Storage tanks
Storage tanks is nothing but tank which used for storage of liquid or slurry or Gas some.
There several types of storage tanks.
types of storage tanks
Fixed roof Storage tanks
floating roof Storage tanks
cone roof Storage tanks
Fixed Roof Tanks
Fixed roof tanks are storage tanks that have a fixed, non-moving roof. These tanks are commonly used for storing liquids that do not require any ventilation or agitation, such as water or some chemicals.
Advantages of fixed roof Storage tanks
- Simple design and construction
- Low cost
- Suitable for storing liquids with low volatility
Disadvantages of fixed roof Storage tanks
- Can experience overpressure or vacuum conditions due to thermal expansion or contraction of stored liquids
- Cannot handle liquids that emit gases or fumes
Floating Roof Tanks
Floating roof tanks are storage tanks that have a roof that floats on top of the liquid being stored. These tanks are commonly used for storing liquids that emit gases or fumes, such as petroleum products or chemicals.
Advantages of floating roof Storage tanks.
- Reduces emissions and prevents evaporation
- Suitable for storing liquids with high volatility
- Can handle thermal expansion and contraction of stored liquids
Disadvantages of floating roof Storage tanks.
- More expensive than fixed roof tanks
- Requires maintenance of the floating roof mechanism
- Limited to liquids that do not solidify or crystallize
Cone Roof Tanks
Cone roof tanks are storage tanks that have a cone-shaped roof that is attached to the top of the tank. These tanks are commonly used for storing liquids that are flammable or volatile, such as gasoline or diesel.
Advantages:
- Provides additional support to the tank
- Reduces the buildup of vapors
- Suitable for storing liquids with high volatility
Disadvantages:
- More expensive than fixed roof tanks
- Requires additional reinforcement to handle wind or seismic loads
- Limited to a maximum roof slope angle to prevent roof collapse
- Open Top Tanks: Open top tanks are storage tanks that have an open top instead of a roof. These tanks are commonly used for storing liquids that require frequent agitation or mixing, such as chemicals or wastewater.
Advantages:
- Easy to fill and empty
- Suitable for liquids that require frequent agitation or mixing
- Can be used for temporary storage
Disadvantages:
- Not suitable for storing liquids that emit gases or fumes
- Limited to liquids that do not require a roof to maintain their properties
- Requires protection from weather and environmental conditions
- Pressure Tanks: Pressure tanks are storage tanks that are designed to store liquids or gases at a higher pressure than the surrounding environment. These tanks are commonly used for storing compressed gases or liquids that require a higher pressure to remain in a liquid state.
Advantages:
- Allows for storage of liquids or gases at a higher pressure than atmospheric pressure
- Can be made from various materials, including steel, aluminum, or composite materials
- Suitable for storing liquids or gases that require pressure to maintain their properties
Disadvantages:
- More expensive than atmospheric storage tanks
- Requires additional safety measures and equipment to prevent overpressure or vacuum conditions
- Limited to liquids or gases that can be stored at a specific pressure and temperature range
types of storage tanks based on their construction, along with their advantages and disadvantages
| Type of Storage Tank | Construction | Advantages | Disadvantages |
|---|---|---|---|
| Fixed Roof Tanks | Non-moving roof | Simple design and construction, low cost, suitable for low volatility liquids | Can experience overpressure or vacuum conditions, cannot handle gases or fumes |
| Floating Roof Tanks | Roof that floats on top of the liquid | Reduces emissions and prevents evaporation, suitable for high volatility liquids, can handle thermal expansion and contraction | More expensive than fixed roof tanks, requires maintenance, limited to non-solidifying liquids |
| Cone Roof Tanks | Cone-shaped roof attached to the top of the tank | Provides additional support and reduces vapors, suitable for high volatility liquids | More expensive than fixed roof tanks, requires additional reinforcement, limited to maximum roof slope angle |
| Open Top Tanks | Open top instead of a roof | Easy to fill and empty, suitable for frequent agitation or mixing, can be used for temporary storage | Not suitable for gases or fumes, limited to liquids that don’t require a roof, requires protection from weather |
| Pressure Tanks | Designed to store liquids or gases at a higher pressure than the surrounding environment | Allows for storage of liquids or gases at higher pressure, can be made from various materials, suitable for liquids or gases that require pressure | More expensive than atmospheric storage tanks, requires additional safety measures, limited to specific pressure and temperature range |
