High Flow VSP Rings

High Flow VSP Rings are advanced plastic random packing elements designed to deliver superior gas–liquid contact efficiency with low pressure drop. Their unique inner-arc and open-window structure ensures excellent liquid distribution, high voidage, and robust mechanical strength. When manufactured in PVDF (Polyvinylidene Fluoride), these rings offer outstanding resistance to aggressive chemicals and higher temperature stability compared to conventional plastics, making them ideal for demanding applications.

Key Features

High chemical resistance – withstands acids, bases, and many solvents
Low pressure drop – ~15–45% lower vs. traditional pall rings
High void fraction (93–97%) – reduces flooding, increases throughput
Improved mass transfer efficiency – uniform gas & liquid distribution
Mechanical durability – suitable for tall packed beds

Advantages

Long service life in corrosive environments
Handles high gas and liquid loads before flooding
Reduced column height requirements due to higher efficiency
Easy installation and replacement compared to structured packings

Applications

Flue Gas Desulfurization (FGD): Effective removal of SO2 and other acidic gases in power plants and industrial boilers.
Chemical Processing: Used in absorption, stripping, and distillation towers for acids, bases, and solvents.
Air Pollution Control: Ideal for scrubbers handling HCI, HF, NH3, H2S, and other industrial emissions.
Water & Wastewater Treatment: Efficient in VOC stripping, odor control, and gas desorption systems.
Petrochemical & Fertilizer Plants: Suitable for high-capacity operations such as solvent recovery, brine treatment, and acid gas scrubbing.
Cooling & Gas Drying Towers: Provides high efficiency with low pressure drop in direct contact cooling and drying processes.
