Frequently Asked Questions

Your Guide to Structured Packing Solutions

Discover how Sutong’s structured packing optimizes efficiency, durability, and performance across industrial applications.


How do Sutong's structured packings achieve lower pressure drop (ΔP) and higher capacity (CF) compared to international competitors?

A:

Data Highlights:

  • Pressure Drop Reduction: Down by 65%
  • Capacity Factor (CF): Greater than 2.5
  • Open Area: Greater than 40%


For comparison, Sulzer Mellapak™ typically has a pressure drop reduction of 40%, a capacity factor between 1.8 and 2.0, and an open area of 25-30%. Koch-Glitsch generally shows a pressure drop reduction of 35%, a capacity factor between 1.7 and 1.9, and an open area of 20-25%.

Principle: Our honeycomb channel design, combined with a 30° inclined corrugated structure, optimizes the airflow path. In a real application at Zhejiang Petrochemical's FCC unit, our packing achieved a pressure drop of only 112 Pa/m, compared to the 320 Pa/m experienced with traditional packings.

What’s the service life in corrosive environments (e.g., HF acid, amine solutions)?

Our Four-Dimensional Material Solution:

  • Ceramic Grids: Resistant to 10% HF acid corrosion with a lifespan of over 18 months, significantly longer than the under 6 months of traditional 316L packing.
  • PTFE Modified Plastics: Suitable for -196℃ liquid oxygen air separation towers, with a resistance to cracking from freezing greater than 15kJ/m².
  • Certifications: We hold ISO 14001 environmental management system certification and the Samsung 9000 AA-level corrosion resistance certification.

Does the swaying of a ship's desulfurization tower affect separation efficiency?

Our Disturbance-Resistant Design:

  • The honeycomb structure effectively distributes liquid flow, preventing uneven distribution. The 30° inclined corrugated structure can withstand tilt amplitudes of over 5°.
  • Real-world testing in an IMO 2020 project showed that sulfur capture rate fluctuations were less than 1%, easily meeting the mandatory standard of 99.5%.

Can Sutong's structured packing meet the ppm-level separation requirements for electronic-grade chemicals?

TPrecision Manufacturing Capabilities:

  • Our BX wire mesh has a tolerance of ±0.005mm, significantly tighter than the industry standard of ±0.02mm. This results in metal ion leaching of less than 0.1ppb.
  • Our packing can operate under a vacuum down to less than 10Pa and achieve over 28 theoretical stages, enabling a purity of 99.99% for pharmaceutical intermediates.
