10 to 15 minutes by train. Take the 'brussels airport express' train in one of the three major railway stations (Nord, Central, Midi).
By car or taxi it depends of the traffic: when it's calm it's only 20 minutes, on a very busy day it may take an hour.
Take the train direct from the airport. You may have to change at Bruxelles Nord or Centrale!!
