Flue Gas Capture – CO2 Sequestration
Information on an actual project under discussion follows to illustrate typical target results and methodology
No road transportation of fuel
Slurry water recycled to fines pond, low cost, non-polluting flocculent
Fuel cleansing for efficient burn, longer equipment life
Nitrogen removal (partial) gives high oxidation burn (GGSSI)
Pulse-burn for most efficient high radiant heat to boiler firebox
Benson type once-through boiler
Microbial boiler tube corrosion inhibited
Used, refurbished & guaranteed turbines available to reduce costs
Bubble scrubber for emissions safeguard, no particulate, no bag-house
Point-to-point client power sale possible for 10 mW
Carbon Dioxide capture initiative available (GGSSI)
800,000 tonnes; coal fines in settling pond,
4 kilometres from proposed generating station site,
at an altitude circa 40 metres lower than the site.
No road transportation; can be piped to site,
No washing or major pre-grinding required,
Tested and known component ingredients,
Friability index known,
High Calorific Value;
High Volatile Bituminous
11-12,000 BTU (6-6,500 kcal/kg);**
** = dry basis –main coal body
Some pockets high sulphur;
(By today's & future environmental standards)
40 metre pump head plus 1km piping.
Crush coal to 200 mesh (74 microns) or 0.0029” in water
10 kW/hr per tonne
Micronize to 10-20 microns (fine slurry)
(Sonic cavitational deagglomeration)
(system energy use) = 5 kW/hr per tonne
Float off carbon & hydrocarbons
(system energy use) = 1 kW/hr per tonne
Precipitate contaminants & tramp fractions
Standard Crushers are used with slurried media.
Sonication is the intense electromagnetic
vibration of a massive steel bar.
Reaction Chambers are at each end of
the bar, into which the material to be
processed is fed on a continuous basis.
For high volume industrial
applications such as rock grinding,
environmental remediation and
Beam Mounted Prior to Unit Assembly
(3 magnet -75 kW, 104 Hz unit shown)
The 150 kW (60 Hz) unit uses 5 magnets with
non-sequential firing system.
Sonic micronization of crushed coal slurry is achieved via use of a proprietary high energy sonic oscillator-reactor, which tears the components of the coal apart due to its compression/cavitation de-agglomeration force cycle.
Coal media is torn apart exposing ash and contaminants for separation
A 50 micron particle
Cationic surface adsorbs methane or oil film
Removal of contaminants prior to combustion drastically reduces air emission pollution potential!
Metso Cascade Flocculation System
The resulting fuel is a 70:30 coal/water emulsified slurry finer in particulate sizes than natural Orimulsion.
It is to be injected via a high pressure Olen-Johnson nozzle into an ecoPHASER(oscillating) standing sonic wave @ 440 Hz thermal oxidation unit.
The ecoPHASERoxidizer produces very low Nox.
The level of super-stoichiometry allows for the minimum stack gas flow for given heat releases with minimum CO2 recombination.
Abrasions to boiler minimized
Longer boiler tube life
No energy losses through heating tramp components that do not contribute to energy
Less mass through thermal system for given energy = less volume in gas emissions
Major pollutants removed before firing
No heavy metals or sulphur*to volatilize and combine for emission compliance degradation.
Only combustibles to firing system
Full particulate gasification
Scrubbing costs minimized
