Abstract:This paper introduces the characteristics of air separation equipment energy consumption, and analyzes the influence of air separation condition conversion on the unit energy consumption, and introduces the main operation modes of air separation conversion conditions and the energy consumption change in each process link during the condition adjustment. Combined with the actual benefit data, the comprehensive benefit changes of the main liquid oxygen condition and the main liquid nitrogen condition are compared and analyzed, the idea of technical transformation of the air separation automatic variable load is put forward.
