Xenon is produced commercially in an air separation plant.
The air is liquified and distilled. The crude xenon and krypton, which means it is not in the final state, are then further purified by distillation and selective abosrbation. The controlled low tembetures, are on activited carbon. The remaining impurities are removed by passing the xenon over hot titanium, which reacts wiht all but the inert gases. It is used in high speed photography for flashlamps.
