What does pressure-filled transferring refer to?

A method of storage of CNG
A transferring method using pressure differential
A type of compression technique
A technique for transporting vehicles

The correct answer is: A transferring method using pressure differential

Pressure-filled transferring refers to the process of moving compressed natural gas (CNG) from one container to another using the principle of pressure differential. This method takes advantage of the difference in pressure between the source container and the receiving container to facilitate the efficient transfer of gas. When the pressure in the source container is higher than that in the receiving container, the gas naturally flows from the higher-pressure area to the lower-pressure area, allowing for a smooth and controlled transfer. This approach is particularly important in the handling and distribution of CNG, as it ensures safety and maximizes the efficiency of the process. Understanding pressure-filled transferring is essential for CNG drivers and operators to ensure they manage the gas safely and effectively throughout its transport and storage.
