Abstract: Selective removal of non-aromatic hydrocarbons from a xylene isomerization process for para-xylene production is accomplished using a membrane unit positioned within a xylene recovery loop. The membrane unit may include a one-stage or multi-stage (e.g., two-stage) membrane system and may be configured to separate a membrane unit product stream from a non-aromatics rich stream, which can be removed from the xylene recovery loop. The membrane unit may have a xylene permeance of about 60 gm/m2/hr/psi and a xylene to non-aromatic permeance ratio of about 15.

Abstract: A method for producing a deposit resistant fluid includes combining a base stock and one or more additives to form a blended fluid configured to resist forming deposits in an oxidizing environment. The base stock has a viscosity index of at least 80, and either a kinematic viscosity at 40° C. of at least 320 cSt or a kinematic viscosity at 100° C. of at least 14 cSt. The base stock includes greater than or equal to about 90 wt % saturates, less than or equal to about 10 wt % aromatics, and a sum of terminal/pendant propyl groups and terminal/pendant ethyl groups of at least 1.7 per 100 carbon atoms.

Abstract: The present disclosure relates to methods and systems for sweetening natural gas may utilize a water wash to achieve a reduction in raw natural gas stream contaminants (e.g., particulate contaminants and/or chemical contaminants) and/or to recover solvent used for removing H2S and CO2 from the natural gas. For example, a method may include contacting a first natural gas stream with a first water stream in a co-current contacting system to produce a second natural gas stream and a second water stream, wherein the first natural gas stream comprises natural gas, an acid gas, and a contaminate, and wherein a concentration of the contaminate in the second natural gas stream is less than a concentration of the contaminate in the first natural gas stream; and removing at least a portion of the acid gas from the second natural gas stream.

Abstract: Methods and systems for hydrodeoxygenating a bio-derived feedstock during the production of renewable diesel and generating renewable power as part of the hydrodeoxygenation (HDO) process are provided herein. One method includes providing an HDO catalyst within either a shell or tube side of an isothermal HDO reactor including a shell-and-tube configuration and exposing a bio-derived feedstock to the HDO catalyst within the isothermal HDO reactor to form an HDO reactor effluent. The method also includes flowing a water stream through the opposite side of the isothermal HDO reactor as compared to the side including the HDO catalyst to remove the heat of reaction between the bio-derived feedstock and the HDO catalyst, where the removal of the heat of reaction using the water stream forms steam. The method further includes flowing the steam through a steam turbine to provide for the generation of renewable power.

Abstract: Solvent mixtures for downhole elemental sulfur removal and formation stimulation, and methods for utilizing such solvent mixtures, are described herein. One method includes providing a solvent mixture that includes an elemental sulfur solvent fraction and an odorant fraction that includes a lactate ester solvent. The method also includes injecting the solvent mixture into a hydrocarbon well such that the elemental sulfur solvent fraction of the solvent mixture dissolves elemental sulfur deposited on well components, and contacting the solvent mixture with water such that the lactate ester solvent within the odorant fraction reacts with the water to generate lactic acid. The method further includes stimulating a formation through which the hydrocarbon well extends by flowing the solvent mixture including the lactic acid through the hydrocarbon well and into the formation.

Abstract: This disclosure provides methods for separating multi-ring naphthenes from a hydrocarbon feedstock. The hydrocarbon feedstock includes at least normal paraffins, isoparaffins, 1-ring naphthenes attached with a paraffinic alkyl chain, and multi-ring naphthenes. The methods comprise passing the hydrocarbon feedstock and a solvent, at a temperature and pressure through a bed of an adsorbent comprising a metal-organic framework (MOF) adsorbent, to adsorb the multi-ring naphthenes from the hydrocarbon feedstock, thereby producing a base stock product that is depleted in multi-ring naphthenes. The metal-organic framework adsorbent is a porous crystalline material comprised of metal functionalities connected by organic linkers to form a repeating 2-D or 3-D lattice. The base stock product has a viscosity index (VI) greater than the viscosity index of the hydrocarbon feedstock. The methods of this disclosure upgrade Group II base stocks (also Group II+ base stocks) to Group III or Group III+ base stocks, and also upgrade Group III base stocks to Group III+ base stocks.
