  • Abstract(Eng)
  • In this work, a study for the reduction of the electric power consumption has been estimated in main air compressors in the air separation unit through cryogenic distillation columns with PRO/II with PROVISION V10.2 at AVEVA company. Both required LNG mass flow rate and cold heat contained in 1 ton of LNG were also predicted using Peng-Robinson equation of state with Twu’s new alpha function. Through this work, we concluded that 32.33―48.69% of electric power could be saved by using LNG cold heat.
