It is possible to purify Shadow Lugia. You will need to create 9 perfect tempos in the purification chamber, place Lugia into the chamber, you will then be told something is happening to Lugia. Then you will see that Lugia heart gauge is flashing white.
It depends on the game. In the later, newer games you usually need a Mystery Event or Action Replay Code to see and get Lugia.

Lugia is in the Whirl Islands at level 70 in Pokemon HeartGold.
A person in Pewter City will give you the Silver Feather, then go to Whirl Islands. When you get to the end of the cave you will see Lugia.
It differs in each Generation. See Related link for each Generation. Note that Lugia didn't exist in Generation I
