    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: The present invention defines six unexpected benefits resulting from the automation of and improvements to inventory reconciliation and tank level monitoring at tank farms, terminals and refineries, commonly associated with refining and the transportation of, hydrocarbon fuels. In the implementation of an automated system for tank level monitoring and periodic inventory reconciliation, it has been discovered that both applications can be used to correctly identify maintenance needs and policy violations that were previously unable to be identified. The benefits include identification of thermal relief valve failure, transmix check valve failure, lock out/tag out failure, floating roof landing, and incorrect tank assignments.

    Abstract: The delayed coking process comprises the steps of: thermally cracking hydrocarbon feedstock in the coke drum thereby converting the feedstock to coke and hydrocarbon products; routing thermally crack hydrocarbon products to downstream fractionators; and periodically removing coke out of the drum. Before coke removal, the drum has to be steam stripped, water quench, then vented. During venting, H2S scavenger is injected to the drum vapor space to remove residual H2S.

    Abstract: The process involves the use of specifically selected coke precursor compounds from the front end of oil distillate fractions that contain C11 to C14 hydrocarbons and their use as additives in the processing of naphtha in a catalytic reformer. The C11 to C14 compounds additives enhance coke make in continuous catalytic regeneration (CCR) reformers to levels higher than those which are usually produced in low coke naphtha reforming operations. With the increase of ethanol blending in gasoline and low reformate octane severity operations, reformers do not produce the necessary amount of coke to permit sustaining steady state white burn operations.

    Abstract: Optimizing low coke naphtha reforming continues to pose significant challenges for oil refining companies in the operation of continuous catalytic regenerative reforming units for economic production of hydrogen, LPG and reformate. A novel processing scheme is hereby disclosed wherein multiple additives are used to increase spent catalyst coke to ensure operating the regenerators in steady state white burn operations. In previous disclosures novel additives sulfur and kerosene were identified as separately imparting enhanced rates of coke formation on the catalysts even at very mild severity catalytic reforming operations. To further accelerate spent catalyst coke formation and derive benefits from synergistic use of sulfur and kerosene, it is suggested that both sulfur and kerosene be used as additives in combination or in series with sulfur added first followed by kerosene and vice versa.

    Abstract translation: 优化低焦碳氢化石改造对于炼油企业在经济生产氢气，液化石油气和重整产品的连续催化再生改质装置运行方面仍然构成重大挑战。 特此公开了一种新颖的处理方案，其中使用多种添加剂来增加废催化剂焦炭，以确保在稳态白烧操作中操作再生器。 在之前的公开内容中，添加剂硫和煤油被鉴定为分别赋予催化剂焦炭形成速率增加，即使在非常温和的严重性催化重整操作中也是如此。 为了进一步加速废催化剂焦炭形成，并从硫和煤油的协同使用中获益，建议将硫和煤油作为添加剂组合使用或与首先加入的硫串联使用，随后加入煤油，反之亦然。
