1. A device for directing a liquid to a reactor, the device comprising:
an inner tube positioned concentrically within an outer tube, creating a first annular space between an outer wall of the inner tube and an inner wall of the outer tube; and
a first intermediate tube positioned concentrically around the outer tube, creating a second annular space, wherein:
the first intermediate tube has a proximal end and a distal end,
the inner tube has a proximal end and a distal end,
the outer tube has a proximal end and a distal end,
the proximal end of the inner tube is configured to receive the liquid,
a portion of the first annular space in a proximity near the proximal end of the inner tube and the proximal end of the outer tube is configured to receive a first gas,
the distal end of the inner tube contains an outlet configured to release the liquid,
the distal end of the inner tube and the distal end of the outer tube are substantially aligned and form a gap between the outer wall of the inner tube and the inner wall of the outer tube,
the gap is configured to direct the first gas to the liquid exiting the second end of the inner tube, and
the second end of the outer tube terminates with a tip configured to mix the liquid with the first gas and to direct the liquid and the first gas into the reactor.
