Texaco coal gasification
It is a pleasure to be with you today and to be speaking to you about a clean coal technology, the Texaco Coal Gasification Process. Texaco's gasification research began in the 1940s and in the 70s and 80s Texaco incorporated into its goals the production of energy from coal in an environmental clean and technological superior manner. Gasification technology can also be used to gasify other materials such as natural gas, waste refinery gas, oil, petroleum coke, and even organic waste, such as sludge, etc. This technology is also applicable to the manufacture of high purity hydrogen, which we will discuss in a few minutes. Texaco gasification is license in 100 plants throughout the world today. Texaco coal gasification technology begins with grinding the coal and slurrying it with water, pumping the slurry to a gasifier vessel through a burner where it is mixed with oxygen at approximately 2400{degrees} F and pressures of three to six hundred pounds. Here, inside a refractory lines vessel, the partial oxidation of the carbon occurs and produces hydrogen syngas, a mixture of carbon monoxide and hydrogen. The operating temperature (2400{degrees} F) is high enough to melt the mineral matte in the coal, so that it becomes slag and falls to the bottom of the vessel. It is an inert unleachable nonhazardous material. Sulfur within the coal is converted to hydrogen sulfide and is removed by one of several commercially proven technologies as elemental sulfur.
