Low operation pressure air separation plant
Liquid oxygen plant

We can design, manufacture and complete air separation plant according to end users' climatic, geologic and water quality conditions, as well as their different purity and quantity requirements for oxygen, nitrogen and argon.

We have capability to design and fabricate gaseous air separation plant with capacity from 1,000Nm3/h to 6500Nm3/h as well as liquid air separation plant with capacity from 720Nm3/h to 3,000Nm3/h to satisfy different requirements from customer.

Features of our plant:
1) The process is a sort of wholly low-pressure refrigeration recycles; high efficiency
turbo expander is adopted to refrigerate and adjustable nozzle is used to adjust
refrigeration amount
2) High efficiency isothermal turbo air compressor, gas cooler and water separator
are adopted; the whole unit is with high isothermal efficiency, less energy
consumption and reliable running
3) Aluminum plate fin heat exchanger is adopted, which is with compact structure,
low flow resistance and high heat transfer efficiency
4) Adopts molecular sieve purification system, and the production ratio between
O2and N2 is 1:2.5, with simplified process, less matching equipment, and
easier erection and operation
5) The DCS system can be adopted according to end users' requirements to realize
automatic control and reduce power consumption.
