What Sets Van Air Systems Pipeline Dryers Apart in RNG Applications
Green energy is a term that is used more frequently nowadays, and for good reason.
So what economic and environmental advantages do Van Air Systems PLD Series Pipeline dryers afford that competitors lack?
Van Air Systems’ PLD (Pipeline Deliquescent) dryers stand out in “green energy” terms not because they’re branded as renewable technology, but because their core design eliminates energy consumption and emissions sources that most competing dehydration technologies require.
Here’s a clear breakdown of the economic + environmental advantages—and what competitors typically cannot match.
1. ZERO Energy Consumption
a. PLD dryers require no electricity and no fuel gas to operate
b. No heaters, compressors or controls
Why does this matter?
Many competing systems such as glycol/teg or regenerative desiccant dryers need
a. Heaters or boilers
b. Pumps and circulation systems
c. Control systems and instrumentation
So here, PLD has a very small operating energy footprint, while competitors will regularly consume energy.
2. Zero Emissions Operation
a. PLD Systems produce zero emissions during operation
b. No BTEX or hydrocarbon venting
Many competitors such as glycol dehydrators vent methane and other hazardous substances.
PLD is one of the very few systems that do no have any emissions, which is huge when talking about green energy sources.
3. NO METHANE LOSS
a. Many glycol systems vent methane during the dehydration process
b. PLD systems reduce the moisture and retain all gas in the pipeline.
Takeaway: More Gas and less emissions = win win.
4. No Purge Gas Losses
a. Many desiccant dryer competitors require purge gas
b. PLD dryers require zero purges.
No wasted gas, no extra energy needed, higher system efficiency.
5. Very low Maintenance
a. The PLD Dryer requires no moving parts
b. It has no valves or controls to worry about
Many competitors have pumps, heat exchangers, and valves to switch. PLD Dryers are known for their reliability, and durability. They can be installed virtually anywhere and have very little maintenance cost.
6. Ideal for Renewable Natural Gas (RNG) and remote energy systems
a. PLD dryers do not require power, so work perfectly for applications where power cannot be accessed.
b. Suitable for: Biogas, RNG upgrading, remote Pipeline wellheads, Off grid systems
Many competitors require electricity.
There are many competing technologies to the Van Air Systems PLD dryers. However, the main difference is the fact that PLD dryers offer zero emissions, require no electricity, and can be installed anywhere.
They are one of the easiest dryers to use available in the natural gas industry and require very minimal maintenance. Van Air Systems PLD dryers may be the most practical, reliable solution for natural gas drying without added complexity.
