Dry-seal gas holder
- Storage / Gasholder
Structure and Principle
This gas holder is composed mainly of a steel bottom plate, side plates, a roof plate, and an internal piston. These components are connected with each other with special seal film to form an airtight chamber. Gas is stored in this chamber under a fixed pressure. Free from friction, the piston moves up and down as the sealing film change its forms. Generally, the pressure of the gas stored in the chamber is 6 kPa or less. For a gas holder having a capacity of 10,000 m3 or more, the side plates support the structure.
- Capable of storing water-soluble gas
- Not using water, oil, or other liquid in the seal, the dry-seal holder can store water-soluble gas. Also, the gas holder can retain gas containing fine solids such as dust.
- Anti-seismic structure
- There have been no cases of gas leakage caused by damage to the gas holder due to an earthquake.
- Operable for over 40 years
- Highly durable and maintainable, our dry-seal gas holder can work for over 40 years.
