What
is "waste-to-energy"?
Waste-to-energy
facilities produce clean, renewable energy through the combustion of
municipal solid waste in specially designed power plants equipped with the
most modern pollution control equipment to clean emissions. Trash volume
is reduced by 90% and the remaining residue is regularly tested and
consistently meets strict EPA standards allowing reuse or disposal in
landfills. There are 89 waste-to-energy plants operating in 27 states
managing about 13 percent of America's trash, or about 95,000 tons each
day. Waste-to-energy facilities generate about 2,500 megawatts of
electricity to meet the power needs of nearly 2.3 million homes, and the
facilities serve the trash disposal needs of more than 36 million people.
The $10 billion waste-to-energy industry employs more than 6,000 American
workers with annual wages in excess of $400 million.
How
does waste-to-energy reduce Greenhouse Gases emitted into the atmosphere?
The
use of waste-to-energy technology prevents the release of forty million
metric tons of greenhouse gases in the form of carbon dioxide equivalents
that otherwise would be released into the atmosphere on an annual basis,
according to an analysis developed by the U.S. Environmental Protection
Agency and the Integrated Waste Services Association (IWSA) using EPA's
Decision Support Tool program. Annual reporting by IWSA to the U.S.
Department of Energy's Voluntary Reporting of Greenhouse Gases Program
confirms that waste-to-energy also prevents the release each year of
nearly 24,000 tons of nitrogen oxides and 2.6 million tons of volatile
organic compounds from entering the atmosphere.
America's
waste-to-energy facilities dispose of trash, and are an alternative to
land disposal that releases methane (a potent greenhouse gas) as trash
decomposes. Waste-to-energy also produces electricity, lessening reliance
on fossil fuel power plants that release carbon dioxide, another
greenhouse gas, into the atmosphere when coal or oil are burned. Operation
of waste-to-energy plants avoid the release of methane that otherwise
would be emitted when trash decomposes, and the release of CO2 that would
be emitted from generating electricity from fossil fuels.
In
addition to the analysis using EPA's Decision Support Tool, and eight
years of reporting by the IWSA to the U.S. Department of Energy, a
detailed, project analysis of a facility's contribution to solving the
threat of global warming has been completed for a 1500-ton-per-day
waste-to-energy facility in the northeast. Researchers used information
regarding alternative landfill disposal, plant emissions, trash
composition and other plant-specific data and analyzed the information
using the EPA Decision Support Tool. The study determined that about
270,000 tons of carbon dioxide equivalent emissions are avoided annually
because of this one plant's operations. Company officials currently are
talking to greenhouse gas credit brokers about marketing the reductions to
buyers of GHG credits.

1The
Impact of Municipal Solid Waste Management on Greenhouse Gas Emissions In
the United States, by K.A. Weitz, Research Triangle Institute, S.A.
Thorneloe, U.S. Environmental Protection Agency, and M. Zannes, IWSA, 2001
discusses the overall contribution, including waste-to-energy's part, in
reduction of greenhouse gas emissions from proper solid waste management
practices. The analysis concludes that emissions of 11 million metric tons
carbon equivalent was avoided on an annual basis by the use of
waste-to-energy technology.

conversion of carbon equivalent to CO2
equivalent is based on the ration of the molecular weight of carbon to the
molecular weight of CO2, or a factor of 3.67.

United States.

