For serious reflow work, you can use a hot-air pencil. For hand re-work of SMD stuff, solder paste and an application needle are pretty much required.
With a hot air pencil, you cover the surrounding components, and gently heat the PCB and chip, a pair of tweezers lifts it off once its flowed.
In a few desperate (and dirt poor) situations, I have reflowed otherwise junk boards in an oven. A digital thermometer and extreme care are needed, as even a slight bump will send components flying...
