Cryogenic rectification system for lower pressure operation. |
摘要 |
<p>A double column cryogenic rectification system wherein lower pressure column (42) bottoms undergo additional rectification within a once-through downflow reflux condenser (41) by countercurrent direct contact flow with vapor generated by condensing higher pressure column shelf vapor (70) enabling the higher pressure column (40) to operate at a reduced pressure thus reducing feed compression power requirements. <IMAGE></p> |
