Don’t Get Caught in the Rush!

Our lead time tends to get longer from September through December. This is because of the high volume of natural gas vessels purchased during these months. We recommend that you place your order in the early part of the year to avoid a long delivery time and having to wait due to the rush.

Natural Gas Dryer Sizing & Desiccant Tablet Selection

Natural Gas Dryer Sizing & Desiccant Tablet Selection The chart below shows Natural Gas Pipeline Dryer (PLD) sizes with flow capacities & pressure ranges. From this chart, pick the line which is your lowest operating pressure and read down to the capacity that matches or exceeds your flow rate.  Then you can go to the left of the chart and pick the corresponding model group. Now select the model that meets or exceeds your maximum operating pressure. Maximum Working Pressure: 	280 PSIG = Model Suffix 2.8 	720 PSIG = Model Suffix 7.2 	1450 PSIG = Model Suffix 14.5 	Example: PLD8-7.2 is a Pipeline Dryer 8” diameter vessel with a 720 psig MWPThe charts below show sizes with flow capacities & pressure ranges. From these charts, pick the line which is your lowest operating pressure and read down to the capacity that matches or exceeds your flow rate. Then you can go to the left of the chart and pick the corresponding model group. Now select the model that meets or exceeds your maximum operating pressure.

Example: Maximum Working Pressure:

  • 280 PSIG = Model Suffix 2.8

Desiccant Tablet Selection

The water chart below shows the saturated water vapor content in Lbs/MMSCF for natural gas. With one of our 3 GasDry Desiccants, you can lower the water content to a level suitable for your Fuel Gas Dryer or Instrument Gas Dryer requirements.

  • GasDry Prime 55% RH
  • GasDry Peak 33% RH**
  • GasDry Max 13% RH

As an example, GasDry Prime provides a 55% RH level. So, looking at the chart for natural gas at 500 psig, 75°F, the water content is 48 lbs water/mmscf. You would take 48 lbs water x .55 (55% RH) = 26.4 lbs water/mmscf on the gas after flowing through the gas dryer filled with GasDry prime.

The same holds for Peak or Max. Just multiply the water content by the corresponding RH level to get a water content figure after flowing through the desiccant tablets.

For flows or vessels larger than listed please contact us. We have several Natural Gas Pipeline Dryers above 36″ diameter. Also, we can place dryers in series or parallel arrangements to suit your operating conditions.

**GasDry Peak not recommended over 80°F.
