β¦ Synopsis
The plants have been considered which are meant for simultaneous production ofgaseous and liquid oxygen, nitrogen and argon, and which are designed according to the schematic diagrams of low pressure, medium pressure and two pressures with a nitrogen cycle. On the basis of the procedure developed for technical and economical optimization, the optimum values of oxygen and argom recovery from air have been defined; the relationships between power consumption and reduced costs as well as between other parameters and the fraction of the products in a liquid state have been described. Presented are the ranges of the liquid product fraction variations for which the use of a particular schematic diagram of the plant is essential.
