What is the role of a vapor recovery system during LP gas handling?

A vapor recovery system plays a critical role in the handling of liquefied petroleum (LP) gas by capturing vapors that may be released during the transfer and storage processes. This system is designed to minimize emissions of volatile organic compounds (VOCs) into the atmosphere, which are not only harmful to the environment but can also pose health risks. By trapping these vapors, the recovery system ensures that they are returned to the storage tank or processed properly, rather than being released into the air.

This is particularly important in compliance with environmental regulations aimed at reducing air pollution. Capturing vapors improves environmental safety by decreasing the overall emissions associated with LP gas handling operations. Additionally, it can enhance the overall efficiency of the handling process as the recovered vapors can be reused, minimizing waste.

The other options do not accurately describe the function of a vapor recovery system. Enhancing fuel efficiency relates more to the ignition and combustion processes rather than vapor management. Increasing pressure in the tank pertains to the physical storage mechanisms but does not involve vapor recovery. Controlling the distribution of gas involves the movement and supply logistics of gas rather than the capture of emissions, which is the primary function of a vapor recovery system.
