SUTONG structured packings are characterized by the Patent of ZWF Technology.ZWF means "Zero Wall Flow".Wall flow of the normal structured packing is above 30% at least, and mostly above 40%. The loss ratio of the packing separation efficiency is 15%-24%. ZWF structured packing can overcome the loss of the separation efficiency caused by wall flow. It can keep the wall flow below 2%.

  • Carbon Capture Utilization and Storage
    Carbon Capture Utilization and Storage

    Carbon Capture, utilization and Storage is one of the key technologies to cope with global climate change. This technology is a new development trend of CCS (Carbon Capture and Storage) technology, that is, the carbon dioxide emitted in the production process is purified and then put into the new production process, which can be recycled,rather than simply storage. Compared with CCS, carbon dioxide can be recycled, which can produce economic benefits and is more practical.
