  • Apparatus, process and system for delivering fluid to a distillation column or reactor
    Patent number: 8486233
    Abstract: A fluid delivery apparatus is provided for supplying a fluid mixture to a distillation column or reactor. The apparatus can be used to enhance the heat duty, the flow and/or the flow stability of an existing thermosiphon reboiler which supplies a heated fluid to the column or reactor. The apparatus includes an integrated eductor which receives and increases the fluid velocity of a supplemental fluid into which the heated fluid is aspirated to form a fluid mixture then delivered to the column or reactor. A process and a system utilizing the apparatus are also disclosed, as well as a method of retrofitting an existing system with the apparatus.
