摘要

本研究之「修正相關係數法」指的是以美國環保署發展的「相關係數法」，分兩部份來估算石化工廠揮發性有機物（Volatile Organic Compounds，簡稱VOCs）排放量，第一部份是針對沒有進行「洩漏偵測及維修計畫(Leak Detection and Repair/LDAR)」的設備元件，本研究則以排放因子來計算其排放量，第二部份是針對有進行LDAR檢測的設備元件，本研究則以美國環保署發展的「相關係數法」來計算其排放量，最後，再將兩部份之排放量加總即為該廠之揮發性有機物之設備元件總排放量。
上述「修正相關係數法」有以下優點：(l)所有LDAR的檢測值均對總排放量直接產生影響，及(2)不需要對全廠設備元件檢測，即可估算其總排放量。

In this study, the modified correlation approaches are derived from the correlation approach of US EPA. The modified correlation approaches compute the volatile organic compounds (VOCs) emission rate of the process equipments based on the results of two parts. The first part is the values computed from the emission factors of the process equipments without the Leak Detection and Repair (LDAR) technique. The second part is the values computed from the correlation equations of the process equipments with the LDAR technique.
The advantages of the modified correlation approaches are (1) the total emission rate is computed straightford by the all detection results of the real process and (2) it is not necessary to compute the total emission rate of the VOCs by the all process equipments.
