Process brief
This process is an all-liquid air separation process integrating normal temperature molecular sieve adsorption purification, nitrogen cycle pressurization, high and low-temperature pressurized turbine expander, full distillation of packed fractionation tower to produce argon. And is one of the most advanced all-liquid air separation processes in the world.
Main feature :
1. The use of high and low-temperature expander refrigeration to obtain a larger unit enthalpy drop and improve the distillation conditions of the upper tower.
2. Use nitrogen recycling booster to pressurize and expand to reduce energy consumption.
