Natural Gas Processing Bio-Reactor System
The Natural Gas Bio-Reactor System has been designed to remove siloxane, hydrogen sulfide, Thiols
(Mercaptans) and Nitrogen related compounds from the natural gas well. The carbon bed filter system
entraps all the unwanted natural gas contaminates while allowing all the methane gas to escape but a very
small percentage 0.0003%.
After the carbon bed entraps the raw natural gas contaminates they are further delivered by rotation to a
water bath area which is used to remove the natural gas contaminates from the carbon filter beds. This is a
continual carbon bed washing operation, so future removal of the carbon bed filter is never required and the
carbon may be in the active state for up to twenty years. The wash bath process stage is an area where the
natural gas contaminates are subjected to a very specific grouped set of microbes to digest contaminates as
a nutritional food source.
The natural gas flow passes into the carbon bed filtration system and emerges as high quality methane gas,
free of compromising compounds to the line compression system for transportation to the natural gas
processing unit. By removing the sulfide, siloxane, thiols and any nitrogen compounds prior to the
transportation line it lessens any associated wear on post treatment components such as gas compressors,
monitors and many of the natural gas processing treating units.
The Bio-Reactor system is fabricated using stainless steel in the areas of direct exposure to the corrosive
contaminates. The natural gas enters the first of many granulated carbon chambers where contaminates are
trapped, after the contaminates are trapped the processed methane continues to exit the filtration system to
the line compression station.
In the second phase of the filtration system, the carbon bed towers are washed. As the water bath is
introduced into the stainless steel module the contaminates trapped in the granulated carbon bed are
washed and the contaminates or nutrients are offered to the selected microbes as a food source. These
microbes continually digest the contaminates. The only byproduct of the digestion is water and CO2.
The microbial activity creates no sludge and requires no special wastewater treatment. The microbial colony
must be replenished twelve times per year. The cost associated with the microbial change out is $150.00 per
pound. Typical microbial amounts on a large 20,000 cfm is two pounds. They are in a dry powder form and
have a shelf life of up to five years. Changing the microbes requires less than one hour of employee time.
The filtration system operates with either pressure from the process line (4 to 8”w.g.) or a forced draft blower
and requires no fuel and only minimal amounts of electricity to operate the blower (if required). The filtration
system requires no down time, other than normal mechanical maintenance on the blower, should a blower
system be required along with a small pump system.
The Bio-Filtration System is able to eliminate the Hydrogen Sulfide, Siloxane, Thiols (Mercaptans) and
Nitrogen compound by least greater than 98%. Guaranteeing pure processed methane providing endless
benefits to the owner/operator including reduced processing increased maintenance intervals and longer
For every emission application the operation parameters are defined including the process temperature,
microbial amount, differential gas pressure between the intake and outlet, and service time for adding the
microbes in order to ensure that the system operates at optimal efficiency. The microbial wash basin is
equipped with inspection windows to quickly verify the fluid level and the state of cleanliness.
The all system parameters may be controlled via a programmable logic controller (PLC), if a facility requires
a more controlled system. In addition, it is very easy to integrate the ability to monitor and modify the
operating parameters via Internet.
The carbon bed microbial natural gas bio reactor system offers a low maintenance, low cost solution to the
removal of natural gas contaminates. With superior efficiencies and simple design while offering years of
reliable service at a small percentage of comparative equipment costs.
