Claim 1:
2. The system of claim 1, further comprising:
a stripping gas control valve on the stripping gas feed line;
a stripping gas flow indicator on the stripping gas feed line configured to measure a flow of a stripping gas which has passed through the stripping gas control valve;
a first condensate input line flow indicator on the first condensate input line, wherein the first condensate input line flow indicator is configured to measure a first condensate flow through the first condensate input line;
a second condensate input line flow indicator on the second condensate input line, wherein the second condensate input line flow indicator is configured to measure a second condensate flow through the second condensate input line;
a reboiler thermocouple connected to the reboiler return line of the stripping column;
an overhead thermocouple connected to the overhead gas product line; and
a ratio controller, wherein the ratio controller is configured to receive a first signal from the first condensate input line flow indicator, a second signal from the second condensate input line flow indicator, a third signal from the stripping gas flow indicator, a fourth signal from the reboiler thermocouple, and a fifth signal from the overhead thermocouple.
