一、Core characteristics of 316 metal Intalox saddle ring packing

Material advantages

Corrosion resistance: Adding 2-3% molybdenum (Mo) to 316 stainless steel significantly improves its resistance to pitting corrosion and marine/industrial atmospheric corrosion, making it suitable for ethane dry environments containing acidic gases such as CO ₂ and H ₂ S.

High temperature strength: It can work stably at high temperatures of 1200-1300 °C and withstand possible high temperature conditions during the drying process of ethane.

Mechanical properties: After cold rolling, the surface glossiness is high, the work hardening is strong, the solid solution state is non-magnetic, and it is suitable for long-term pressure operation.

Structural advantages

Channel design: Combining circular and saddle shaped structures, with a specific surface area of up to 90.1 m ²/m ³ (DN50 specification) and a porosity of 97%, significantly reducing gas resistance and improving flux.

Mass transfer efficiency: The unique arc-shaped liquid channel promotes uniform distribution of gas-liquid, reduces radial diffusion, and improves drying efficiency.

Anti clogging: High porosity and regular structure reduce solid particle deposition, lower clogging risk, and facilitate cleaning and maintenance.

二、Applicability of 316 metal Intalox saddle ring packing in ethane drying

Corrosion resistance matching

316 material can resist the corrosion of trace acidic gases in ethane, avoid damage to the packing layer, and reduce the frequency of replacement.

Efficient Mass Transfer and Energy Conservation

High specific surface area promotes gas-liquid contact, shortens drying time, and reduces tower height requirements.

Low pressure drop design reduces compression energy consumption and meets the energy efficiency requirements for ethane drying.

Operation stability

High temperature resistance prevents deformation of the filler under high temperature conditions, ensuring long-term stable operation.

The regular structure reduces uneven liquid distribution and prevents local overheating or coking.

Anti clogging and easy maintenance

High porosity reduces particle deposition, lowers the risk of blockage, and prolongs the operating cycle.

The design of loose packing material facilitates disassembly and cleaning, reducing maintenance costs.
