A hydrophobic MOF-based porous liquid carbon capture absorbent is provided and includes a sterically hindered solvent and a hydrophobic MOFs modified material dispersed in the sterically hindered solvent. A mass percent of the hydrophobic MOFs modified material in the hydrophobic MOF-based porous liquid carbon capture absorbent is 5% to 20%. The hydrophobic MOFs modified material is prepared by a method comprising following steps: dispersing an MOFs material, a surface modifier and a catalyst in an organic solvent, and mixing them evenly, followed by a standing reaction to obtain the hydrophobic MOFs modified material.

A hydrogen generation and carbon capture system includes a fuel reformer, hydrogen purifier, fuel cell, three heat exchangers, two knockout drums, absorber, burner feed pressure regulator, burner, flash tank, solvent trim cooler, and condenser. A process for hydrogen generation and carbon capture includes pumping, heating, and reforming a fuel and water feed. The process includes extracting hydrogen from a raw syngas, directing hydrogen to a fuel cell, separating liquid from a cooled carbon monoxide and carbon dioxide rich syngas mixture and feeding this stream to an absorber. The process includes reducing pressure and burning the syngas mixture, heating the carbon dioxide rich solvent stream, and cooling the cooled regenerated solvent. The process includes heating the heated carbon dioxide rich solvent stream, separating carbon dioxide from the stream, condensing the carbon dioxide stream, and separating liquid from the gas/liquid mixture.

Disclosed in certain embodiments are processes for heavy hydrocarbon removal that implement a regeneration loop that introduces an absorbent into a regeneration gas stream, and systems for implementing the same.

The present invention relates to a method for upgrading biogas generated by a biological process wherein at least carbon dioxide is removed from the bio-gas. More specifically the present invention relates to method for upgrading a biogas comprising a first absorption step wherein the liquid effluent is subjected to a second absorption step and a flash step and the gas streams resulting therefrom are recycled. The present invention also relates a biogas upgrading plant.

The present disclosure relates to a porous liquid or a porous liquid enzyme system that includes a high surface area solid and a liquid film substantially covering the high surface area solid. The porous liquid or porous liquid enzyme may be contacted with a fluid that is immiscible with the liquid film such that a liquid-fluid interface is formed. The liquid film may facilitate mass transfer of a substance or substrate across the liquid-fluid interface. The present disclosure also provides methods of performing liquid-based extractions and enzymatic reactions utilizing the porous liquid or porous liquid enzyme of the present disclosure. The present disclosure also provides methods for selecting the components of the porous liquid or a porous liquid enzyme system and methods of self-replenishing the used liquid coating.

Systems and methods presented herein generally relate to recycling, or reducing flaring or venting, of vent gases from glycol based dehydration of natural gas. Some systems and methods use high pressure gas, high pressure glycol, or pump-assisted high pressure glycol to provide motive energy to draw reflux gas and/or skimmer gas through one or more venturis and back to the contact tower of the dehydration system. Some systems and methods provide for harvesting energy from the dehydration process.
