Adopting double expander process to save power consumption which comparison with common single expander process

This Liquid Oxygen Plant adopts the process of air purified by molecular sieve, with booster of turbo expander.

The guaranteed performances of the plant refer to the performances reachable during normal running under designed basic conditions and also the predicted performances under limit conditions

Products specifications at outlets of cold box (Output & purity):

Case I (Design Case)

Product	Output		Purity	Pressure outlet of cold-box / temperature
LOX (Liquid oxygen)	(Kg/h)	(Nm3/h)	99.6%O2	~0.16 MPa(G)/-177 °C
	1000	700

Case II

Product	Output		Purity	Pressure outlet of cold-box / temperature
LOX (Liquid oxygen)	(Kg/h)	(Nm3/h)	99.6%O2	~0.16 MPa(G)/-177 °C
