  • Patent number: 10808176
    Abstract: The delayed coking method includes directing a heated secondary feedstock, which contains heated primary feedstock and recirculate, from a reaction furnace to a coking chamber. Vapor-liquid coking products formed in the coking chamber are then directed to a fractionation column, which fractionates hydrocarbon gas, gasoline, light and heavy gas oils, and bottom residues. Heavy gas oil from the fractionation column is directed to a thermal cracking furnace, the products of which are cooled by cooled light gas oil and directed to an evaporator for separation. In the evaporator, gases and light boiling products are removed by evaporation and returned to the fractionation column, and the remaining distillate cracking residue is separated and used as a component of the recirculate, along with bottom residues from the fractionation column. The resulting process produces high quality and high yield needle and anode cokes.

  • Patent number: 10800986
    Abstract: A paraffin control unit with staged high voltage temperature controlled electric immersion heaters to maintain the paraffin component of the crude oil in the liquid phase. The paraffin control unit removes large volumes of naturally occurring fine sand from the incoming liquids while also removing the crude oil from the influent fluid stream, the natural gas from the influent fluid stream, salt water from the influent fluid stream, all while maintaining the temperature of the crude oil fraction above the cloud point of its paraffin constituent. The removed sand is collected in sand pans and is automatically removed at timed intervals. The automation assures that the accumulating sand is removed from the sand pans as rapidly as it accumulates, thus preventing an over-accumulation of sand. The process fluids flow through a coalescer and a baffle assembly which purify and separate the component phases suitable for custody transfer.

  • Patent number: 10780430
    Abstract: Methods are provided for forming noble metal catalysts comprising both platinum and a second Group VIII metal, such as palladium, with improved aromatic saturation activity. Instead of impregnating a catalyst with both platinum and another Group VIII metal at the same time, a sequential impregnation can be used, with the Group VIII metal being impregnated prior to platinum. It has been discovered that by forming a Group VIII metal-impregnated catalyst first, and then impregnating with platinum, the distribution of platinum throughout the catalyst can be improved. The improved distribution of platinum can result in a catalyst with enhanced aromatic saturation activity relative to a catalyst with a similar composition formed by simultaneous impregnation.
