Abstract

THE PRESENT INVENTION IS DIRECTED TO TWO EMBODIMENTS OF A PROCESS FOR RECYCLING AN IMPURE ARGON EFFLUENT FROM A SILICON CRYSTAL GROWING FURNACE(18) USING CRYOGENICS. THE FIRST EMBODIMENT USES CRYOGENIC DISTILLATION TECHNIQUES, AND THE SECOND EMBODIMENT USES CRYOGENIC ADSORPTION, BOTH OF WHICH USE CATALYTIC TREATMENTS AND ADSORPTION IN CONJUNCTION WITH THEIR CRYOGENIC PROCESS STEPS TO PROVIDE A PURE ARGON RECYCLE STREAM FOR A SILICON CRYSTAL GROWTH FURNACE(18).
