Abstract
Air is distilled in a single column (8) installed on a boat, and from here an oxygen-enriched liquid flow is drawn-off. This flow is pressurized by a pump (9) and vaporized by heat exchange with air or nitrogen. The oxygen (105) is used for the partial oxidation of a flow (101) containing hydrocarbons, for example natural gas.
Claims7
In a process for separating air by cryogenic distillation in a single column having a boiler at the bottom of said column, which comprises:
- sending air to be distilled into a single column, where the air is separated into a nitrogen-enriched vapor and an oxygen-enriched liquid;
- heating the base of the column with the boiler;
- withdrawing from the column at least some of the oxygen-enriched liquid;
- and
- pressurizing and vaporizing withdrawn oxygen-enriched liquid by heat exchange with a pressurized flow;
- the improvement which comprises heating the boiler with an air flow.
