STORAGE OF LOW PRESSURE GASES
VARIABLE SIZE STORAGE
The traditional method of storing low-pressure gases is in a water-sealed Gas Holder (or Gasometer). Another LP storage vessel is the 'Piston Type' gas-holder.
1. THE WATER-SEALED, TELESCOPING GASOMETER
This vessel is constructed in sections that 'Telescope' up and down as the quantity of contained gas changes. Water (or oil) seals are fitted between the telescoping sections with sufficient head pressure to prevent gas blowing out of the seals. The gas pressure is governed by the weight of the telescoping sections.
2. THE PISTON TYPE GASOMETER
This gas holder contains a weighted piston with seals fitted between it and the vessel shell. Again, the quantity of gas governs the position of the piston. The pressure of the gas depends on the weight of the piston.
