Electric Heating Systems for Liquid-Gas Vaporization

Electric Circulation Heater

Hydrocarbon and non-hydrocarbon based gas products are transported and stored at low temperatures. The most common examples of liquified gasses are liquified natural gas, butane, propane, nitrogen, and oxygen. In liquid form gases are more convenient and efficient to transport, however once at their destination, they must be changed back to the gaseous state.

There are many ways to accommodate the phase change from liquid to gas and picking the best option is dependent on many criteria including plant location, climate conditions, available energy sources, and infrastructure available.

Transitioning from liquid phase to gas phase is a gradual process usually taking place at higher pressures, through several containment vessels, heat exchangers or heating coils which slowly warms the liquified gas.

Some thermal heat exchanging systems use fluids such as hot oil, hot water or a glycol-water solution to efficiently transfer heat to the liquified gas.
