PROCESS BRIEF

This ASU design is based on the principle of long-term steady operation, low energy consumption, easy management & maintenance and should be of the international advanced technology. It is of an internal compression process of oxygen, with molecular sieve purification system, turbo-expander with booster and upper packing column, using the technology of expanded air entering upper column. The output oxygen and nitrogen pressure can reach as high as 8.5MPa, which meets the diversified requirements of oxygen and nitrogen pressure in the chemical industry. The yield pressure is adjustable up to 8.5 MPa, which satisfies the diversified requirements of industrial gas pressure in the chemical industry.

    Advantages

    1. Adopt the internal compression process and MS adsorbers system, Oxygen and Nitrogen is pumped into high pressure inside cold box and product compressor is not necessary.
    2. Adopt the water cooling tower to recover the cold resource from waster nitrogen gas, to make full use of moisture adsorption character of dry nitrogen gas.
    3. All rectifying columns adopt structural packing type, which reduces the operation pressure and saves electricity consumption of MAC.
    4. The range of load adjust will be in scope of 80-110%, which is flexible for the client use.
