The SWAP is not a carbon capture process
but a laboratory-verified carbon conversion and elimination process. The
SWAP has been independently verified by standard analytical instruments
to convert CO2 in the presence of
H2S over a catalyst that is abundant
and inexpensive. The SWAP creates incentives for the carbon-emitting
industries to rapidly institute on-site CO2 capture
programs. Widespread implementation of the SWAP can develop additional
profitable markets for CO2, while
also improving the processing economics of sour gas and high-sulfur
crudes.
Laboratory studies show the SWAP drives
a sulfur cycle which enables the customer to generate H2S
from most hydrocarbon wastes. Landfills in particular may benefit from
this process as they emit methane. These sites can also become a source
of raw materials. The SWAP, which converts CO2 by
rearranging its atomic components, may be used to create new carbon-sulfur
molecules called Carsuls, which may find application as carbon fiber-like
materials in construction, aerospace, manufacturing and electronics.
Unrefined sour natural gas is fed into
a catalytic reactor where the SWAP reaction occurs, and CO2 and
H2S are converted into water, sulfur and
carbon. The SWAP has been laboratory verified to reduce H2S
to below 4ppb and convert 99.98 percent of the CO2.
The SWAP may be ideal for remote sour gas fields, capped because of high
production costs for H2S disposal and
gas transport. The SWAP may also be of value to sour gas processing units
that have routine difficulty reducing H2S
tailgas emissions from Claus reactors and its variants.
The SWAP-driven Sulfur Cycle allows for
related reactions that can produce hydrogen from hydrogen sulfide. For
refiners this may be a cost-effective solution to recover some hydrogen
while it may find other applications for fuel cells.
