1. A system for stimulating production of biomass comprising:
a loop reactor, the loop reactor including:
a fluid moving device having an inlet and an outlet, the inlet of the fluid moving device in fluid communication with an outlet of a substantially vertical downflow zone;
a loop section including an outlet and an inlet, the inlet of the loop section in fluid communication with the outlet of the fluid moving device;
a substantially vertical upflow zone including an outlet and an inlet, the inlet of the substantially vertical upflow zone in fluid communication with the outlet of the loop section; and
a gas/liquid separation vessel having a longitudinal axis and including:
an outlet and an inlet, the inlet of the gas/liquid separation vessel located in a lower portion of the gas/liquid separation vessel and in fluid communication with the outlet of the substantially vertical upflow zone, the outlet of the gas/liquid separation vessel in fluid communication with an inlet of the substantially vertical downflow zone;
an intermediate section between the outlet and the inlet of the gas/liquid separation vessel, the intermediate section having a constant diameter equal to D;
an outlet side section on one side of the intermediate section, the outlet side section including the outlet of the gas/liquid separation vessel; and
an inlet side section on a side of the intermediate section opposite the outlet side section, the inlet side section including the inlet of the gas/liquid separation vessel, a lowermost edge of each of the inlet, the outlet, the intermediate section, the outlet side section and the inlet side section of the gas/liquid separation vessel contact a common plane.
