Ze-gen
has focused its technology strategy on finding a gasification-derived
solution
that represents the following:
- A high yield of energy output per ton of waste
processed
- A complete solution which doesn’t
require land filling or incineration
- Scalable
and easily replicable
- C&D, MSW-specific with potential for
other similar waste streams
- Combined-cycle
mode
Ze-gen has completed conceptual design of a
product module designed to process
multiple feed stocks such as C&D, MSW, scrap tires and shredded
carpet, and
convert these feedstocks into approximately 30 megawatts of net
electrical output.
This facility can accept 450 TPD of feedstock and up to 100 TPD of
scrap tires.
On a gross basis, this translates into 1.654 MW per ton of waste
processed. Ze-gen
facilities can be expanded in modules, based on availability of
sufficient feedstock
and power purchase contracts. Our facilities are designed to operate 24
hours
per day, 7 days per week with periodic shutdowns for maintenance,
modifications
and upgrades. Our modular and redundant design allows for shutdowns
without interruption
of power generation.
Ze-gen’s proprietary gasification process involves conversion
of organic
and inorganic materials into vitrified slag, molten metal and a
synthesis gas
mixture of carbon monoxide (CO) and hydrogen (H2). The process can be
used for
the conversion of a wide variety of solid wastes such as C&D.
Such a process
will convert a large amount of waste into small volumes of unleachable
slag and
metals, and large volumes of syngas containing a significant BTU
value.
Specifically, syngas is produced from the mix of organic
materials in the feedstock. These materials are introduced into a
molten metal
bed through a feeder. A high temperature reactor contains the molten
bed, which
can be generated whether in the reactor itself or in an external
furnace. Additional
heat is provided from the exothermal reaction of the partial oxidation
of carbon.
Oxygen is injected into the metal. After state-of-the-art treatment of
the gas
to remove impurities, the syngas generated in this process can be used
for power
generation. Ze-gen’s gasification system consists of multiple
feeders,
reactors, and a power supply.
