Abstract: Systems and methods are disclosed for enhancing the processing of hydrocarbons in a FCC unit by introduction of fluidized plastic at one or more locations of the FCC unit. In an embodiment, the method may include passing a coked FCC catalyst from a cyclone of the FCC unit to a regenerator. The method may include introducing at least oxygen and a fluidized plastic into the regenerator. The method may include combusting a combination of the fluidized plastic and a coke from the coked FCC catalyst in the regenerator, thereby to oxidize via the oxygen and produce a regenerated FCC catalyst and a flue gas. The method may include supplying the regenerated FCC catalyst from the regenerator to a riser of the FCC unit to crack the gas oil supplied to the riser of the FCC unit.

Abstract: Systems and methods for a vent interlock system to ensure vent cover closure prior to operation of a transportation vehicle. An embodiment of a system may include an interlock bar. The interlock bar may, in a lowered position, prevent a hydraulic valve handle of a hydraulic pump assembly from moving from an open position to a closed position, the hydraulic valve handle in the closed position to allow a vent cover of the trailer to be opened. The system may include a plunger valve connected to brakes of the transportation vehicle to lock the brakes of the transportation vehicle to prevent operation of the transportation vehicle when the interlock bar is raised. The system may include a spring operated latch attached to the transportation vehicle to hold the interlock bar in the lowered position via a notch or aperture in the interlock bar.

Abstract: An embodiment of an exhaust handling system for a marine vessel includes a cap connected to a top end portion of an exhaust stack of the marine vessel to form an enclosure at least partially surrounding an outlet of an exhaust pipe extending through the exhaust stack. In addition, the exhaust handling system includes a collection pipe in fluid communication with the cap such that the collection pipe is to receive exhaust from the enclosure, and a coupling connected to the collection pipe that is to connect to an exhaust cleaning assembly. The exhaust cleaning system includes a tank to receive the exhaust. The cap at least partially defines a first flow path for the exhaust that extends from the enclosure to the atmosphere. The collection pipe at least partially defines a second flow path for the exhaust that extends from the enclosure to the coupling via the collection pipe.

Abstract: Systems and methods for insulating vessels are disclosed. In one or more embodiments, the disclosure provides a vessel insulation system (e.g., for use with a reactor or pressure vessel), which includes a floating ring sized to circumscribe a top nozzle of a vessel; a plurality of straps connected to the floating ring, the plurality of straps extending downward from the floating ring and being positioned to run along a length of the outer shell of the vessel; and a plurality of segmented rings positioned to circumscribe the outer shell of the vessel and connected to the plurality of straps. The plurality of segmented rings is configured to support an insulation material circumscribing the outer shell of the vessel, which can provide effective securement of the insulation material around the outer shell without welding components on the vessel to secure the insulation material.

Abstract: Methods and systems for reducing NOx in a heat generation unit are provided. A method includes introducing an exhaust gas from a catalytic cracking unit to a combustion zone of a heat generation unit to produce a combusted exhaust gas, wherein the exhaust gas contains two or more of carbon monoxide, hydrogen cyanide, ammonia, and nitrogen oxide. The method further includes introducing a sour water stripper (SWS) vapor stream from a SWS unit to the heat generation unit at a location after the combustion zone and before a heat recovery zone of the heat generation unit. The method also includes allowing the SWS vapor stream to react with the combusted exhaust gas to produce a processed exhaust gas with decreased NOx content as compared to the NOx content when the exhaust gas is processed under similar conditions but without an interaction with the SWS vapor stream.

Abstract: Low sulfur fuel oil blend compositions and methods of making such blend compositions to increase the stability and compatibility of LSFO blends having paraffinic resids that are blended with distillates and/or cracked stocks of higher asphaltenes and/or aromatics content. In one or more embodiments, distillates and/or cracked stocks that incrementally reduce the initial aromaticity of the distillate or cracked stock with the highest aromaticity are sequentially blended prior to resid addition. Such incremental reduction and sequential blending have been found to provide a resulting low sulfur fuel oil blend that is both compatible and stable.

Abstract: Assemblies and methods to enhance hydrotreating and fluid catalytic cracking (FCC) processes associated with a refining operation, during the processes, may include supplying a hydrocarbon feedstock to a cat feed hydrotreater (CFH) processing unit to produce CFH unit materials. The assemblies and methods also may include conditioning material samples, and analyzing the samples via one or more spectroscopic analyzers. The assemblies and methods further may include prescriptively controlling, via one or more FCC process controllers, based at least in part on the material properties, a FCC processing assembly, so that the prescriptively controlling results in causing the processes to produce CFH materials, intermediate materials, the unit materials, and/or the downstream materials having properties within selected ranges of target properties, thereby to cause the processes to achieve material outputs that more accurately and responsively converge on one or more of the target properties.

Abstract: Assemblies and methods for monitoring the cathodic protection of underground or submerged structures may include a coupon assembly including a conductive test coupon and a reference electrode for determining the voltage potential difference of the protected structure without substantially interrupting surrounding current sources. The reference electrode may be at least partially covered with an electrolytic material in electrical contact with the surrounding environment via a plug including a porous material. A method of installation of the assembly may allow a single technician to install the coupon assembly using a probe rod without extensive on-site excavation. The coupon assembly may be configured to seat securely with the probe rod for stability during installation, and release from the probe rob when the probe rod is separated from the coupon assembly and withdrawn from the ground, leaving the coupon assembly at a preselected depth or preselected distance from the protected structure.

Abstract: Methods and assemblies may be used for determining and using standardized spectral responses for calibration of spectroscopic analyzers. The methods and assemblies may be used to calibrate or recalibrate a spectroscopic analyzer when the spectroscopic analyzer changes from a first state to a second state, the second state being defined as a period of time after a change to the spectroscopic analyzer causing a need to calibrate or recalibrate the spectroscopic analyzer. The calibration or recalibration may result in the spectroscopic analyzer outputting a standardized spectrum, such that the spectroscopic analyzer outputs a corrected material spectrum for an analyzed material, and defining the standardized spectrum. The corrected material spectrum may include signals indicative of material properties of an analyzed material, the material properties of the material being substantially consistent with material properties of the material output by the spectroscopic analyzer in the first state.

Abstract: An embodiment of an electrode watering assembly includes a cap having a cap body with a reservoir adjacent to a proximal electrode end of a permanent reference electrode when installed thereon. The cap body may include (i) a distal cap end defining a distal opening configured to be disposed around the proximal electrode end, (ii) a proximal cap end defining a proximal opening, and (iii) an outer wall defining an overflow port therethrough to receive overflow fluid from the reservoir and direct the overflow fluid out of the reservoir. The electrode watering assembly may include a conduit having a distal conduit end configured to be fluidly coupled to the proximal opening and a proximal conduit end configured to be positioned at a cathodic test station. Thus, fluid directed into the proximal conduit end is directed through the conduit and into the reservoir for watering at least the proximal electrode end.
