With rich experience in the field of new energy and excellent technical solutions, thoughtful pre-sale, in sale and after-sale service concepts, DEAR air separation stands out among many bidding companies and successfully signs the gas supply contract of KDON-6000 / 3200 air separation plant. Yongxu Company plans to invest 1300 million yuan to build a "comprehensive utilization project of 600000 tons of waste battery resources annually" in Qinbei Park, Qinyang industrial cluster, which is currently under construction.
The unit adopts molecular sieve purification, booster turbine expander to supply the cooling capacity of the unit. The oxygen concentration is low (90% O2), the air compressor discharge pressure is very low 0.42MPa(G), and the energy consumption of the whole equipment is low.
1.Good safety: The oxygen evaporator is set to reduce the liquid oxygen concentration ofthe main cooling. At the same time, a large amount of liquid oxygen is discharged from the main cooling to reduce the risk of hydrocarbon accumulation in the main cooling.
2.Increase benefit: Liquid oxygen products for temporary use of backup system
3.Reasonable utilization: adopt air-cooled and cold water pre-cooling mode, make full use of waste nitrogengasto achieve the purpose of energy saving.
4.Advanced control: DCS control, high degree of automation, convenient operation.
5.Energy saving and consumption reduction: new molecular sieve is adopted to reduce air flow resistance, reduce air compressor discharge pressure and save energy. Reduce the heating time of molecular sieve regeneration and save the energy consumption.
