In a two-phase system of particulate removal from flue gases, a polishing step
embodies a hydroxide ion scrubbing tower with catchment systems for mercury
oxides, sulphuric acid, nitric acid and carbonic acid in relatively small
amounts.
Filtration and fractional distillation will separate these species and will be
recycled, reused or inerted and safely land filled. The second phase follows
with a
full-scale oxidation of the nitrous oxide gas left with carbon dioxide; the
target is
to oxidize with hydroxide ions to capture all the nitrogen in nitric acid
form. Once
this is achieved, the nitric acid is placed in large tanks and subjected to
electrolytic technique. Because the carbon dioxide gas can escape from this
scrubbing, it is separated dried and compressed. The nitric acid tank
comprises a
sealed covering and as the electricity is applied, the anode will produce
oxygen,
the cathode will produce both hydrogen and nitrogen dioxide gas. Each
electrode
is managed so that permeable membranes for hydrogen and oxygen gases are used
downstream from a fume distillation column. The fume distillation columns will
ensure product gas purity, including carbon dioxide gas. The fumes of nitric
acid
are then retained back to the main tanks until the molecules are
electrolytically
treated and the oxygen and hydrogen are captured and reformed into hydroxide
ions, using a gas torch blending system and an electronic charging technique.
Hydroxide production then becomes integral to this process. The carbon dioxide
gas is thus made fully separate from all other compounds and made ready for
dry
thermal reforming in order to harvest and recycle carbon fuel.
