Modular Biomass Gasification - Simple & Cost-Effective
Gasification is a thermochemical process unlike an incineration or combustion
process. Gasification is a conversion process intended to produce more valuable and useful products from carbon containing
materials. Gasification processes operate with limited amounts of oxygen, while combustion processes operate with excess oxygen.
Combustion or incineration thermally destroys carbon into heat, while gasification converts carbon into valuable ecologically-friendly
intermediate products. Gasification can use natural gas, coal, oil, biomass, including manures, and just about any carbon
containing material as a feedstock. The heart of the Ankur Scientific
biomass gasification CHP plant is the downdraft gasifier with no internal moving parts. The process by which biomass is converted
into gas uses various thermo-chemical reactions: pyrolysis, oxidation, reduction.
The main output is a clean gas composed of hydrogen (H2), methane (CH4), carbon dioxide
(CO2) and carbon monoxide (CO). This fuel gas presents a lower heating value (LHV) of typically 125-175 btu/cf
suitable for use in gas engines. The conversion efficiency of the downdraft gasifier reaches 84-86%.
Cogentech has worked with a team of worldwide experts to produce
the design of a modular biomass gasification CHP system utilizing best-in-class technologies to meet the needs of wood products
companies, rural municipalities, and other biomass sourcing entities looking for low-cost and ecologically-responsible energy
solutions.
The design objective that we met was to identify globally-proven and scalable technologies that
would be 'right-sized' to optimize the use of nominally 10-15 TPD of woody biomass fuel for the production of 500
kW of baseload power generation. The target solution utilizes gasifier modules in 10-15 TPD increments and power generation
modules in corresponding 500 kW packages. For every 10-15 TPD increment of fuel available and 500 kW of electricity
demand, identical modules can be added to the scalable system.
The initial 10-15 TPD / 500 kW package
is strategically sized to serve the needs of various rural communities and commercially-scaled wood products locations. In
developing this cost-effective, pre-engineered, modular system design, Cogentech has transcended the industry status-quo that
seeks larger economy-of-scale while ignoring the real needs of the end user. Our strategic design
consists of Ankur gasification modules + 2G CENERGY's (Germany and Florida, USA) syngas power generation equipment coupled
in 15 TPD / 500 kW increments. By pre-engineering the entire plant, we have arrived at a cost-effective, easy to operate
biomass conversion system with guaranteed performance and cost-saving results. By utilizing various woody waste fuels,
rural communities otherwise subject to the costs and pollution of diesel powered electric plants, can experience not only
signficant utility cost reduction, but at the same time can also keep fuel purchase dollars in their local economy ... another
WIN-WIN solution from COGENTECH.
