Stripper Column

Shreewire Stripping Columns are engineered systems designed for the efficient removal of volatile organic compounds (VOCs), such as benzene, toluene, xylene, and low-boiling solvents like methanol and ethanol from water streams. These columns are vital in industries requiring liquid purification or solvent recovery, including chemical, petrochemical, oil & gas, and wastewater treatment sectors.

Each column is configured based on process requirements and fluid composition, and is available in two main designs: Tray Columns and Packed Columns.

Tray columns (also known as plate columns) are among the most widely used mass transfer devices in industrial separation. The number of trays and stages is precisely determined based on required separation efficiency and product purity.

Types of Trays Offered:

• Sieve Tray

• Bubble Cap Tray

• Moving Valve Tray

• Fixed Valve Tray

Key Benefits:

• Modular construction for easier maintenance

• Can be partially replaced with packing to debottleneck capacity

• Designed for excellent vapor-liquid contact

Material of Construction (MOC):

• All Stainless Steel (SS304 / SS316)

Packed columns provide high surface area for enhanced vapor-liquid interaction, resulting in greater separation efficiency per unit height compared to tray columns. Ideal for processes requiring compact column design and low-pressure drop.

Internal Components:

1. Mist Eliminator (Demister Pad)

   • Knitted wire mesh pad ensures 99%+ droplet separation down to 5 microns

   • Low-pressure drop (approx. 25 mm WC)

   • Maintenance-free and easy to install

2. Liquid Distributor

   • Ensures uniform liquid distribution across the packed bed

   • Prevents maldistribution, flooding, and inefficient mass transfer

3. Bed Limiter

   • Prevents displacement or fluidization of packing under high vapor load

   • Mounted on top of the packing layer

4. Packing Options

   • Random Packing: Metal/Plastic types (e.g., Raschig rings, Pall rings)

     • Maximizes surface-to-volume ratio, minimizes pressure drop

   • Structured Packing: Corrugated, honeycomb-type shapes

     • Precisely engineered to allow maximum surface area with low resistance

     • Suitable for high-efficiency, low-pressure operations

5. Packing Support Plate

   • Supports the weight of the packed bed

   • Designed with large open area to maintain uniform liquid and vapor flow

   • Prevents flooding and ensures mechanical integrity

Material of Construction (MOC):

• All Stainless Steel (SS304 / SS316)

• PP (Polypropylene) – for specific chemical resistance needs

• Removal of volatile hydrocarbons and chlorinated solvents

• Water purification and effluent treatment

• Solvent recovery systems

• Chemical process stripping and regeneration units

• Tailored design with tray or packed configuration

• High VOC removal efficiency

• Engineered internals for optimal gas-liquid contact

• Low maintenance and robust construction

• Available in wide material choices for corrosive or high-temperature services
