Water-Sealed Gas Holder

How It Works

A water-sealed gas holder is a storage system for gases, consisting of a deep water tank and a closed vessel that rises or falls based on gas volume. It absorbs fluctuations in gas supply and demand by allowing the gas tank to move up or down as gas enters or leaves the system. The water at the bottom forms a continuous seal that prevents gas leakage while maintaining stable storage conditions.

Key Features

• Water Seal – Prevents gas leakage by creating a reliable liquid barrier.
• Variable Storage Capacity – Accommodates changing gas volumes by allowing the holder to rise and fall.
• Pressure Regulation – Helps maintain a consistent gas supply pressure.
• Simple and Reliable Design – Proven technology with long operational life.
• Low Maintenance – Robust construction suitable for continuous industrial operation.

Common Use

• Storage of natural gas.
• Storage of town gas.
• Storage of industrial gases.
• Gas distribution facilities and utility plants.
• Industrial manufacturing processes requiring temporary gas storage.

Construction Materials

• Water Tanks – Typically made of wood, brick, cast iron, steel, or concrete.
• Gas Holder Vessel – Commonly fabricated from structural steel for strength and durability.
• Support Framework – Heavy-duty steel members designed to withstand operating loads.
• Protective Coatings – Corrosion-resistant coatings applied to improve service life.
