This invention relates to a dispersion comprising porous particles dispersed in a liquid phase, wherein the porous particles comprise a zeolite and the liquid phase is a size-excluded liquid. The invention also relates to a method of adsorbing a gas into a liquid, comprising at least the step of bringing the gas into contact with the dispersion. In addition, the invention relates to an assemblage of the dispersion, the zeolite comprising a cavity and a gas contained within the cavity.

The present disclosure provides compositions and methods that are useful in removing, lowering the amount of, or otherwise controlling hydrogen sulfide and mercaptans. The compositions and methods can be used in any industry where hydrogen sulfide poses problems, such as when dealing with crude oil based, natural gas based, and/or coal based products. The present disclosure provides compositions and methods that can reduce the amount of or eliminate hydrogen sulfide in a variety of mediums.

A process is provided for making a polymer comprising providing a mixture of at least one furandicarboxylic acid, at least one diol, and at least one C2-C3 dicarboxlic acid, ester derivatives of C2-C3 dicarboxylic acid, hydroxy fatty acid or ester derivative of a hydroxy fatty acid; adding a catalyst and processing said mixture at reaction conditions until a polymer product is produced. The polymer consists of random units based upon the starting materials that are used.

A hydrophilized material has a surface provided with surface roughness that arithmetic mean roughness is 0.3 μm to 1.0 μm and mean width of roughness profile elements is 0.1 mm or less. A hydrophilized member that contacts a liquid is at least partially made of the hydrophilized material. The hydrophilized member is applicable to a gas-liquid contact apparatus having a gas-liquid contact section, a liquid supply system, and a gas supply system, to constitute the gas-liquid contact section as a packing element. Wettability imparted due to the surface roughness is exhibited continuously.

Disclosed is a process for regenerating a hybrid solvent used to remove contaminants from a fluid stream and to provide an improved yield of purified fluid. Said process comprises a purification unit (12) and at least one regeneration unit (40) wherein make-up water (72) is added to the regenerated lean hybrid solvent (55) prior to reuse in the first purification unit and no water is recycled into the regeneration unit.

Disclosed is a process for regenerating a hybrid solvent used to remove contaminants from a fluid stream and to provide an improved yield of purified fluid. Said process comprises at least one purification unit (12) and at least one regeneration unit (40) wherein condensed water 62 from the regeneration unit is recycled back into the purification unit and none of the condensed water is reintroduced into the regeneration unit.

A system for processing a gas stream can include a physical solvent unit, an acid gas removal unit upstream or downstream of the physical solvent unit, and an LNG liquefaction unit downstream of the acid gas removal unit. The physical solvent unit is configured to receive a feed gas, remove at least a portion of any C.sub.5+ hydrocarbons in the feed gas stream using a physical solvent, and produce a cleaned gas stream comprising the feed gas stream with the portion of the C.sub.5+ hydrocarbons removed. The acid gas removal unit is configured to receive the cleaned gas stream, remove at least a portion of any acid gases present in the cleaned gas stream, and produce a treated gas stream. The LNG liquefaction unit is configured to receive the treated gas stream and liquefy at least a portion of the hydrocarbons in the treated gas stream.

Methods of reducing acid gas from a stream, comprising contacting the stream with a solvent system comprising a glycerol derivative are described herein. Disclosed herein is a composition comprising a glycerol derivative and an acid gas. A method for sweetening a natural gas stream comprising contacting a solvent system comprising a glycerol derivative with a natural gas stream is described herein.

Disclosed is a process for regenerating a hybrid solvent used to remove contaminants from a fluid stream and to provide an improved yield of purified fluid. Said process comprises at least one purification unit (12) and at least one regeneration unit (40) wherein condensed water (72) from the regeneration unit is combined with the regenerated lean hybrid solvent (55) prior to reuse in the purification unit and none of the condensed water is recycled into the regeneration unit.

Disclosed is a process for regenerating a hybrid solvent used to remove contaminants from a fluid stream and to provide an improved yield of purified fluid. Said process comprises at least two purification units and at least one regeneration unit wherein regenerated lean hybrid solvent and condensed water from the regeneration unit is used to reclaim additional purified fluid in the second purification unit.
