    Abstract: Methods and systems of operating a pump at an efficiency point during an in-line blending operation. In an embodiment, such a method may include transporting a fluid from a tank to a pump through a first pipe. The method may include discharging, via the pump, the fluid at a specified flow rate through a second pipe. The method may include measuring a flow rate of the first portion of the fluid flowing from the main control valve through the mixing pipe. The method may include measuring a flow rate of the second portion of the fluid flowing through the spillback loop. The method may include determining a current pump efficiency point and operating the pump within a range of percentages of the best efficiency point.

    Abstract: Embodiments of systems and methods to determine depth of soil coverage for an underground feature along a right-of-way are disclosed. In an embodiment, the method may include receiving a depth of cover measurement for the right-of-way. The method may include capturing baseline images of the right-of-way within a first selected time of the depth of cover measurement. The method may include rendering a three dimensional elevation model of the right-of-way from the baseline images. The method may include georeferencing the three dimensional elevation model to generate a georeferenced three dimensional elevation model. The method may include adding the depth of cover measurement to the georeferenced three dimensional elevation model. The method may include rendering an updated three dimensional elevation model of the right-of-way from subsequently captured images. The method may include determining a delta depth of coverage based on the georeferenced and the updated three dimensional elevation model.

    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: 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.
