The following table is used to classify all raw materials and air pollutants into the appropriate category or sub-category. In some cases, a material may appear in more than one category. For example, heavy organics with vapor pressures less than 1 mmHg cold be detected (depending on temperature) by NJ Air Test Method 3 as a hydrocarbon and/or by Method 1as a liquid particulate. The material would be placed in the Total VOC category (sub-category: OTHER VOC) as well as in category Total Particulate (sub-category: LOC). Also, an acid may appear in both the Total Particulate category as well as the Acid Gases category depending on whether or the acid combines with water to form liquid particulate. If it is known that a material would not fall into any other categories and sub-categories double-listing is not required. However, double listing is recommended when there is uncertainty as to how the material will behave during a stack test. SuperPro Designer allows you to double-list materials into more than one categories.
|
|
SuperPro Designer allows you to define up to five more categories (user-defined pollutant categories) in case your state regulations require you to do so. You can define these extra categories (along with their regulated limits) in the Emission Limits Dialog that appears when you select Preferences } Emission Limits from the flowsheet’ s context menu. |

1. All air pollutants and raw materials are characterized using these standardized categories. Materials which are not accurately described by the above categories and sub-categories may either be listed individually or be included under one of additional five user-defined categories that SuperPro Designer allows you to introduce (for more information on how to do that , see Emission Limits Dialog dialog). This listing excludes distillates of air as defined in NJAC 7:27-8.1. The addition of categories and sub-categories after approval may require an alteration to the permit and certificate for the process.
2. This sub-category includes infectious agents requiring practices, safety equipment and facilities that constitute Biosafety Level 2 or higher. See HHS Publication No. (NIH 88-8395, 2nd Edition (May 1988)).

Notes: For all listings above which contain the word “compounds” and for glycol ethers, the following applies: Unless otherwise specified, these listings are defined as including any unique chemical substance that contains the names chemical (i.e. antimony, arsenic, etc.) as part of that chemicals infrastructure.
a) X’CN where X-H’ or any other group where a formal dissociation may occur. For example, KCN or Ca (CN)2
b) Includes mono- and di- ethers or ethylene glycol, diethylene glycol, and triethylene glycol R-(OCH2CH2)n-OR’ where:
n = 1,2 or 3
