Abstract

At the enterprises where in processes of electrolysis productions the hydrogen, is a necessity for use also oxygen. This difficultly to make if oxygen leaves from electrolyser at the pressure near atmospheric. Usually for this purpose establish the separate oxygen compressor. When at the enterprise are engaged in gasification of liquid oxygen, it is possible for compression of electrolysers oxygen of low pressure to use the gas-jet ejector. The energy of expansion of oxygen of a high pressure in ejector is spent for compression of oxygen of low pressure from 0,1 up to 0,3 МPа. For an estimation of efficiency of ejector characteristics of compound «compressor-expander» (with which help also is possible to solve the specified problem) are analysed. Comparison has shown that the received efficiency of ejector 0,5 meets to efficiency compound, when efficiency expanders is 0,8 and efficiency of the compressor is 0,65. It specifies on expediency of application of ejector for compression of oxygen of low pressure with the help of some quantity of oxygen of a high pressure.
