  • Publication number: 20240228889
    Abstract: A process, a process plant and equipment for conversion of a feedstock rich in oxygenates to a hydrocarbon including directing the feedstock in combination with a recycle gas stream to a hydroprocessing step, to provide a two-phase hydroprocessed process stream including at least hydrogen, methane and hydrocarbons, combining a methane lean stream of hydrocarbons being liquid at ambient temperature, with a methane donor stream being either (i) the two-phase hydroprocessed process stream including methane or (ii) a gaseous stream derived from the two-phase hydroprocessed process stream by phase separation, to provide a multiple-phase combined stream, separating the multiple-phase combined stream into at least a hydrogen rich gas stream and a rich liquid hydrocarbon stream, in a desorption step desorbing an amount of methane from the rich liquid hydrocarbon stream, to provide a methane rich gas phase and a liquid product stream of hydrocarbons.

  • Patent number: 11279893
    Abstract: In a method for the hydroprocessing of renewable feeds in a hydroprocessing unit (unit A), comprising the use of sour waste water from the same or another unit (unit B), which is processing feeds containing sulfur and nitrogen, as wash water in unit A, thereby changing the pH of the waste water from unit A to lower the risk of carbonic acid corrosion of corrodible steel parts in unit A, the renewable material in unit A is directed to contact a material that is catalytically active in hydrogenating the renewable material in the presence of hydrogen, and the effluent is combined with the wash water stream which contains hydrogen sulfide and/or ammonia.

  • Patent number: 7674439
    Abstract: A quench zone mixing apparatus that occupies a low vertical height and has an improved mixing efficiency and fluid distribution across the catalyst surface includes a swirl chamber, a rough distribution network, and a distribution apparatus. In the swirl chamber, reactant fluid from a catalyst bed above is thoroughly mixed with a quench fluid by a swirling action. The mixed fluids exit the swirl chamber through an aperture to the rough distribution system where the fluids are radially distributed outward across the vessel to the distribution apparatus. The distribution apparatus includes a plate with a number of bubble caps and associated drip trays that multiply the liquid drip stream from the bubble caps to further symmetrically distribute the fluids across the catalyst surface. Alternatively, deflector baffles may be associated with the bubble caps to provide a wider and more uniform liquid distribution below the plate.

  • Patent number: 7125006
    Abstract: A bubble cap (100) has a riser (120) and a cap (130), separated by a divider (140) that extends to a length at least 50% of a distance measured between the top of the riser (122) and the bottom of the cap (134). In another aspect, the riser (120) and cap (130) cooperate to provide a skirt height (160) of no less than 1.5?. More preferred bubble caps (400) have a relatively high skirt height (460) or long slit length (497), or both.

  • Patent number: 6881387
    Abstract: A quench zone mixing apparatus (16) that occupies a low vertical height and has an improved mixing efficiency and fluid distribution across the catalyst surface includes a swirl chamber (20), a rough distribution network (100), and a distribution apparatus (120). In the swirl chamber (20), reactant fluid from a catalyst bed above is thoroughly mixed with a quench fluid by a swirling action. The mixed fluids exit the swirl chamber (20) through an aperture to the rough distribution system (100) where the fluids are radially distributed outward across the vessel to the distribution apparatus (120). The distribution apparatus (120) includes a plate (122) with a number of bubble caps (130) and associated a drip trace (150) that multiply the liquid drip stream from the bubble caps (130) to further symmetrically distribute the fluids across the catalyst surface. Alternatively, deflector baffles may be associated with the bubble caps (130) to provide a wider and more uniform liquid distribution below the plate (122).

  • Patent number: 6508459
    Abstract: The invention is directed to a bubble cap including: a riser having a lower end located within and extending through an aperture in the plate of the distribution apparatus and a top end to define a passageway between the ends; a cap located over the top end of the riser, the cap having a top portion and a downwardly extending skirt portion; at least one spacer located between the riser and the cap to maintain a gap between the top end of the riser and the cap; and a plurality of riser vanes located between the top end of the riser and the top portion of the cap. An annulus (“bubble cap annulus”) is created between the riser and the cap. The riser vanes are preferably flush against the underside of the bubble cap top wall. The riser vanes are spaced from each other to form vane passageways. Preferably, the vane passageways are the only (or sole) means of fluid communication between the bubble cap annulus and the riser passageway.

  • Patent number: 6338828
    Abstract: A quench zone mixing apparatus is supported within a vessel of a reactor by a support structure that includes a concentric hub, which may be formed to act as a torsion tube, and at least a first set of radial beams extending radially outward from the hub and terminating at a support ring that is attached to the reactor vessel wall. In particular, the radial beams comprise a flange that supports the redistribution tray and a web of the beams preferably includes a plurality of openings to allow the passage of fluids across the vessel. In addition, the webs also carry the channels. The radial beams also support the mixing chamber and, in the area between the wall of the mixing chamber and the vessel wall, the radial beams may have a vertical height that slopes downward from the vessel wall to the mixing chamber wall.
