Beschreibung
Zusammenfassung:	The invention provides an energy recovery optimization method for a large air separation steam-electricity double-drive coaxial unit. The method comprises the following steps that firstly, the large air separation steam-electricity double-drive coaxial unit with an independent lubricating oil and adjusting oil system is adopted; 2, automatic starting control of an oil pump is adjusted; step 3, controlling the operation of the large air separation steam-electric double-drive unit; fourthly, automatic stop control over the oil pump is adjusted; and 5, adjusting interlocking control of the oil pump. Aiming at industries such as nonferrous metallurgy, the steam turbine is adopted as a waste heat recovery system and drives the air compressor to operate together with the motor, waste heat energy is directly converted into mechanical energy from heat energy, the recovery efficiency is high, normal operation of a main process is not affected, meanwhile, the unit further has a power generation function and can replace
