GLOBAL TECHNOLOGIES GROUP, INC. RESULTS OF CEMENT PLANT MERCURY EMISSIONS TESTING
April 25, 2012, Sarasota, Florida. Global Technologies Group, Inc. (GTGP.PK) presents report dated April 20, 2012 for Mercury emissions testing completed by MSE Technology Applications, Inc.
Cement Plant Mercury Emissions Testing Using MBS
The United States Environmental Protection Agency (EPA) will implement new mercury emissions regulations in 2013 and many cement plants will not be able to meet the more stringent regulations. Some of these cement plants have installed powdered activated carbon (PAC) systems in an attempt to reduce mercury emissions to comply with the new regulations. However, mercury emissions have not been reduced enough to meet the new regulations at some of the plants.
Global Technologies Group, Inc. (Global) contracted MSE Technology Applications, Inc. (MSE) to perform a series of tests to determine if Molecular Bonding System (MBS), a metals treatment agent, can reduce mercury concentrations within a moist gas stream at elevated temperatures. MBS has historically been used to bond with metals in contaminated soils and has also been previously tested to reduce mercury emissions in a power plant with success.
Four tests were conducted using MBS, PAC and a mixture of MBS and PAC as the treatment agents to reduce mercury concentrations in a flow-through testing apparatus which simulated actual plant conditions. A picture of the test apparatus is shown in Figure 1.
Figure 1. Mercury test apparatus.
The reaction column was packed with denstone, glass wool, and 10 grams of the treatment agent(s) and placed on top of the reaction flask after the system was brought to temperature. The reaction flask contained approximately milliliters 5(mL) of elemental mercury. Nitrogen flow was initiated at 0.5 Liters per minute (L/min) and allowed to flow through the water flask into the mercury flask and up the reaction column through the treatment agent(s). The water flask was heated to 130°F to produce ~ 17% moisture in the system and the mercury flask and reaction column were heated to 250°F to mimic typical cement bag house temperatures.
Test 1 used 100% PAC with a 17% moisture content.
Test 2 used 100% MBS with 17% moisture content.
Test 3 used 90% PAC and 10% MBS with 17% moisture content.
Test 4 used 100% MBS without any moisture in the system.
The tests were all run for the same period of time, using the same gas flow rate, and the same temperatures to produce similar mercury concentrations within the mercury flask and reaction column. After the tests were completed, the reaction column was removed from the mercury flask and the treatment agent(s) were removed, mixed, split into samples and submitted to the MSE Analytical Laboratory for mercury analysis using EPA, SW-846 Method 7471. Table 1 shows the test details and mercury concentration levels for the samples submitted.

Since the cement plant currently uses PAC to reduce mercury emissions,
Test # 1 was designed to be the baseline test and used only PAC in the reaction column. The PAC removed an average of 96 mg/Kg of mercury from the vapor phase in the test system.
Test # 2 used only MBS in the reaction column and the average mercury reduction was 501 mg/Kg, indicating that MBS can remove more than five times the amount of mercury than the PAC
Test # 3 used a combination of 90% PAC and 10% MBS and that combination of materials removed an average of 230 mg/Kg from the vapor phase of the test system. Test # 3 results indicate that the 10% addition of MBS to the PAC can remove more than twice as much mercury than the PAC.
Test # 4 was conducted to determine if MBS could reduce mercury concentrations in a dry environment, which could represent an upset condition at the cement plant. The results for Test # 4 show that MBS in a dry environment removed an average of 398 mg/Kg of mercury from the test system. The average amount of mercury that was removed from each test was plotted and that graph is presented in Figure 2.
Figure 2. Average mercury concentrations.
The testing indicates that MBS removes elemental mercury vapor from a hot nitrogen gas phase. Testing is being conducted to determine if any acid gases, NOX or SOX will be generated using MBS with compressed air in the test system this week.
“The validated Mercury emissions report is part of the data that will be presented to the Portland Cement Association, EPA and other agencies of the government here in the United States and abroad. The results were impressive to both MSE and the cement plant, as the use ofMBS/IFSC2 without the use of PAC can remove more than five times the amount of mercury than the PAC. I believe that now we will be the benchmark for Mercury removal and rid our people of a very dangerous
airbornetoxin not only here but worldwide,” stated James Fallacaro, President.
