As discussed in the Existing Commercial Projects portion of this section, several commercial projects use the Texaco coal gasification process. However, these plants are for chemical synthesis gas application and do not include IGCC power generation. In addition, most commercial Texaco projects do not use syngas coolers to generate steam from the hot raw coal gas. 

Plant locations can also create extremes in permitted air emissions. For example, the Cool Water IGCC power generation facility in Southern California had to meet emission levels significantly lower than those which new coal-based power plants have to meet under the NSPS (6). Issues such as best available control technology, prevention of significant deterioration, and nonattainment area tend to drive permitted air emissions to extremely low levels. In addition, various provisions of the Clean Air Act Amendments of 1990 favor new power plants to have lower air emissions than specified by the NSPS. These are discussed in more detail at the end of this section. 

Distinguishing Characteristics. The key advantage of the Texaco coal gasification technology is the extensive operating experience at full commercial scale. Furthermore, Cool Water is an IGCC power generation facility, operated by conventional electric utility staff and is one of the cleanest coal-fired power plants in the world. 

EPRI Studies. In 1987, EPRI contracted with Fluor Daniel and Destec to conduct a detailed technical and economic analysis of IGCC power generation based on 400-MW plants for both Texas lignite and Wyoming subbituminous coal (9). Central and South West Services, Houston Lighting and Power, Texas Utilities Electric Company, and the Salt River Project also participated in this analysis. 

These four diagram types provide information for the main gas components and performance parameters as a function of O2, H2O, and fuel consumption at a glance. Because the information needed has now been defined, more complex calculations can be carried out for the two coals shown in Table 5.10 at 30 bar. This pressure is selected because of the suitability for various chemical syntheses [10] and integrated gasification combined cycle (IGCC) power generation including CO2 capture as well [11].
