    摘要： An apparatus for supplying additives into a coker drum includes an inlet for supplying a hydrocarbon feed stream into the coker drum and conduits along the circumference of walls of the coker drum. Each conduit has an injection nozzle to supply additives inside the coker drum. An injection control system controls the operation of the injection nozzles such that 1) one or more of the injection nozzles placed within a first distance above a vapour liquid interphase of the hydrocarbon feed stream are configured to supply the additives; and 2) supply of the additive discontinues from a particular injection nozzle when a distance between the injection nozzle and the vapour liquid interphase is less than or equal to a second distance. The apparatus optionally includes a mechanical drive system moving at least one of the conduits based on the level of the vapour liquid interphase in the coker drum.

    摘要： A multi-stage hydrotreating process obtains ultra-low sulfur diesel boiling range hydrocarbon having less than 10 ppm sulfur with elimination of external hot high pressure separator and avoids the formation of recombinant mercaptans by removing excess hydrogen sulfide formed during hydroprocessing reaction. The process includes mixing a diesel boiling range hydrocarbon feedstock with hydrogen and sending to the first predominantly liquid phase hydroprocessing reaction stage. Effluent from the first hydroprocessing reaction stage is sent to first separator zone of open and empty space in the upper part of the second hydroprocessing reaction stage to flash off the dissolved reaction products hydrogen sulfide and ammonia. Liquid part of the effluent of first hydroprocessing reaction stage is passed to the second predominantly liquid phase hydroprocessing reaction stage. The process is repeated until the liquid product sulfur level of less than 10 ppm is attained and the liquid product is sent to further processing.

    摘要翻译： 多级加氢处理工艺获得具有小于10ppm硫的超低硫柴油沸程烃，消除外部热高压分离器并避免通过除去加氢处理反应中形成的过量硫化氢而形成重组硫醇。 该方法包括将柴油沸程烃原料与氢气混合并送至第一主​​要液相加氢处理反应阶段。 来自第一加氢处理反应阶段的流出物被送到第二加氢处理反应阶段上部的开放空闲空间的第一分离区，以使溶解的反应产物硫化氢和氨闪蒸。 第一加氢处理反应阶段的流出物的液体部分通过第二主要液相加氢处理反应阶段。 重复该过程，直到达到低于10ppm的液体产物硫含量并将液体产物送至进一步加工。