Flare
Gas Recovery, Vapor Recovery, Waste to Energy and Vapor Recovery Units
recover valuable "waste" or vented fuels that can be used to
provide fuel for an onsite power generation plant. Our
waste-to-energy and waste to fuel systems significantly or entirely,
reduces your facility's emissions (such as
NOx
,
SOx, H2S, CO
, CO2 and other Hazardous Air Pollutants/Greenhouse Gases) and convert
these valuable emissions from an environmental problem into a new cash
revenue stream and profit center.
Flare
gas recovery and vapor recovery units can be located in hundreds of
applications and locations. At a Wastewaster Treatment System (or
Publicly Owned Treatment Works - "POTW") gases from the facility
can be captured from the anaerobic digesters, and manifolded/piped to one
of our onsite power generation plants, and make, essentially,
"free" electricity for your facility's use. These
associated "biogases" that are generated
from municipally owned landfills or wastewater treatment plants have low
btu content or heating values, ranging around 550-650 btu's.
This makes them
unsuitable for use in natural gas applications. When burned as fuel to
generate electricity, however, these gases become a valuable source of
"renewable" power and energy for the facility's use or resale to
the electric grid.
Additionally,
if heat (steam and/or hot water) is required, we will incorporate our
cogeneration or trigeneration system into the project and provide some, or
all, of your hot water/steam requirements. Similarly, at crude oil
refineries, gas processing plants, exploration and production sites, and
gasoline storage/tank farm site, we convert your facility's "waste
fuel" and environmental liabilities into profitable,
environmentally-friendly solutions.
Our
Flare Gas Recovery and Vapor Recovery units that are designed and
engineered for these specific applications. It is important to note
that there are many internal combustion engines or combustion turbines
that are NOT suited for these applications. Our systems are
engineered precisely for your facility's application, and our engineers
know the engines and turbines that will work as well as those that don't.
More importantly, we are vendor and supplier neutral! Our only
concerns are for the optimum system solution
for your company, and we look past brand names and sales propaganda to
determine the optimum system, which may incorporate either one or more;
gas engine genset(s) or gas turbine genset(s), in cogeneration or
trigeneration mode - in trigeneration mode, we incorporate absorption
chillers to make chilled water for process or air-conditioning, fuel
gas conditioning equipment and gas compressor(s).
Our
turn-key systems includes design, engineering, permitting, project
management, commissioning, as well as financing for our qualified
customers. Additionally, we may be interested in owning and operating the
flare gas recovery or vapor recovery units. For these applications, there
is no investment required from the customer.
For
more information, please provide us with the following information about
the flare gas or vapor:
-
Type
of gas being flared or vented (methane, bio-gas, landfill, etc.).
-
Chromatograph
Fuel/Gas analysis which provides us with the btu's (heating value) and
the composition of the gas and its' impurities such as methane (and
the percentage of methane), soloxanes, carbon dioxide, hydrogen,
hydrogen sulfide, and any other hydrocarbons.

