The gas pressure needed depends on the device using the gas; add to it the pressure losses thur cleaning equipment, piping, valves ect.

We recommend that the Desiccant should be changed once a year.

Our units can go upto 3 years with out needing the change the desiccant. This is all dependent on your compressor and how old it is, if it has oil blow by, ect…

The best way to have an idea on when you should change the desiccant is to have a dew point meter on your unit. When you track a pressure drop on the dew point meter from the last time the desiccant was installed.

Contact us if this does not Answer your question.

Biogas composition from a landfill or waterwater treatment plant (digestar gas) can change quickly. Therefore, you should test a sample of your biogas once every six months.

A higher pressure drop means a loss of energy, which causes a compressor to use more power.

However, typically the above fact is overlooked; and, a customer changes filter element when the pressure down stream becomes insufficient. In other words, it depends on customer's tolerance for the pressure drop.

To set controls you may use the following guide, unless customer specifies a different requirement -

A. For 90 to 250 PSIG range operating pressure – Use 3 PSIG for changing all filter elements.

B. For 40 to 90 PSIG range operating pressure – Use 2 PSIG for changing all filter elements.

C. For 10 to 40 PSIG range operating pressure – Use 1 PSIG for changing all filter elements.

D. For 3 to 10 PSIG operating pressure – Use 0.5 PSIG for changing all filter elements.

E. For 0 to 3 PSIG operating pressure – Use 0.1 to 0.2 PSIG for changing all filter elements.

F. For 250 to 1000 PSIG range operating pressure – Use 5 PSIG for changing all filters.

G. For over 1000 PSIG range operating pressure – Use 10 PSIG for changing all filters.

The key corrosive components in Biogas are: Moisture, Siloxanes & Sulfides (h₂S & So₂).

Methane (CH₄) is colorless, oderless and flammable gas which burns in air/oxygen (O₂) with a blue flame and it is also the main hydrocarbon which makes up natural gas. Methane is a reliable and renewable fuel source the if not collected, goes to waste. Methane is now being used as a fuel to power cars and trucks.

Methane burns cleanly only producting carbon dioxide (CO₂) and water (H₂O) as by-products of its combustion [CH₄ + 2O₂ - > CO2 + 2H₂O].

Q.  Where do I find the Serial number to my Pioneer Air Systems, Inc. unit.
A. You can locate the serial number from the sticker plate.

Q.  What deos the serial number sticker plate look like?
A. 12345-000000 – The first part is all numbers. example: 60000-    The last half will have letters and numbers. example: -A20J00

Example:

At the minimum, the gas should be tested for – Methane, Oxygen, Nitrogen, Carbon Monoxide, Carbon Dioxide, Hydrogen, Siloxanes & Sulfides (H₂S & SO₂)

A typicl blower can provide up to 15 PSIG gas pressure, whitch is usually sufficient for most low pressure devices e.g Boilers & IC Engines.

A gas compressor is usually required for devices requiring a higher gas pressure e.g. Micro-turbines & Turbines.

As the pipeline quality natural gas with a moisture content of 7 lbs/MMSCF is compressed to 3600 PSIG it has a dewpoint of 52°F/11°C. When compressed natural gas (CNG) equipment is subjected to temperatures below 52°F/11°C, the moisture begins to condense. When the temperature falls below 32°F/0°C, the moisture freezes, causing malfunction of equipment and interrupting CNG delivery.

When mixed with moisture, impurities in natural gas, especially H2S and CO2, form a corrosive mixture that destroys equipment. The presence of moisture also affects accurate delivery measurement.

The Energy Policy Act of 1992 requires federal fleets to begin purchasing alternative fuel vehicles (AFV’s) in the fiscal year 1993. The following table is a summary of requirements for federal and state fleets, alternative fuel providers, and private and municipal fleets.

AFV Requirements

You should remove Siloxanes because, Siloxanes damage Internal Combustion (IC) Engines, Micro turbines, Boilers and SCR. When heated, Siloxanes form a sand like white powder. This powder can coat components and cause seizure or a failure of the moving components.

As the water in the cooling tower evaporates, most solid contaminants in the water do not evaporate. The concentration of these contaminants accumulates rapidly and will undermine the cooling capacity of the system. In addition, airborne impurities and biological contaminants are introduced into the recirculating water.

To control potential contaminants, a water treatment program must be employed. In most cases, use of a Pioneer Kleen-Water Filter and a simple bleed-off at the Pioneer filter may be adequate for control of scale and corrosion. However, biological contamination can be controlled only through the use of biocides, and such treatment should be initiated at system start-up and continued regularly thereafter.

For specific recommendations on water treatment, consult a local water treatment specialist.
