…an introduction
BIOGAS requires upgrading to be used as CNG or LNG Vehicle Fuel
Raw Biogas Characteristics
• Common: 2 – 8 inches of water column
• Municipal applications: up to 15 inches
Major Constituents:
Renewable Natural Gas
• Upgraded biogas can be interchangeable with natural gas

How Does an
Upgrading Unit
A Simple Concept
Biogas is primarily methane (CH4) and carbon dioxide (CO2)
Water under pressure can be used to separate these two gases
through their different solubility in H2O. This happens in the
Greenlane Scrubbing Tower.
Water Regeneration
• The Greenlane systems recycle water! Only a small amount of water is
added compared to the recirculation rates. This make-up water helps
keep the system clean, with a similar amount of water blown-down.
•Water from the scrubber is sent to a Flashing Tower to partially
depressurize, so the small amount of absorbed methane can be removed
from the water, enhancing methane recovery
• The water is then sent to the Stripping Tower that removes the gases
absorbed in the water
• Once stripped, the water is re-used to clean more Biogas!
How Does the Greenlane
Water Scrubber work?
The raw biogas is compressed, then fed to a ‘scrubbing’ tower where it is
contacted with water. CO2, H2S, siloxanes and other trace contaminants
are preferentially absorbed by the water.
Absorbed methane is ‘flashed’ off, in a tower at a lower pressure and
recovered by returning it to the start of the process.
Product gas is further purified by a drier, before being analyzed and
delivered to the customer.
Greenlane Water Scrubbing
Technology in Focus
Water used as the scrubbing agent
Water scrubbing process upgrades raw biogas to vehicle fuel or pipeline
standards efficiently, and with less impact on the environment Biomethane
quality exceeds recognized international vehicle fuel standards and natural gas
quality specifications.
Full Automation
The entire plant is controlled by a PLC that monitors all parameters required
for safe and productive operation
Hydrogen Sulphide
Greenlane’s innovative, patented “polishing” process is proven to reduce
biomethane H2S carryover to typically less than 1 ppm in the biomethane.
Track Record
Greenlane has been building water scrubbing systems for over 20 Years, with
over 80 Systems Worldwide.
High Availability Biomethane Systems
Greenlane biomethane plants have the highest availability in the market.
Twenty years of experience and seven generations of design have
translated into a set of standard systems with no surprises.
Issues around biogas liquids handling, contaminant fouling, biogas
composition variations, etc., have been solved.
Repeating proven designs with reliable
components controlled by verified
software is our recipe for eliminating
operational risk.
Remote monitoring and management
ensure plants perform as expected.

Kanuka combines simplicity, low
cost and compactness to make it
a sharply competitive proposition
up to 300 Nm3/hr.
Housed in a 20ft container and
offering the patent pending and
disruptive Water Flooded Screw
technology, enables
simplification of the biogas
upgrading process and
significant cost savings.
Rimu offers over twice the
capacity of Kanuka, with
nominal flow of 800 Nm3/hr.
This particular size is the most
proven in upgrading. It is a
simple design with
excellent reliability and high
uptime availability (95% 98%).
Matai fits the requirement for mid-range
capacity up to 1200 Nm3/hr while retaining
the same benefits of efficiency and
economy of scale as the larger Totara
Totara & Totara+ are the largest models
currently offered with capacities of 2000 &
2500 Nm3/hr respectively. Greenlane have
supplied or have orders for 32 of these plants
around the world.
The units are offered in purpose built
enclosures to provide an elegant and highly
maintainable solution.
Totara’s efficiency and methane yield are the
best available. Like the Matai, the Totara units
are generally supplied in purpose built
enclosures, with the majority of Totara+
supplied non-containerised in client supplied

How do I Know if I
Have a Project?
… determining project feasibility
Assessing Feasibility
Vehicle Fuel vs Other Uses
© 2010 Canada Gas Association
Vehicle Fuel vs Other Uses
• Higher efficiency = More gas = More
revenue. ($)
• Most farms have several vehicles (Utility
vehicles, milk trucks, pick-up trucks) for
essential farm operations with Diesel
being their largest expense.
Assessing Feasibility for CNG
In order to do a feasibility study we must analyze the following variables:
CNG (Diesel) price: 7.41 DGE per MMBTU. 1 gallon of diesel contains in
average 0.135 MMBTUs. The US Energy Information Administration (EIA)
posts an diesel price forecast data per region. Pick the low oil price case
as it is the most conservative.
Assessing Feasibility for CNG
You also must reduce from the revenue streams the operational costs associated
with converting to vehicle fuel:
Heating Costs of Digester
Biogas Upgrading Costs
CNG Compression Costs
Additional Labor
Utility consumption of the various pieces of equipment.
Capital Expense, Financial Costs and Development and Permitting Expenses must
also be considered when determining feasibility.
After modeling both scenarios (High and Low Diesel pricing). If the low oil price
Diesel case gives back an IRR of 18-25% the project is feasible.