* Waste Heat Recovery
Many
industrial processes generate large amounts of waste energy that simply
pass out of plant stacks and into the atmosphere or are otherwise lost.
Most industrial waste heat streams are liquid, gaseous, or a combination
of the two and have temperatures from slightly above ambient to over 2000
degrees F. Stack exhaust losses are inherent in all fuel-fired processes
and increase with the exhaust temperature and the amount of excess air the
exhaust contains. At stack gas temperatures greater than 1000 degrees F,
the heat going up the stack is likely to be the single biggest loss in the
process. Above 1800 degrees F, stack losses will consume at least half of
the total fuel input to the process. Yet, the energy that is recovered
from waste heat streams could displace part or all of the energy input
needs for a unit operation within a plant. Therefore, waste heat recovery
offers a great opportunity to productively use this energy, reducing
overall plant energy consumption and greenhouse gas emissions.
Waste heat recovery methods used with industrial process heating
operations intercept the waste gases before they leave the process,
extract some of the heat they contain, and recycle that heat back to the
process.
Common
methods of recovering heat include direct heat recovery to the process,
recuperators/regenerators, and waste heat boilers. Unfortunately, the
economic benefits of waste heat recovery do not justify the cost of these
systems in every application. For example, heat recovery from lower
temperature waste streams (e.g., hot water or low-temperature flue gas) is
thermodynamically limited. Equipment fouling, occurring during the
handling of “dirty” waste streams, is another barrier to more
widespread use of heat recovery systems. Innovative, affordable waste heat
recovery methods that are ultra-efficient, are applicable to
low-temperature streams, or are suitable for use with corrosive or
“dirty” wastes could expand the number of viable applications of waste
heat recovery, as well as improve the performance of existing
applications.
Various Methods for Recovery of Waste Heat
Low-Temperature
Waste Heat Recovery Methods – A large amount of energy in the form of
medium- to low-temperature gases or low-temperature liquids (less than
about 250 degrees F) is released from process heating equipment, and much
of this energy is wasted.
Conversion of Low Temperature Exhaust Waste Heat – making efficient use
of the low temperature waste heat generated by prime movers such as
micro-turbines, IC engines, fuel cells and other electricity producing
technologies. The energy content of the waste heat must be high enough to
be able to operate equipment found in cogeneration and trigeneration power
and energy systems such as absorption chillers, refrigeration
applications, heat amplifiers, dehumidifiers, heat pumps for hot water,
turbine inlet air cooling and other similar devices.
Conversion of Low Temperature Waste Heat into Power –The steam-Rankine
cycle is the principle method used for producing electric power from high
temperature fluid streams. For the conversion of low temperature heat into
power, the steam-Rankine cycle may be a possibility, along with other
known power cycles, such as the organic-Rankine cycle.
Small to Medium Air-Cooled Commercial Chillers – All existing commercial
chillers, whether using waste heat, steam or natural gas, are water-cooled
(i.e., they must be connected to cooling towers which evaporate water into
the atmosphere to aid in cooling). This requirement generally limits the
market to large commercial-sized units (150 tons or larger), because of
the maintenance requirements for the cooling towers. Additionally, such
units consume water for cooling, limiting their application in arid
regions of the U.S. No suitable small-to-medium size (15 tons to 200 tons)
air-cooled absorption chillers are commercially available for these U.S.
climates. A small number of prototype air-cooled absorption chillers have
been developed in Japan, but they use “hardware” technology that is
not suited to the hotter temperatures experienced in most locations in the
United States. Although developed to work with natural gas firing, these
prototype air-cooled absorption chillers would also be suited to use waste
heat as the fuel.
Recovery of Waste Heat in Cogeneration and Trigeneration
Power Plants
In
most cogeneration and trigeneration power and energy systems, the exhaust
gas from the electric generation equipment is ducted to a heat exchanger
to recover the thermal energy in the gas. These heat exchangers are
air-to-water heat exchangers, where the exhaust gas flows over some form
of tube and fin heat exchange surface and the heat from the exhaust gas is
transferred to make hot water or steam. The hot water or steam is then
used to provide hot water or steam heating and/or to operate thermally
activated equipment, such as an absorption
chiller for cooling or a desiccant dehumidifer for dehumidification.
Many
of the waste heat recovery technologies used in building co/trigeneration
systems require hot water, some at moderate pressures of 15 to 150 psig.
In the cases where additional steam or pressurized hot water is needed, it
may be necessary to provide supplemental heat to the exhaust gas with a
duct burner.
In
some applications air-to-air heat exchangers can be used. In other
instances, if the emissions from the generation equipment are low enough,
such as is with many of the microturbine technologies, the hot exhaust
gases can be mixed with make-up air and vented directly into the heating
system for building heating.
In
the majority of installations, a flapper damper or "diverter" is
employed to vary flow across the heat transfer surfaces of the heat
exchanger to maintain a specific design temperature of the hot water or
steam generation rate.
Typical
Waste Heat Recovery Installation

In
some co/trigeneration designs, the exhaust gases can be used to activate a
thermal wheel or a desiccant dehumidifier. Thermal wheels use the
exhaust gas to heat a wheel with a medium that absorbs the heat and then
transfers the heat when the wheel is rotated into the incoming airflow.
A
professional engineer should be involved in designing and sizing of the
waste heat recovery section. For a proper and economical operation, the
design of the heat recovery section involves consideration of many related
factors, such as the thermal capacity of the exhaust gases, the exhaust
flow rate, the sizing and type of heat exchanger, and the desired
parameters over a various range of operating conditions of the
co/trigeneration system — all of which need to be considered for proper
and economical operation.
