A variety of industries have utilized the technology including chemical production, fertilizer manufacturing, and electrical power generation. Today, the majority of the operating gasification plants worldwide are surface gasification plants designed to produce chemicals, fuels, electricity, and fertilizers.</font></div> <h2><font size="2">Gasification Market</font></h2> <div><font size="2">As of 2008, there were 420 gasifiers at 140 facilities in operation globally, the majority of these being surface gasification plants (source – GTC). World gasification capacity is projected to grow by more than 70% by 2015 with much of the growth occurring in Asia (source – GTC). A number of factors contribute to a growing interest in gasification, including volatile oil and natural gas prices, more stringent environmental regulations, and a growing consensus that CO<sub>2</sub> management should be required in power generation and energy production.</font></div> <h2><font size="2">How does Gasification work?</font></h2> <div><font size="2">Feedstock (for ISCG it is deep coal) is exposed to high temperature and high pressure. In the presence of steam at these conditions a series of chemical reactions occur which convert the feedstock into syngas.</font></div> <div><font size="2">In the case of ISCG, this chemical conversion of the deep coal happens in place in its original seam. The resultant syngas created consists primarily of hydrogen, methane, carbon dioxide, and carbon monoxide.</font></div> <div><font size="2">To create this chemical conversion, two wells are drilled into the deep coal seam. A horizontal injection well is used to introduce oxygen and water into the seam; the oxygen supports a limited and controlled amount of combustion, raising the temperature of the coal and boiling the water to generate steam.</font></div> <div><font size="2">The naturally existing deep underground pressure, along with the elevated coal temperature and the presence of steam, together form the right conditions to gasify the coal. The vertical production well is used to conduct the raw syngas to the surface. Char and ash, which are remnants of the original coal, remain deep underground.</font></div> <div><font size="2">Figure 1. ISCG Well Pair Schematic<br> </font><img class="alignnone size-full wp-image-290" title="img_iscg_diagram" alt="" src="http://swanhills-synfuels.com/wp-content/media/img_iscg_diagram.png" width="380" height="372"></div> <div><font size="2">The coal seam for ISCG development at the Swan Hills Synfuels site is 1400 m beneath the surface, approximately 800 m below the Base of Groundwater Protection (depth limit of fresh groundwater – below this depth, groundwater is saline), eliminating potential for fresh groundwater contamination. Saline water is used for injection into the coal seam through the horizontal well, virtually eliminating the need for fresh water in the ISCG process. </font></div> </font></div> </div> <div style="BACKGROUND-COLOR: #fff; MARGIN: 0px; FONT-FAMILY: Tahoma, Verdana, Arial, Sans-Serif; COLOR: #000; FONT-SIZE: 12px" id="AOLMsgPart_6_7913b0fd-77bd-4e50-bc36-6402fae19eb6"><pre style="FONT-SIZE: 9pt"><tt>_______________________________________________
