Abstract: Provided herein are post-synthesis methods of thermally stabilizing a metal-organic framework having defects that decomposes after about 12 hours at a first temperature. The methods include contacting the metal-organic framework with a stabilizing solution to provide a treated metal-organic framework. The treated metal-organic framework is thermally stable after 12 hours at a second temperature at least about 50° C. greater than the first temperature. Also, the treated metal-organic framework has a PXRD pattern that is substantially the same as the PXRD pattern of the untreated metal-organic framework. Provided herein are also post-synthesis methods to improve CO2 adsorption of metal-organic frameworks. Provided herein are also modified EMM-71 metal-organic frameworks.

Abstract: A methodology for estimating stresses in the subsurface for the generation of a three dimensional (3D) mechanical earth model is provided. The method is executed via a processor of a computing system. The method includes generating a synthetic principal horizontal stress profile representative of a one-dimensional mechanical earth model (1D MEM) based on simplification that all formations are elastically isotropic. The method also includes combining the isotropically generated synthetic principal horizontal stress profile with an additional data-driven functional relationship for anisotropic formations to generate a global predictive conditional relationship based on a lithology dependent cutoff. The method also further includes generating a three-dimensional volume-based mechanical earth model using the global predictive conditional relationship.

Abstract: Improved processes and systems for removing CO2 from exhaust gas to substantially prevent such greenhouse gas from being released to the atmosphere. The systems and processes use a) staged cooling of an exhaust gas stream, b) addition of an antifreeze, and c) a combination of non-scraped heat exchangers and scraped heat exchangers to separate CO2 from an exhaust stream while reducing or minimizing accumulation of ice on surfaces within the system.

Abstract: Systems and methods are provided for separation of particles and/or asphaltenes from heavy hydrocarbon fractions. The heavy hydrocarbon fraction can correspond to a feed including particles or a processing effluent that includes particles. If the heavy hydrocarbon fraction is mixed with lower boiling fractions, a separation can be performed to reduce or minimize the amount of hydrocarbons that are present in the heavy hydrocarbon fraction. The heavy hydrocarbon fraction can then be mixed with a sufficient amount of a separation solvent to cause a phase separation. One phase can correspond to the separation solvent plus a portion of the hydrocarbons. The other phase can correspond to hydrocarbons rejected by the separation solvent plus the particles from the heavy hydrocarbon fraction. The phases can then be separated from each other using a solids-liquid centrifugal separator.

Abstract: A process for selectively separating H2S from a gas mixture which also comprises CO2 is disclosed. A stream of the gas mixture is contacted with an absorbent solution comprising one or more amines, alkanolamines, hindered alkanolamines, capped alkanolamines, or mixtures thereof. The H2S/CO2 selectivity of the absorbent solution is preferably greater than about 4.0 for an acid gas loading [mol(CO2+H2S)/mol(amine)] between about 0.2 and about 0.6, and is achieved by reducing pH of the absorbent solution.

Abstract: A methodology for extending bandwidth of geophysical data is disclosed. Geophysical data, obtained via a towed streamer, may have significant noise in a certain band (such as less than 4 Hz), rendering the data in the certain band unreliable. To remedy this, geophysical data, from a band that is reliable, may be extended to the certain band, resulting in bandwidth extension. One manner of bandwidth extension comprises using machine learning to generate a machine learning model. Specifically, because bandwidth may be viewed as a sequence, machine learning configured to identify sequences, such as recurrent neural networks, may be used to generate the machine learning model. In particular, machine learning may use a training dataset acquired via ocean bottom nodes in order to generate the machine learning model. After which, the machine learning model may be used to extend the bandwidth of a test dataset acquired via a towed streamer.

Abstract: A method and apparatus for producing liquefied natural gas (LNG) from a natural gas stream. Heavy hydrocarbons are removed from the natural gas stream in a separator to generate a bottom stream and a separated natural gas stream, which is used as a coolant in a heat exchanger to generate a pretreated natural gas stream. The pretreated natural gas stream is compressed and cooled to form a chilled pretreated natural gas stream, part of which forms a recycle stream to exchange heat with the separated natural gas stream in the heat exchanger, thereby generating a cooled recycle stream. The temperature and pressure of the cooled recycle stream are reduced. The cooled recycle stream is then separated into an overhead stream and a reflux stream, which is directed to the separator. The chilled pretreated gas stream is liquefied to form LNG.
