Compressed Air Gas Drying

Desiccants are commonly used for drying compressed air. Moisture in a compressed air system can cause serious corrosion and wear of many types of equipment and can cause instruments and controls to malfunction. Drying of instrument air to a dewpoint of -40°F (-40°C) prevents condensation or freeze-up in the instrument control lines. Dry air prevents rusting of the air lines, which produces abrasive impurities and causes excessive wear on tools. Desiccant drying effectively solves these problems, while also removing dirt and oil.

Since the drying and reactivation occurs in separate sealed compartments, solid tower systems are especially effective for dehumidifying compressed air and pressurized process gases. They can be designed to achieve dew-points as low as -60°F (-51°C) over a wide range of capacities.

Drying and cleaning of industrial gases or fuels, such as natural gas, is done before storage underground to ensure that valves and transmission lines do not freeze from condensed moisture during very cold weather. Other gases, such as liquid oxygen, hydrogen, and nitrogen, must also have a high degree of dryness.

Renewable Energy 101

Renewable energy is energy that is generated from sunlight, rain, tides, geothermal heat and wind. These sources are naturally and constantly replenished, which is why they are deemed as renewable. The usage of renewable energy sources is very important when considering the sustainability of the existing energy usage of the world. While there is currently an abundance of non-renewable energy sources, such as nuclear fuels, these energy sources are depleting. In addition to being a non-renewable supply, the non-renewable energy sources release emissions into the air, which has an adverse effect on the environment.
