Abstract: Systems and methods are provided for improving the operation of groups of reverse flow reactors by operating reactors in a regeneration portion of the reaction cycle to have improved flue gas management. The flue gas from reactor(s) at a later portion of the regeneration step can be selectively used for recycle back to the reactors as a diluent/heat transport fluid. The flue gas from a reactor earlier in a regeneration step can be preferentially used as the gas vented from the system to maintain the desired volume of gas within the system. This results in preferential use of higher temperature flue gas for recycle and lower temperature flue gas for venting from the system. This improved use of flue gas within a reaction system including reverse flow reactors can allow for improved reaction performance while reducing or minimizing heat losses during the regeneration portion of the reaction cycle.

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: Techniques described herein relate to a method for identifying downhole conditions during a drilling operation using a vibratory separator. The method includes calibrating a sensor system attached to the vibratory separator by periodically measuring the G-force acting on the vibratory separator functioning under steady-state operating parameters. The method also includes determining the relationship between the G-force acting on the vibratory separator and the flow rate and rate of penetration (ROP) for the drilling operation by measuring the G-force acting on the vibratory separator functioning under different non-steady-state operating parameters. The method further includes determining an expected total basket weight for each G-force measurement using the G-force/flow rate/ROP relationship, monitoring a current total basket weight of the vibratory separator functioning under current operating parameters, and identifying a downhole condition if the current total basket weight is greater or less than the expected total basket weight for the current operating parameters.

Abstract: Lost circulation particles are commonly used in drilling and/or cementing operations to prevent fluid loss to a subterranean formation. Lost circulation fluids and methods of drilling and/or cementing operations may also use petroleum coke lost circulation particles composed of fluid coke and/or flexicoke material. Such petroleum coke lost circulation particles may have improved transport into wellbores because of their lower density compared to traditional lost circulation material and may produce fewer fines that can interfere with lost circulation efficacy.

Abstract: Detection and sampling of dissolved hydrocarbons of interest in an environment expected to have hydrocarbon molecules, such as a water column or interstitial water in sediment. An apparatus comprising at least one oleophilic film frame is deployed into the environment and the at least one oleophilic film frame is exposed thereto for a defined period of time, and thereafter isolated from the environment to cease exposure thereto. Hydrocarbon molecules scavenged by the oleophilic film may be analyzed to determine their type and/or concentration.

Abstract: A method of producing bifunctional catalyst systems that include a carbon-coated metal catalyst may comprise: coating a metal catalyst particle with a carbon-containing small molecule to produce a coated metal catalyst particle; carbonizing the carbon-containing small molecule on the coated metal catalyst particle to produce a carbon-coated metal catalyst particle; and mixing the carbon-coated metal catalyst particle with an acid catalyst particle to produce an acid/metal bifunctional catalyst system. Further, a method of producing bifunctional catalyst systems that include a carbon-coated acid catalyst may be similarly performed by coating a metal catalyst particle with a carbon-containing small molecule to produce a coated metal catalyst particle; carbonizing the carbon-containing small molecule on the coated metal catalyst particle to produce a carbon-coated metal catalyst particle; and mixing the carbon-coated metal catalyst particle with an acid catalyst particle to produce an acid/metal bifunctional catalyst system.
