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： The present invention discloses a catalyst and process for hydrocracking of heavy hydrocarbon oils having majority portion boiling above 525° C. in the presence of hydrogen. A process comprising first step of converting heavy oil into lighter products in the presence of catalyst and hydrogen in slurry phase is disclosed. The process further comprises recycling of part of liquid products (HVGO) along with fresh heavy oil for improving the product selectivity. This recycled HVGO is having high concentrations of aromatics compounds. The separation of particles generated during the reaction at reactor exit also avoids the chances of choking of downstream sections.

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.
