Air quality management

There are several different strategies for air pollution control. The strategy just discussed and shown in Fig. 5-1 is called the air quality management strategy. It is distinguished from other strategies by its primary reliance on the development and promulgation of ambient air quality standards. 

For the air quality manager to place model estimates in the proper perspective to aid in making decisions, it is becoming increasingly important to place error bounds about model estimates. In order to do this effectively, a history of model performance under circumstances similar to those of common model use must be established for the various models. It is anticipated that performance standards will eventually be set for models.

The environmental impact of SOj emissions has gained much attention over the past ten years. The United States Environmental Protection Agency (EPA) New Source Performance Standards (NSPS) went into effect in 1989. The ruling covers new, modified, and reconstructed FCC units since January 1994. It should be noted that the Southern California Air Quality Management District (SCAQMD) board has established a limit of 60 kilograms of SO per 1,000 barrels of feed for the existing FCC units.

We have seen the wide variety of methods now available to calculate air quality. The priority for adapting these methods to current needs is dearly established. Only through clear expositions of model performance and simple implementation procedures will the present techniques have a favorable impact on air quality management. A growing appreciation by the specialist community of the policy requirements will be essential for the successfid fiilfUlment of these goals.

Increasingly strict environmental control laws have resulted in a need to reduce the SOx emissions from most stationary sources, including FCCU s. The United States Environmental Protection Agency has proposed that limits be placed on the amount of SOx emissions from new, modified and rebuilt FCCU s ( ). Several local agencies have already placed limits on SOx emissions. For example, the California South Coast Air Quality Management District, in which 10 refineries are located, has an SOx emissions limit of 60 kg (132 lbs) of SOx (expressed as S0 ) per 1,000 barrels of oil fed to the FCCU. ... 

In order to meet the California South Coast Air Quality Management District SOx emissions limit, the 50,000-barrels-per-day unit, referred to above, would have to reduce its SOx emissions from 23.3 tons a day to 3.3 tons a day, a reduction of 86%. 

The prototype HD CatOx system was permitted by the California South Coast Air Quality Management District (AQMD) in 1990, and operating results met the conditions of the AQMD s permit to operate. 

This technology is currently commercially available. SR2 has permits to operate LTTD plants in 11 states Arizona, Arkansas, California, Georgia, Idaho, Nevada, New Mexico, Oregon, Texas, Utah, and Washington. Permits to treat chlorinated hydrocarbons have been issued by Arizona and the South Coast Air Quality Management District (SCAQMD) in California. 

In urban areas, the concentrations can of course be much greater. For example, in Paris in late September 1997, NOz concentrations exceeded 210 ppb (Environmental Science Technology, 1997). In metropolitan Toronto, Canada, peak 30-min average concentrations of 40 ppb have been reported (Schiff et al., 1986). In the Los Angeles area, maximum 1-h concentrations of about 200 ppb are encountered (Air Quality Management District summary data see Appendix IV).
