  • APPARATUS AND PROCESS FOR HYDROGEN RECYCLING TO AVOID LIQUEFIER SHUTDOWN DUE TO INSUFFICIENT FEED OF HYDROGEN
    Publication number: 20260049761
    Abstract: An apparatus and process for recycling hydrogen can be provided so that hydrogen is recycled during hydrogen liquefaction processing to account for an unexpected loss of feed of hydrogen so the recycled hydrogen can be provided to avoid liquefier operations having to be shut down. Embodiments can utilize a parahydrogen to ortho-hydrogen conversion unit to facilitate such recycling of hydrogen to avoid liquefaction processing problems in liquefaction of the recycled hydrogen included into the feed to account for the loss of fee hydrogen.

  • Removal of dissolved gases for boiler feed water preparation
    Patent number: 8876955
    Abstract: Method for removing dissolved gases from water to produce boiler feed water in a catalytic steam reforming process where boiler feed water is heated by indirect heat transfer with a reformate stream and/or a combustion product gas stream and the boiler feed water subsequently flash vaporized to form steam and residual liquid water, where the steam formed by flash vaporization strips the dissolved gases from the water.
