Gas cooling and dehydration units

Natural gas and associated petroleum gas are among the most important sources of energy and feedstock for chemical production, heating, ventilation, lighting, and the generation of heat and electricity.

Petroleum gas extracted from underground contains water, carbon dioxide, hydrogen sulfide, nitrogen, methane, ethane, and other components. These components can be used for various purposes only after the separation of moisture and individual constituents.

One method of gas separation is the dehydration of natural gas and associated petroleum gas by cooling, in order to obtain pipeline-quality gas and to separate gas mixtures.

This method is based on cooling of gas at constant pressure. During the process, excess moisture condenses and is removed, and the gas dew point is reduced.

Gas dehydration aimed to remove moisture from gases and gas mixtures precedes the transportation of natural gas through pipelines or low-temperature separation of gas mixtures into components.
