Not the most efficient, but definitely the cleanest
cost
effective system for waste treatment.
Enables simple incineration (and preferably
gasification)
of any waste such as manure, plastic, tires etc. for
creating steam and
using it for power or for desalination.
Stage 1: Chillers
powered by the waste heat lower a
coolant's temperature.
Stage 2: Air conditioning lowers the coolant's
temperature further, while sending heat to the water
which will later become steam .
Stage 3: The exhaust (smoke) from the incineration is
passed in pipes through a counter-current water pre-
heater, heating the water to be turned to steam
further, and cooling the exhaust.
Stage 4: The exhaust is passed through a heat
exchanger
passing much of its heat to the coolant, lowering the
exhaust's energy, volume and pressure considerably.
Stage 5: The cold exhaust, is passed through a filter,
loosing all heavy particles.
Stage 6: The remaining mostly clean exhaust is now
passed through a large vegetation tower, cleaning it
from CO2 and creating oxygen.
Stage 7: The gas, now mostly oxygen, is fed back into
the process. Excess oxygen is released to the
atmosphere.
The output of the process is steam. The input is used
tires, manure, plastic or any other waste.
The initial cost of such a system shouldn't be too
much,
everything is standard equipment and making a tall
tower with vines growing in them shouldn't cost much
either.

I like stage 6. After processing some tons of CO2 you will have heavy trees out there; and you need to do something with them. You could bury them to get oil some mileniums ahead. We could do this anyway (plant trees, let grow up, and bury them ) for clean up the atmosphere and prevent global warming.
// The output of the process is steam.//
And a lot of trees :-) |

Algae systems for power plants are widely researched, but to date have not been economically viable. As the technology improves that may change, but it is not there yet. |

This sounds like a lot of existing approaches, described in a not very believable way. |

No. The filtering of smoke is usually done with the
least amount of energy, ie - passing through water
and filter. My approach is to spend a percentage of
the energy on cleaning the smoke, basically by
cooling it. There would be no chimney for this plant. |

[meche] I know. There's a claim that ... wait looked
it up, its not a claim its official, that Israeli Electric
Co developed an algae system with Symbiotic Ltd.
for lowering emissions. It works at the Tel Aviv
Rothenberg power plant. But I did not talk about
algae. I'm talking about a large orchard or a
vegetation tower. |

Are you sure? The tower may have to be ... rather large. |

Algae is, by far, the most efficient possible carbon sink for this sort of operation. I'm aware of several different operations attempting this, and several that have in the past (and gone bankrupt). Anything else is going to have a much higher energy and infrastructure demand. |
