Global (PINKSHEETS: GTGP) announces the results of the live run at
the cement plant incorporating the MBS technology for Mercury
capture in the cement plant emission gasses. This final report is
the result of the compilation of multiple data sets which were
received over a two month period by MSE and a final analysis
completed by MSE Technology Applications, Inc.
This run was conducted under various conditions which included
different temperatures within the baghouse as well as percentages
of run time and the percentages of MBS added to the stream. It
showed the optimum conditions for the mercury capture from the
gasses which exceed the 98% requirement for mercury capture by the
EPA.
This final verified report that we have been looking forward to
since the run took place now enables Global to move forward both in
the United States and abroad for use both in cement plants as well
as power plants.

MBS Full-Scale Test Run Data Analysis
Background Molecular Bonding System
testing was performed at the MSE Technology Applications, Inc.
(MSE) test facility earlier in 2012. That testing proved that MBS
when combined with powdered activated carbon (PAC) or used
independently removed considerably more mercury from a gas stream
than when PAC was used alone. The testing also proved that MBS did
not generate any acid gasses, NOx or SOx. Because of this test
information, a full-scale test that combined MBS with PAC was
performed at a cement plant in August 2012.
Full-Scale Testing
The data generated from the full-scale test of MBS in the cement
plant baghouse has been analyzed to better understand the processes
that occurred during that test sequence. The approximate quantities
of MBS and PAC that were present in the carbon baghouse during the
test sequence are presented in Table 1.

The raw test data is also presented graphically in Figure 1 to
show the correlation between raw mill downtime and mercury removal.
When the raw mill is shut down for maintenance or other reasons,
the amount of mercury going into the carbon bughouse increases and
so does the gas temperature. As can be seen from the data presented
the removal of mercury ranged from a low value of 93.25 to a high
value of 98.69 percent. Notice the last two data points for mercury
removal and raw mill runtime when the amount of MBS was at ~ 16.85
percent of the total volume in the carbon baghouse. Even though the
raw mill was down for substantial amounts of time, the mercury
removal remained at approximately 97 percent. These mercury removal
numbers are higher than on August 15th and 20th when the raw mill
runtime was 67.55 and 62.24 percent and mercury removal was at
95.08 and 93.25 percent, respectively.
The chemical processes that occur within the off-gas system at
the facility are not specifically known, but we can assume the
following -- The mercury contained in the off-gas is present as
several species that include elemental mercury, ionized mercury,
and halogenated mercury. Upon reaching the carbon baghouse, these
species are sorbed onto the carbon or chemically react with
MBS.
Mercury compounds, including those sorbed to carbon, all exhibit
certain amounts of volatilization, which increases with increasing
temperature. When the raw mill is running, the average temperatures
in the carbon baghouse range from 220 to 225 degrees F and increase
to between 255 and 260 degrees F when the raw mill is down. The
quantity of mercury entering the carbon baghouse also increases at
these times due to a number of factors including the increase in
mercury volatility with increasing temperature throughout the
system. The quantity of mercury escaping from the carbon baghouse
also increases during these times because of the volatilization of
mercury previously sorbed to the carbon.
Different forms of mercury exhibit different volatilities with
change in temperature. Of the probable mercury compounds that
should exist at in the baghouse, elemental mercury is the least
stable and strongly volatilizes from carbon at 190 degrees F.
Mercury sulfide, the compound formed by reactions of MBS with
mercury species, does not volatilize appreciably until a
temperature of 350 degrees F is reached. As such, mercury sulfide's
volatilization temperature is well above the temperatures reached
in the carbon baghouse, indicating that mercury would not
volatilize from mercury sulfide compounds at temperatures
encountered during raw mill down time. Therefore, it would be
beneficial to increase the quantity of mercury sulfide that is
formed within the carbon baghouse. Since the quantity of mercury
entering the carbon baghouse is fixed by processes external to that
baghouse, increasing the quantity of fresh MBS and the percentage
of sulfide reagent within the MBS would increase the quantity of
mercury sulfide formed on the surface of the bags and decrease the
amount of mercury released from the baghouse at higher
temperatures.
Conclusions MBS can remove very
significant quantities of mercury from the cement plant off-gas
within the carbon baghouse and not release that mercury during
those periods when the raw mill is not operating. If MBS was added
at higher doses than what was added during the full-scale run, the
mercury removal from the off-gas should be higher than the values
realized during the full-scale test.
