VAPORIZATION OF LIQUID OXYGEN FOR INCREASED ARGON RECOVERY |
摘要 |
The present invention relates to an improvement for the production of argon from cryogenic air separation processes. In particular, the improvement comprises satisfying a portion of the the crude argon column condensing duty with refrigeration (128) provided from the vaporization of a portion (159) of the liquid oxygen from the bottom of the low pressure column (119). <IMAGE> |
