To calculate kg/hr moisture removal
kg/hr = vol x delta kg/kg x 3600 / specific volume
You need to use a Psychrometric Chart
from your figures - 35C @ 80% and 10C @ 50% the results are
Vol = 0.416m3/s
Delta kg/kg = 0.0256
Sp Vol = (0.806 + 0.914/2) = 0.86
so
kg/hr = 0.416 x 0.0256 x 3600 / 0.86 = 44.57
Looking at the spec sheet for the FXFQ80P9 it will not handle the volume or the humidity
The maximum volume on high speed is 1410m3/hr but more importantly, it is only rated at 9.9kW cooling duty and you need 15kW

What you asking is this:

That is if you have dehumidifier which will dehumidify all new air in one pasage. But, that is not your case.
You have air-conditioner which will cool same air and dehumidify it in multiple pases through it.
This is from tehnical data:
