[Gasification] Marine Wastes

[Gerald Kutney]

There have been lots of useful suggestions.  Most often plasma-related
technologies have been recommended.  What are the advantages of plasma over
other gasification methods for treating MSW and related wastes, such as
marine?

plasma gasification has many routes. graphite electrodes plasma and plasma
torch. plasma torch again have air plasma torch and steam plasma torch. we
have commissioned air plasma torch based system in India in 2010 and it is
running successfully. operating to despose 3000kg per hour industrial
hazardous waste. plasma gasification is best process to avoid any pollution
as it burn substance at more than 1400 deg centigrade to break any compound
in primary elements and so avoid formation of furan etc gases.

it is very well viable and we can provide even skid mounted system also.

I know many system failed due to wrong design but in japan such system is
working since 2006 for MSW also and generating electricity.

The DoD has tried to use plasma gasification for MSW and it was a miserable
failure, costing huge input power, high operating expenses including
replacing carbon electrodes as expensive and frequent, inconsistent
performance, never achieving the rated output and very unstable operation.
The multi-million dollar system was scrapped. Others have also made it to
the scrap yard. 

 

We have a small gasification system that can operate on marine waste,
MSW/RDF, a system for presorting the MSW into a RDF as a single unit, and
operate an IC engine as an independent unit and or supply thermal power. It
is 18 ft. x 8 ft and around 8 ft. tall and operates on around 200
pounds/hour and when mixed with other materials, can also operate on waste
oils such as those that might be derived from bilge water. It produces a
white/grey ash with some clinker in it, with very low carbon content and
volumetric reduction of 90%+. 

 

To those who are considering developing this type of system, any existing
process used in gasification should be discarded to avoid wasting a huge
amount of time and resources without success. This comes after many decades
of seeking innovative methods to address the problems. The list of what
doesn't work is quite extensive.

plasma gasification is only best solution and i have experience as project
incharge of such plant to despose of the industrial hazardous waste and
generate power.

we can provide you consultancy  for this project

Is anyone aware of the use of gasification (or pyrolysis) to treat solid
marine wastes from ships and vessels; either at the vessels or at the ports.
If not, I plan to look at treating MSW as a proxy.  Any comments or ideas?
