The leader of pressure swing adsorption technology

Separation of CO by pressure swing adsorption

Carbon monoxide is an important basic chemical raw material for the production of acetic acid, acetic anhydride, oxalate, ethylene glycol, oxalic acid, dimethylformamide, dimethyl carbonate, formic acid, etc., and phosgene synthesis to further generate TDI, MDI, etc. . The pure carbon monoxide required for chemical synthesis can be separated and extracted from various carbon monoxide-containing gas mixtures. The raw material gases that can be used to separate carbon monoxide in the industry include: synthetic gas converted from natural gas and petroleum, water gas, semi-water gas, and steel plants, calcium carbide plants and Exhaust from yellow phosphorus plant. The use of pressure swing adsorption technology to separate carbon monoxide is an emerging international technology in recent years. The highly efficient adsorbent PU-1 developed by Peking University has extremely high adsorption capacity and selectivity for carbon monoxide, and has won patents from China, the United States and Canada. Based on the characteristics of this adsorbent, Peking Pioneer has successfully developed a new internationally advanced, high-efficiency and low-consumption PSA separation technology to solve the problem of separating high-purity carbon monoxide from raw gas with high nitrogen or methane content.

Technical introduction
Beida Pioneer has designed and built a number of large-scale carbon monoxide separation devices, which has brought huge economic benefits to users and has been highly evaluated. This technology was rated as "Top Ten Scientific and Technological Progress in Chinese Universities" in 2005 and won the second prize of National Technology Invention Award in 2006.
  • Performance

    Oxygen production scale:
    100 ~ 40000Nm³ / h

    Product purity:
    Normal design value ≥98.5%, purity can be adjusted flexibly, up to 99.99%

    Carbon monoxide yield:
    When the purity is 98.5%, the yield is 75 ~ 95%

    Device consumption:
    When the product yield and purity are the same, the energy consumption is more than 30% lower than other domestic PSA processes, and the amount of raw material gas is saved by more than 50%

  • Technical characteristics and advantages

    The feed gas has good adaptability. <br /> High efficiency carbon monoxide adsorbent PU-1 can be used to separate high-purity carbon monoxide from feed gas with high nitrogen or methane content.

    Low product carbon monoxide cost <br /> Advanced device technology, high product yield, low raw material consumption, small supporting equipment load, and low production cost.

    High carbon monoxide quality <br /> The product has high carbon monoxide purity (up to 99.99%) and small impurity content, which is very beneficial to downstream production and can bring significant economic benefits.

    The existing device of the user can be modified. <br /> Without increasing the operating cost, the production and quality of carbon monoxide in the domestic PSA device can be greatly improved.
