You need a hot-air station with serious output for those kinds of components. The problem is heat dissipation, but if you heat up the surroundings the dissipation gets much lower and youl'l be able to remove the chip. Alternative is using a preheater to get the whole board at (say) 100°C. But still, it requires a lot of heat to remove any kind of BGA style package.
