Stainless Steel Random Packing: Effective Solutions for Distillation and Absorption Processes

Introduction

Stainless steel random packing is widely used in industrial separation processes for distillation, absorption, and stripping columns. Wangdu (Hebei) Chemical Engineering Co., LTD manufactures various types of stainless steel random packing that provide reliable performance in chemical processing applications.

Types and Designs

Common stainless steel random packing types include:

1. Pall Rings

• Cylindrical shape with internal struts

• Available in multiple sizes (15mm to 100mm)

• Improved liquid distribution compared to basic rings

2. Raschig Rings

• Simple cylindrical design

• Basic but effective geometry

• Suitable for many standard applications

3. Intalox Saddles

• Saddle-shaped design

• Enhanced surface contact

• Good hydraulic performance
