Method for cryogenic separation of air in distillation column-system for nitrogen-oxygen separation, involves withdrawing liquid from high-pressure column in flowing manner and discharging liquid into low-pressure column
摘要
<p>The method involves withdrawing a liquid from a high-pressure column (2) in a flowing manner and discharging the liquid into a low-pressure column (3). A liquid jet pump is used for transfer of the liquid from the high pressure column into the low pressure column. Another liquid is withdrawn from the high-pressure column in a flowing manner. An independent claim is also included for a device for cryogenic separation of air in a distillation column-system for nitrogen-oxygen separation.</p>
