Abstract: This disclosure relates to the adsorption and separation of fluid components, such as oxygen, in a feed stream, such as air, using zeolite ITQ-55 as the adsorbent. A process is disclosed for adsorbing oxygen from a feed stream containing oxygen, nitrogen and argon. The process comprises passing the feed stream through a bed of an adsorbent comprising zeolite ITQ-55 to adsorb oxygen from the feed stream, carrying out an equalization step to improve recovery, thereby producing a nitrogen product stream depleted in oxygen as well as a waste stream can be collected to have enriched oxygen. The kinetic selectivity and related mass transfer rates can be tuned by varying the mean crystal particle size of zeolite ITQ-55 within the range of from about 0.1 microns to about 40 microns, or by varying the adsorption temperature within the range from about -195° C. to about 30° C., or by varying the adsorption pressure within the range from about 1 bar (~14.7 psi) to about 30 bar (~435 psi), or combinations thereof. The feed stream is exposed to the zeolite ITQ-55 at effective conditions for performing a rapid cycle of kinetic separation, in which oxygen exhibits greater kinetic selectivity than nitrogen and argon.

Abstract: A method of predicting hydrocarbon production from one or more artificial lift wells is disclosed. Measurements and/or well test data are obtained from one or more artificial lift wells representing well performance at more than one time period. A statistical model, representing well performance, is generated. Using the statistical model and the measurements and/or well test data, real-time production of the one or more artificial lift wells is predicted and a measure of confidence is generated. Potential optimization opportunities are identified for well performance based on the predicted real-time production of the one or more artificial lift wells. The optimization opportunities are outputted. Hydrocarbon production activities are modified using the optimization opportunities.

Abstract: Systems and methods are provided for conversion of a combined feed of oxygenates (such as methanol or dimethyl ether) and olefins to a high octane naphtha boiling range product with a reduced or minimized aromatics content. The oxygenate conversion can be performed under conditions that reduce or minimize hydrogen transfer. Optionally, a catalyst that further facilitates formation of branched paraffins can be used, such as a catalyst that has some type of 12-member ring site available on the catalyst surface.

Abstract: Methods of producing metal catalysts can include mixing two or more metal salts and an aluminum salt in water to produce a metal catalyst precursor solution; mixing the metal catalyst precursor solution and an alkali metal buffer solution to produce a precipitate; ion exchanging the alkali metal in the precipitate for a non-alkali cation to produce a low-alkali metal precipitate comprising 3 wt % or less alkali metal by weight of the precipitate on a dry basis; producing a powder from the low-alkali metal precipitate; and calcining the powder to produce a metal catalyst. Such metal catalysts may be useful in producing bifunctional catalyst systems that are useful in, among other things, converting syngas to dimethyl ether in a single reactor.

Abstract: Systems and processes are provided for measuring carbon deposits on an engine. In some examples, a light source can be transmitted through a viewing window of an engine onto an area of an internal surface of the engine and reflected back through the viewing window and detected using an optical sensor. A topography of the area can be determined based, at least in part, on the reflected light source detected by the optical sensor and used to determine whether carbon deposits have increased, decreased, or remained constant on the area.

Abstract: A collection of compressible particles. The compressible particles are intended to be used for attenuating pressure build-up within a confined volume such as a trapped annulus in a wellbore. Each of the compressible particles is fabricated to collapse in response to fluid pressure within the confined volume, and comprises carbon. Particularly, each of the particles comprises a plurality of peripheral openings, permitting an ingress of wellbore fluids in response to an increase in pressure within a trapped annulus. The collection of compressible particles together has a reversible volumetric expansion/contraction of ≥10% and up to 25% at pressures up to 10,000 psi. A method of attenuating annular pressure buildup within a wellbore using the collection of compressible particles is also provided.

Abstract: A method for liquefying a feed gas stream. A refrigerant stream is cooled and expanded to produce an expanded, cooled refrigerant stream. Part or all of the expanded, cooled refrigerant stream is mixed with a make-up refrigerant stream in a separator, thereby condensing heavy hydrocarbon components from the make-up refrigerant stream and forming a gaseous expanded, cooled refrigerant stream. The gaseous expanded, cooled refrigerant stream passes through a heat exchanger zone to form a warm refrigerant stream. The feed gas stream is passed through the heat exchanger zone to cool at least part of the feed gas stream by indirect heat exchange with the expanded, cooled refrigerant stream, thereby forming a liquefied gas stream. The warm refrigerant stream is compressed to produce the compressed refrigerant stream.
