Description:
The report gives results of an examination of fugitive emission data from Synthetic Organic Chemical Manufacturing Industry (SOCMI) processing units (Collected under earlier EPA studies) for correlations between process variables and leak frequency. Although line temperature did not have a consistent relationship with leak frequency, the data showed that leak frequency increased with increasing line pressure. Also, emission factors for three process types (vinyl acetate, cumene, and ethylene) were developed and presented. Increases in mass emissions due to occurrence and recurrence of leaks for these three process types are also estimated. Finally, the effect of adjusting portable hydrocarbon readings by chemical response factor curves on leakage frequency estimates is investigated. Despite the wide range of response factors encountered, the adjusted leak frequencies were essentially the same as the unadjusted frequencies.
