  • Apparatus and method for increasing the concentration of recycled hydrogen in a high pressure hydrogenation reactor
    Patent number: 7785547
    Abstract: An apparatus and a method that increase the concentration of recycled hydrogen in the hydrogenation unit are disclosed having a hydration separation unit included between the high-pressure separator and hydrocracking reactor. A part of the recycled hydrogen contacts with the water-in-oil microemulsion to form hydrates from which the light hydrocarbon components are removed. The gas flow entering into the hydration separation unit is present in amount of 20%˜100% of the total gas flow coming from the high-pressure separator; the water-in-oil microemulsion, in which the volume ratio of oil and water is 1:1 to 5:1 may increase hydrogen partial pressure in the reactor and thus upgrade the performance of hydrogenation.

  • Combined process for recovering hydrogen, ethylene, ethane or separating ethylene cracked gas from dry gas of refinery plants
    Publication number: 20050277801
    Abstract: This application provides processes for recovering hydrogen, ethylene and ethane from dry gas or separating ethylene cracked gas from dry gas of refinery plants, wherein a hydrating separation may be combined with for example a freezing or absorbing separation so as to separate a multiple gas mixture.
