It depends how precise and accurate a result you need. First of all realise that what will vaporize will not be the same as the liquid. At 90 deg C what will come off will be about 3% MEA, so what will be vaporizing is water. Thus to a first approximation, the enthalpy of vaporization is that of water.
This is a well-known system, so you can easily find papers on its vapor-liquid equilibrium.
