    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 translation: 该方法包括使用来自含有C 11至C 14烃的油馏分馏分的前端的特定选择的焦炭前体化合物及其作为催化重整器中石脑油加工中的添加剂的用途。 C11至C14化合物添加剂将连续催化再生（CCR）重整器中的焦炭提高到通常在低焦碳石脑油重整操作中生产的水平。 随着汽油中乙醇混合的增加和重整油辛烷值的降低，改性剂不会产生必要量的焦炭，以维持稳态白烧操作。

    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。

    Abstract: This instrumental method requires no sample preparation to determine not only whether a fuel contains DRA, but also the manufacturer(s) of the DRA. To date, there is no available method to quickly and easily perform this analysis. Only 60 microliters of sample are needed for the determination, which can be performed within two hours.

    Abstract: Systems and methods for injecting hydrogen into a natural gas pipeline to lower the carbon intensity of the resulting fuel blend while achieving the required energy output thereof for the end user. In one embodiment a blend ratio for the blended fuel comprising hydrogen and natural gas is determined based at least in part on a minimum energy output for fuel combusted at an end-use location connected to the natural gas pipeline so that the blended fuel (i) has a lower carbon intensity than a natural gas stream flowing in the natural gas pipeline, and (ii) provides at least the minimum energy output when combusted at the end-use location. Further, one or more embodiments include adjusting a control valve of a hydrogen injection assembly connected to the natural gas pipeline upstream of the end-use location based at least in part on the blend ratio to thereby mix hydrogen into the natural gas pipeline and produce the blended fuel.

    Abstract: Embodiments of systems and methods to determine vegetation migration encroachment along a right-of-way associated with an underground feature are disclosed. In an embodiment, the method may include capturing images of one or more sections of the right-of-way at a selected time period. The method may include georeferencing the images to correlate the images with a surface of a geographical location of the right-of-way. The method may include determining and clipping an area of interest for the images. The method may include tiling clipped images to a preselected size to define a plurality of tiled clipped images. The method may include determining a vegetation migration encroachment onto the right-of-way by application of the clipped images to the trained machine learning model. The method may include, in response to a determination that the vegetation migration encroachment exceeds a threshold, generating an indication of vegetation migration encroachment.
