The invention relates to a method for providing high-pressure oxygen using low-pressure oxygen containing water, in which method the low-pressure oxygen is subjected to a drying process and subsequently to a pressure increase, the drying process comprising an adsorption step. In the adsorption step, a regeneration gas is used which is provided using oxygen that is provided using the pressure increase and using at least part of the low-pressure oxygen. The pressure increase is performed above 0° C. and using a plurality of compressors or compressor stages which have an intercooler between two compressors and/or compressor stages. At least part of the oxygen which is used to form the regeneration gas is removed from the pressure increase between two of the compressors or compressor stages upstream of the intercooler. Alternatively, the pressure increase is carried out by means of internal compression.
A method for providing high-pressure oxygen (H) using low-pressure oxygen (L) containing water, in which the low-pressure oxygen (L) is subjected to a drying process and then to a pressure increase, wherein the drying process comprises an adsorption step, wherein, in the adsorption step a regeneration gas (R) is used which is provided using oxygen which is provided using the pressure increase and using at least a part of the low-pressure oxygen (L), wherein the pressure increase is performed above 0° C. and using a plurality of compressors or compressor stages which have an intercooler between two compressors and/or compressor stages, and in which at least a part of the oxygen used to form the regeneration gas (R) is removed from the pressure increase between two of the compressors or compressor stages upstream of the intercooler.
A method for providing high-pressure oxygen (H) using low-pressure oxygen (L) containing water, in which the low-pressure oxygen (L) is subjected to a drying process and then to a pressure increase, wherein the drying process comprises an adsorption step, wherein, in the adsorption step, a regeneration gas (R) is used which is provided using oxygen which is provided using the pressure increase and using at least a part of the low-pressure oxygen (L), wherein the pressure increase comprises cryogenically liquefying at least a part of the low-pressure oxygen (L) subjected to the drying process and then the pressure increase to obtain a cryogenic liquid, pressurizing at least a part of the cryogenic liquid in the liquid state to obtain a pressurized, cryogenic liquid, and converting at least a part of the cryogenic and pressurized cryogenic liquid into the gaseous or supercritical state.
A system for providing high-pressure oxygen (H) using low-pressure oxygen (L) containing water, which is designed to subject the low-pressure oxygen (L) to a drying process and then to a pressure increase, and to carry out the drying process using a temperature swing adsorption, wherein, the system is designed to use a regeneration gas (R) in the temperature swing adsorption, to form the regeneration gas (R) using oxygen, and to provide the oxygen used to form the regeneration gas (R) using the pressure increase and using at least a part of the low-pressure oxygen (L), wherein a device is used for the pressure increase, the device having
