Coal based power plant of 210MW generation capacity emits flue gas at a rate of 900tonnes per hour. If CO2 is captured from this capacity of gas, based on amine absorption technology, the reboiler of the amine regeneration column requires heat supply at 190MJ/second as per the simulation results.Considering this as the additional total energy requirement for the CO2 capture process, how much power can be actually generated?

Based upon the scenario you have provided you can generate 210 MW of power. But you have to spend 190MW to capture the CO2. The net power is 20 MW. 90% of the power generated goes to abating CO2. Ya gotta love Al Gore.

If your numbers are correct, somewhere around 20 MW. But doesn't a lot of the thermal energy for the reboiler come from the flue gas itself?

We have the conversion factor
1MJ=.2777 KWh=.2777*3600 KWsec
1MJ/sec=.2777*3600KW
190MJ/sec=.2777*3600*190 KW
=279921.6 KW
=279.9216 MW

1 watt = 1 J / sec
190 MJ /sec = 190 MW
(I think something is wrong with your question)
