    Abstract: The invention relates to a method of enriching a pressurised gas stream (1) with one of the components (A) thereof. The inventive method comprises the following steps: the stream is separated into at least first and second fractions (2, 3); at least one part of the first fraction (2) is sent to a separation unit (ASU); the separation unit supplies at least two discharges, including a first discharge (10) having a greater A content than that of the fraction (2) supplied to the separation unit; at least one part of the first discharge (10) is mixed with at least one part of the second fraction (3) such as to form a pressurised gas mixture (15); the second fraction (3) is expanded and, subsequently, at least one part of the first discharge (10) is mixed therein.

    Abstract: The invention relates to a process for producing oxygen or air enriched with oxygen, in which process: The air entering the process is cooled in a heat exchanger (14) to near to the condensation point of air and the air is led to a separation unit (10) formed of two or more chambers connected thermally to each other and comprising A and B halves (11, 12), in which it is divided, using liquidization and evaporation processes, into two or more gaseous fractions. The process air is maintained at normal temperature, except for small pressure differences to maintain the flow of the air and to optimize the process. When the process air flows through the A half of the separation unit, the liquid oxygen concentrate separated from it is evaporated in the B half (12) of the separation unit at such a pressure, lower than normal pressure, that the desired composition is obtained for the oxygen concentrate and the heat of liquidization released in the A half (11) of the unit is transferred to the B half (12) of the unit and is bound in it to the evaporation of the oxygen concentrate. The low-oxygen-content process air leaving the A half (11) of the separation unit is led out of the process through the heat exchanger (14). The oxygen concentrate evaporated in the B half (12) of the separation unit exits at the lower than normal pressure prevailing in the half in question, either as such, or through a boosting and cooling process to the heat exchanger (14), and from there out of the process. The liquidization and evaporation processes are carried out in the said separation unit (10) in nearly reversible conditions, in such a way that the gas phase in each process and in each part of the separation unit is nearly in equilibrium with the liquid phase in the same part.

    Abstract: The invention relates to a method and a device for evaporating liquid oxygen. During normal operation, liquid oxygen is introduced into a main evaporator (3) where it is partially evaporated, a first rinsing stream (5) is removed from the main evaporator (3) as a liquid, the first rinsing stream (5) is partially evaporated in a supplementary evaporator (6) and a second rinsing stream (7) is removed from the supplementary evaporator (6) as a liquid. Normal operation is then interrupted by a heating up mode in which no liquid (5) is guided out of the main evaporator (3) into the supplementary evaporator (6) and the supplementary evaporator (6) is heated up to a significantly higher temperature than its temperature during normal operation.
