  • Olefin production utilizing condensate feedstock
    Publication number: 20070208207
    Abstract: A method for utilizing natural gas condensate as a feedstock for an olefin production plant wherein the feedstock is subjected to vaporization and separation conditions that remove light hydrocarbons from the condensate for thermal cracking in the plant, and leave liquid distillate for separate recovery.
    Type: Application

    Applicant: EQUISTAR CHEMICALS, LP
    Inventor: Donald Powers
  • Olefin production utilizing whole crude oil feedstock
    Publication number: 20070055087
    Abstract: A method for utilizing whole crude oil as a feedstock for the pyrolysis furnace of an olefin production plant wherein the feedstock is subjected to vaporization conditions until substantially vaporized with minimal mild cracking but leaving some remaining liquid from the feedstock, the vapors thus formed being subjected to severe cracking in the radiant section of the furnace, and the remaining liquid from the feedstock being mixed with at least one quenching oil.

  • Containment, shielding, information display, distribution and administration of radioactive pharmaceuticals
    Publication number: 20050107698
    Abstract: A shielded radioactive medical apparatus has a tubular housing with a quick release cap configured for closing an open end of the tubular housing. A quick release mechanism holds the quick release cap on an open end of the tubular housing. A data display module on the housing communicates with an outside computer for receiving and transmitting information. The data display model also calculates and displays the radioactivity of a dose within the housing.

  • Propylene production
    Publication number: 20050043574
    Abstract: A method for making propylene from alpha olefins, internal linear olefins and isoolefins wherein the alpha olefins are subjected to a combination of hydrogenation and double bond isomerization to form additional internal linear olefins, the internal linear olefins are disproportionated with ethylene to form a propylene product, while the isoolefins are subjected to skeletal isomerization to form yet additional internal linear olefins to be converted into yet additional propylene.

  • Olefin production utilizing whole crude oil and mild controlled cavitation assisted cracking
    Publication number: 20050010075
    Abstract: A method for utilizing whole crude oil as a feedstock for the pyrolysis furnace of an olefin production plant wherein the feedstock after preheating is subjected to mild thermal cracking assisted with controlled cavitation conditions until substantially vaporized, the vapors being subjected to severe cracking in the radiant section of the furnace.
