1. A method for maintaining solvent quality in a gas treating system, the method comprising:
calculating, by an advisory system for continuous monitoring of the gas treating system, a water content deficit in a solvent of the gas treating system;
calculating, by the advisory system, a water makeup rate compensating for the water content deficit;
displaying, in an interactive user interface of the advisory system, the water makeup rate;
adjusting the water makeup rate based on the calculated water makeup rate;
determining a health of at least one level transmitter of the gas treating system,
wherein the at least one level transmitter is configured to measure a current total volume of solvent in the gas treating system;
wherein determining the health of the at least one level transmitter comprises comparing a plurality of independent measurements performed by different sensors of the at least one level transmitter, and
wherein a discrepancy of the independent measurements larger than 10% is indicative of a malfunction;
displaying, in an interactive user interface of the advisory system, the health of the at least one level transmitter; and
calculating, by the advisory system, a water loss rate based on a water content of outlet gas streams of the gas treating system,
wherein calculating the water content deficit comprises:
predicting an estimated amount of water in the gas treating system over time; and
determining a difference between a desired amount of water and the estimated amount of water in the gas treating system.
