🐛 Dehydration Glycol Column Test and Bug Fixes

[Sviatose]

Dehydration Glycol Column Test:
I've created a new test for the dehydration glycol column. I encountered convergence issues at 85 degrees C temperature of the condenser. Increasing the number of trays to 2 improves the convergence, however, this led to insufficient water content in the gas outlet streams, resulting in a water mass balance issue. Increasing temperature to 95C solves the water imbalance.

Incorrect Flow Rate Calculation:
When using the getFluid().getComponent("water").getFlowRate("kg/hr") method to obtain the flow rate of a particular component got a strange result.

first assert is ok if summing water in both gas and liquid feed
double waterFlowRateInColumn =
richTEGStream.getFluid().getPhase(0).getComponent("water").getFlowRate("kg/hr")
+ richTEGStream.getFluid().getPhase(1).getComponent("water").getFlowRate("kg/hr");

I see. But I guess it should return also correct value if richTEGStream.getFluid().getComponent("water").getFlowRate("kg/hr") ?

Seems to be an error that the liquid from top stage, is not introduved in the lower stage (2nd stage):
