What is a cascade storage system used for?

1. Storage in multiple cylinders

2. Storage in underground tanks

3. Storage in a single large tank

4. Storage in movable containers

The correct answer is: Storage in multiple cylinders

A cascade storage system is specifically designed for storing gases, such as compressed natural gas, within multiple cylinders. This method allows for efficient management and distribution of gas by utilizing a series of interconnected cylinders, where gas can flow from higher-pressure cylinders to lower-pressure ones as needed. This system enables optimization of storage capacity and ensures that the gas can be accessed readily for dispensing purposes. The approach of using multiple cylinders instead of a single large tank provides flexibility in gas management, safety, and the convenience of transport. Additionally, in a cascade system, each cylinder can be monitored, allowing for better tracking of gas levels and usage, which is crucial for operational efficiency. Other storage methods mentioned, such as underground tanks or a single large tank, do not offer the same level of versatility and immediate access that a cascade system provides. Identifying the requirement for a system like cascade storage is important for professionals working with compressed natural gas, as it facilitates consistent supply and efficient operational procedures in gas distribution.
