layer-coated membranes and methods for making and using these membranes. The dual layer-coated membranes have a relatively porous and substantial void-containing selective asymmetric membrane support, a first coating layer comprising a hydrogel, and a second coating layer comprising a hydrophobic fluoropolymer. The membrane support has low selectivity and high permeance. The dual layer coating improves the selectivity of the membrane support and maintains the membrane performance with time. The dual layer-coated membranes are suitable for a variety of liquid, gas, and vapor separations such as water purification, non-aqueous liquid separation such as deep desulfurization of gasoline and diesel fuels, ethanol/water separations, pervaporation dehydration of aqueous/organic mixtures, fuel gas conditioning, CO2/CH4, He/CH4, CO2/N2, H2/CH4, O2/N2, olefin/paraffin, iso/normal paraffins separations, and other light gas mixture separations. The dual layer-coated membranes are especially useful for natural gas liquid (NGL) recovery and CO2 removal from natural gas.

Abstract: A multi-stage membrane system is provided to separate helium from a gas stream such as a natural gas stream. There are at least two permeate streams from a first membrane module. One of the permeate streams is compressed and sent to a second membrane module while one of the permeate streams bypasses the compressor. There are control means provided to determine the flow for these two permeate streams based on factors including the compressor capacity, the concentration of the target component in the combined permeate streams and the capacity of the second membrane module.

Abstract: Embodiments of a process for discharging amine byproducts formed in an amine-based solvent are provided. The process comprises the steps of contacting the amine-based solvent with flue gas comprising carbon dioxide, oxygen, nitrogen, NOx, SOx, or mixtures thereof to form a carbon dioxide-laden amine-based solvent that contains the amine byproducts. Carbon dioxide is separated from the carbon dioxide-laden amine-based solvent to form a carbon dioxide-depleted amine-based solvent. The amine byproducts from the carbon dioxide-depleted amine-based solvent are fed to an algae source.
Abstract translation: 提供了在胺系溶剂中形成的胺副产物的排出方法的实施方式。 该方法包括以下步骤：使胺基溶剂与包含二氧化碳，氧气，氮气，NOx，SO x或其混合物的烟气接触，以形成含有胺副产物的含二氧化碳的胺基溶剂。 将二氧化碳与载有二氧化碳的胺类溶剂分离以形成不含二氧化碳的胺类溶剂。 将来自二氧化碳贫化胺基溶剂的胺副产物进料至藻源。

Abstract: Adsorption vessels and systems utilizing adsorption vessels are provided herein. In one embodiment, an adsorption vessel for receiving a fluid mixture and for separating a component from therein includes a vessel wall extending from a bottom end to a top end and defining a vessel chamber. A bottom inlet is formed in the bottom end of the adsorption vessel for introducing the fluid mixture to the vessel chamber. A filler material having a total porosity of less than about 25% and a density less than about 900 kg/m3 or an insert or both are positioned in the top void volume to increase overall performance of the adsorbent vessel.
