"Wait a minute does anyone knows what happens to the demon that got killed during the extermination."

The lore of the show states that the weapons carried by the Exterminators are the only things that can kill a demon permanently (Vaggie calls it being erased). Those Exterminator weapons left behind after the purges are collected and sold on Hell's black market.
