What type of systems is used in tankers to control vapor emissions?

Vapor control systems are designed specifically for managing and reducing vapor emissions from tankers during loading and unloading operations. These systems work by capturing vapors that would otherwise escape into the atmosphere, thus preventing air pollution and reducing the risk of ignition from flammable vapors.

The effectiveness of vapor control systems is crucial for compliance with environmental regulations and for ensuring safety on and around the vessel. They generally consist of various components, including vapor recovery units that can either condense vapors back into liquid form for storage or process them in a way that minimizes emissions.

In contrast, vacuum systems may be used for other purposes, such as loading cargo, but they do not specifically target vapor emission control. Pressure release systems primarily manage internal pressures within tanks during operations but do not actively control vapor emissions. Condenser systems are involved in cooling processes and recovering liquids from vapor but are not solely focused on vapor management in the way vapor control systems are. Therefore, vapor control systems are recognized as the most effective and dedicated solution for minimizing vapor emissions in tanker operations.
