  • Patent number: 10739798
    Abstract: Systems and methods are disclosed for detecting temperature excursion in a chemical plant or petrochemical plant or refinery. Aspects of the disclosure provide an enhanced control system for a reactor, such as in hydroprocessing. The enhanced control system may provide early warnings of impending undesirable events, directly or indirectly manipulate certain process variables to reduce undesirable outcomes, and/or directly or indirectly manipulate of certain process variables so as to place a reactor unit in a “safe park” state. This may avoid a high temperature trip, depressuration, associated operating risks, allow for faster recovery from temperature excursions, and/or avoid unplanned emergency shutdowns of the reactor, chemical process, plant, or refinery.

  • Patent number: 10710879
    Abstract: The process can be used in any hydrocarbon process in which it is desirable to recover hydrogen. The process can include catalytically reforming a hydrocarbon feed, a paraffin dehydrogenation to produce light olefins or a synthesis gas generating process. There is an effluent stream having hydrogen and hydrocarbons that is first sent to an adsorption zone to produce a pure hydrogen stream and a tail gas stream. The tail gas stream is then sent across a feed side of a membrane having the feed side and a permeate side. The membrane that is selected is selective for hydrogen over one or more C1-C6 hydrocarbons and light ends including CO, CO2, N2 and O2, and withdrawing from the permeate side a permeate stream enriched in hydrogen compared with a residue stream withdrawn from the feed side. The permeate stream is then recycled to be sent through the adsorption zone.

At least a portion of the stabilizer off-gas stream is contacted with a dried feed stream to remove chlorides from the stabilizer off-gas stream. The dried feed stream is not cooled before absorbing the chlorides. A portion of the dried feed stream may bypass the absorbing section. A chiller is disposed on top of the vessel with the absorbing section.

  • Patent number: 10703992
    Abstract: Settling unconverted pitch from a SHC reactor effluent before fractionation improves efficiency of fractionation of slurry hydrocracked products. The recycle of soft pitch to the SHC reactor results in improved reactor operation by avoiding the recycle of lighter products which vaporize in the reactor to occupy reactor space and the recycle of hard pitch which will not convert. The settling step facilitated by mixing with a solvent can achieve a separation between soft pitch and hard pitch not achievable in a fractionation column.

  • Patent number: 10702798
    Abstract: A process for treating an ionic liquid containing waste stream is described. If there is a liquid waste stream, the liquid waste stream is introduced into a liquid treatment zone. The ionic liquid in the liquid waste stream is neutralized. The concentration of the ionic liquid in the liquid waste stream is determined, and the allowed concentration of the ionic liquid in the liquid waste stream is determined. The concentration of the ionic liquid in the neutralized liquid waste stream is reduced to the allowed concentration, and the liquid waste stream having the allowed concentration is released. If there is a vapor waste stream, the vapor waste stream is introduced into a vapor treatment zone. The vapor waste stream is treated to form a treated vapor waste stream, and the treated vapor waste stream is released to a plant vapor treatment zone.
