What is the purpose of vapor control systems?

The purpose of vapor control systems is primarily focused on reducing emissions of volatile organic compounds (VOCs) into the atmosphere. These systems are essential for environmental protection, as they capture and manage vapors that may otherwise escape during the loading and unloading processes of hazardous liquids, such as petroleum products. By recovering vapors, these systems help prevent air pollution and comply with environmental regulations aimed at minimizing the release of harmful substances.

Vapor control systems work by directing the vapors back into the cargo tank or utilizing them in a way that minimizes their release. This not only reduces the environmental impact but also contributes to safety by preventing the buildup of flammable vapors, which could pose explosion risks.

Other options may touch on related functionalities but do not specifically address the primary role of vapor control systems regarding emissions reduction, which is crucial for environmental protection and regulatory compliance.
