Another requirement for a vaporizer in a propane system is to:

• A. To increase tank capacity
• B. To decrease tank capacity
• C. To decrease tank pressure
• D. To increase tank pressure

Answer: (B)

The main idea is how a vaporizer affects propane gas delivery: its job is to provide enough heat to turn liquid propane into gas so the system can meet demand at the correct downstream pressure. The vaporizer doesn’t change how much liquid can be stored in the tank (tank capacity) and it doesn’t directly set the tank’s pressure. Tank capacity is fixed by the tank size, and tank pressure is governed by propane’s vapor pressure at the tank’s temperature; the downstream regulator controls the pressure delivered to appliances. So the point of a vaporizer is to ensure adequate vaporization for flow, not to alter the tank’s capacity. If the option says the vaporizer’s requirement is to decrease tank capacity, that isn’t how a vaporizer functions. The key takeaway is that vaporization (via heat input) enables gas delivery, while capacity and pressure are managed by the tank design and the regulators in the system.
