Abstract
An arrangement for generating oxygen in a facility is described, which arrangement has at least one unit for generating medical air (V, R), a vacuum system (VS), and a PSA unit (A), which serves to generate an oxygen product stream. According to the invention, the PSA unit (A) and the vacuum system (VS) are interconnected in such a way that the adsorber or adsorbers of the PSA unit (A) can be regenerated by means of the vacuum system (VS), and/or the unit for generating medical air (V, R) is connected to the PSA unit (A) in such a way that at least a subsidiary stream (2) of the generated medical air is delivered as feed gas to the PSA unit (A).
Claims23
A system comprising comprising:
- at least one unit for generating medical air (V, R), a PSA unit (A) which serves to generate an oxygen product stream, and a facility comprising a line network for medical air, an oxygen line network, and a vacuum system (VS),
- wherein said at least one unit for generating medical air (V, R) is connected to the line network for medical air in such a way that a first subsidiary stream generated medical air is delivered from said at least one unit for generating medical air (V, R) to said line network for medical air,
- said at least one unit for generating medical air (V, R) is connected to said PSA unit (A) in such a way that at least a second subsidiary stream (2) of generated medical air is delivered as feed gas to said PSA unit (A), and
- said PSA unit (A) and said vacuum system (VS) are interconnected in such a way that the adsorber or adsorbers of said PSA unit (A) can be regenerated by means of said vacuum system (VS).
