The solids from the waste water treatment process are sent to Digesters, which break down the solids to produce Anaerobic Digester Gas. The gas typically contains 60% methane, a recoverable and renewable source of energy. Most of the remaining gas is CO_2, a potential source for fertilizer.

It’s is a valuable source of “GREEN ENERGY”; however, it’s hot (90 to 110 ⁰F), humid (80-100 %) and dirty; and, its produced at a very low pressure (8” – 20” WC).

Untreated, the gas is not suitable for power generation, because, it damages piping & equipment coming in contact with it. Its most troublesome contaminants are – Moisture, Siloxanes and Sulfur compounds. The gas shall be cleaned, dried & compressed for a gen-set, turbine or boiler. 

The gas recovery eliminates harmful emissions to atmosphere, provides a renewable domestic energy source, and, earns EPA credits for WWTP.

For proper selection and sizing of equipment, consult factory. PIONEER systems are available with or without PLC (AB/ SIEMENS/ GE), with your choice of controls. Non-standard equipment is our specialty.

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.

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.

Gas is treated and filtered by a scrubber before compression, which raises its temperature, and lowers its relative humidity. Compressed gas flows thru Moisture Evaporator and After-Cooler, where gas is cooled to near ambient temperature.

From After-Cooler gas flows thru Gas-Gas Heat Exchanger (Economizer) and Gas to Refrigerant / Glycol Heat Exchanger, where its temperature is lowered down to 40^oF (4^oC). Cooling of gas condenses vapors, which are separated and removed in Cold Coalescing filter for maximum separation.

Cold gas then flows thru Gas-Gas Heat Exchanger, where it's re-heated to 70^oF to 90^oF (21^oC to 32^oC), as it pre-cools incoming gas. System includes a Back Pressure Regulator to control gas flow & pressure at system outlet, and return excess gas to a storage/ flare.

Gas is filtered by an inlet scrubber before the gas to refrigerant (or glycol) heat exchanger to remove entrained particulates & liquids; and, to keep heat exchangers clean. The gas to refrigerant heat exchanger cools gas to 40^oF before its compressed, which protects blower/compressor.

Gas compression raises the gas temperature, and lowers its relative humidity; which is desirable for most applications. Upon compression, the gas flows thru Moisture Evaporator (optional); where the gas is cooled and the moisture is evaporated. The system includes a "Back Pressure Control Valve" to control gas flow & pressure to the system outlet and return the excess gas. It's available as a factory integrated system; or, in two parts – Gas to Refrigerant Heat Exchanger and balance of the system.

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