  • Publication number: 20240218272
    Abstract: A process for dimerizing and oligomerizing olefins to distillate fuels which subjects oligomerized product to hydrocracking and perhaps hydroisomerization to convert heavier oligomers to jet fuel range oligomers. A jet fuel product stream may be taken from a side of a stripping column which produces a heavy drag stream from a bottom of the stripping column to ensure an end point boiling specification is achieved.

  • Publication number: 20240182801
    Abstract: An ethanol dehydration process is disclosed. The process comprises adding an amount of steam to a feed to the dehydration reactor to provide a charge stream. The steam stream is mixed with the feed to the dehydration reactor such that the steam to ethanol ratio is between about 0.5 to about 5.0 wt/wt. The charge stream is passed to a dehydration reactor to produce a dehydrated stream. Steam can be imported from outside the dehydration process such as from an oligomerization or dimerization reaction. Steam can be produced from the dehydrated stream.

  • Publication number: 20240109822
    Abstract: An integrated process for hydrogenating olefins wherein the hydrogen stream is generated from electrolysis of water is described. Water is derived from a first reaction step wherein a first feed stream comprising oxygenated hydrocarbons is reacted to produce a first reacted product stream comprising olefins and a second reacted product stream comprising water. The second reacted product stream is electrolyzed to produce an electrolyzer product stream comprising hydrogen. Hydrogen is used to hydrogenate olefins. A paraffin stream can be obtained from the hydrogenated effluent.

  • Publication number: 20240067586
    Abstract: A process for dimerizing and oligomerizing olefins to distillate fuels which utilizes a solid acid catalyst for ethylene oligomerization in a first stage and a metal catalyst for further oligomerization in a second stage. Distillate fuels can be produced from the process. Oligomerized olefins may be recycled to the first stage oligomerization reaction to ensure sufficient oligomerization of smaller olefins.

  • Publication number: 20240067584
    Abstract: A process for dehydration of ethanol to produce ethylene is provided. Ethanol is dehydrated to produce ethylene and the subsequent conversion of ethylene to longer chain olefins and then their hydrogenation to produce long chain paraffins. In some embodiments, a split feed is employed to improve efficiency and a caustic wash column is eliminated. The advantages of the process include a lower requirement for steam and a reduction in the combined reactor volume of 30-40% when two reactors are used as compared to a single reactor.

  • Patent number: 11888865
    Abstract: Systems and methods of the disclosure can implement intrusion radiation protection (IRP) to prevent malicious IP traffic in a secure network. The IRP system can receive an IP packet, determine that a protocol of the IP packet matches a predetermined policy of a plurality of predetermined policies, classify the IP packet based on the predetermined policy and a size of the IP packet, inspect a payload of the IP packet responsive to the classification to determine features of the IP packet, determine that one of the features of the IP packet is improper based on the classification, and flag the IP packet as suspect based on the determination. The IRP system can log and/or drop the flagged IP packet. The IRP system can additionally replace a payload of the IP packet with a second payload, and transmit the IP packet with the second payload to its destination.

  • Publication number: 20240025821
    Abstract: A process for dimerizing and oligomerizing olefins to distillate fuels which manages the dimerization exotherm by diluting it with paraffins which are inert in the dimerization. The olefin stream can also be split and fed to multiple dimerization reactors to further reduce the heat generated. The ethylene feed can also be cooled before entering the dimerization reactor. The paraffins can be obtained from saturating oligomerized effluent.

  • Publication number: 20230183585
    Abstract: A feed stream of cyclic paraffins may be separated to obtain an overhead of methylcyclopentane or cyclohexane and a bottoms stream cyclohexane or methylcyclohexane. The overhead stream may be subjected to separation of normal paraffins from non-normal paraffins with the former being isomerized or the entire overhead stream may be isomerized. In a further embodiment, the bottoms stream may be subjected to steam cracking. In an additional embodiment, the feed stream of cyclic paraffins may be formerly subjected to aromatic saturation.

  • Publication number: 20230139309
    Abstract: Methods for determining a volume of stored gas within a rock sample includes loading a rock sample into an overburden cell. A hydrocarbon gas at a gas pressure is applied to the rock sample and a confining fluid at a confining pressure is applied to the overburden cell. The confining pressure and the gas pressure are increased until a first pressure and temperature condition is met. With the rock sample maintained at the first temperature and pressure condition, a nuclear magnetic resonance spectrometer is used to scan the rock sample and measure a hydrocarbon gas volume within the rock sample. This measured hydrocarbon gas volume is then corrected using a Real Gas Index to determine the volume of stored gas within the rock sample.

  • Patent number: 11555154
    Abstract: The process removes hydrogen sulfide from hydrotreated gas by TSA. Hydrogen sulfide adsorbs on the adsorbent while allowing hydrogen in the hydrotreated gas to pass the adsorbent to provide a desulfided hydrogen gas stream and a sulfided adsorbent. A regenerant gas stream can be contacted with the sulfided adsorbent at a swing temperature to desorb hydrogen sulfide from the adsorbent into the regenerant gas stream. The regenerant gas stream can then be recycled to a hydrotreating reactor for processing biorenewable feed to provide hydrogen sulfide to the reactor. The desulfided gas stream can be purified to remove impurities such as carbon oxides and recycled to the hydrotreating reactor and/or used as the regenerant gas stream.

  • Publication number: 20220112430
    Abstract: The process produces a diesel stream from a biorenewable feedstock by hydrotreating to remove heteroatoms and saturate olefins. The recycle gas is recycled to the hydrotreating reactor without removing hydrogen sulfide, which is needed in the biorenewable feed to keep the hydrotreating catalyst active. A purification unit can be utilized on a purge gas stream to purify the gas and improve hydrogen concentration in the recycle gas when added to the recycle gas.
