    Abstract: Scalable greenhouse gas capture systems and methods to allow a user to off-load exhaust captured in an on-board vehicle exhaust capture device and to allow for a delivery vehicle or other transportation mechanism to obtain and transport the exhaust. The systems and methods may involve one or more exhaust pumps, each with an exhaust nozzle corresponding to a vehicle exhaust port. Upon engagement with the vehicle exhaust port, the exhaust nozzle may create an air-tight seal between the exhaust nozzle and the vehicle exhaust port. A first pipe may be configured to transport captured exhaust therethrough from the exhaust nozzle to. The captured exhaust may be at least temporarily stored in an exhaust holding tank connected to and in fluid communication with the first pipe

    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during installation, and release from the probe rob when the probe rod is separated from the coupon assembly and withdrawn from the ground, leaving the coupon assembly at a preselected depth or preselected distance from the protected structure.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 systems of admixing hydrocarbon liquids from two or more sets of tanks into a single pipeline to provide in-line mixing thereof. In an embodiment of the in-line mixing system, hydrocarbon liquids stored in at least one tank of each of two or more sets of tanks positioned at a tank farm are blended into a blend flow pipe via in-line mixing and the blended mixture is pumped through a single pipeline. In one or more embodiments, the in-line mixing system employs a separate spillback or recirculation loop that is fluidly connected to each set of the two or more sets of tanks to control the flow of the hydrocarbon fluid/liquid from each set of tanks to the blend flow pipe. Associated methods of operating one or more embodiments of the system include regulation of spillback or recirculation loop flow rate and/or pressure to drive the actual blend ratio towards a desired blend ratio.

    Abstract: Embodiments include systems and methods of in-line mixing of hydrocarbon liquids from a plurality of tanks into a single pipeline. According to an embodiment, a method of admixing hydrocarbon liquids from a plurality of tanks into a single pipeline to provide in-line mixing thereof includes determining a ratio of a second fluid flow to a first fluid flow based on signals received from a tank flow meter in fluid communication with the second fluid flow and a booster flow meter in fluid communication with a blended fluid flow. The blended fluid flow includes a blended flow of the first fluid flow and the second fluid flow. The method further includes comparing the determined ratio to a pre-selected set point ratio thereby to determine a modified flow of the second fluid flow to drive the ratio toward the pre-selected set point ratio. The method further includes controlling a variable speed drive connected to a pump thereby to control the second fluid flow through the pump based on the determined modified flow, the pump being in fluid communication with the second fluid flow.

    Abstract: This development proposed adding a catalyst to an oxygen stripper. The oxygen stripper would be run at a temperature just below or at coking temp. The oxygen stripper includes a catalyst containing Group VI or VII metals to remove free radicals. Most preferably, the catalyst is a nickel-molybdenum catalyst.

    Abstract: This patent application discloses engineering design modifications to the VSS exit, stripper entrance and the primary cyclone diplegs that can significantly reduce the underflow of reactor riser products into the stripper and reactor vessel and thereby produce higher desired product selectivities, improved stripping efficiency and a stripper vent gas, that continuously flows through the reactor vessel, with a low coke forming potential due to its low concentration of ethylene and higher molecular weight material, that could, if desired, be recovered separately from the primary riser products.
