Extra Help for Question 6
Provide information on the contaminants in the waste gas. Include the contaminant name, the contaminant CAS number, the contaminant concentration in the waste gas in percent by weight, the vapor pressure of the contaminant atmospheres, Pascals, bars, pounds per square inch, pounds per square inch gauge, millimeters of mercury, or inches of water, the solubility of the contaminant in the scrubbing liquor, and the overall removal efficiency of the contaminant. To indicate the solubility of the contaminant in the scrubbing liquor, use the following definitions:
Insoluble: The contaminant does not mix with the scrubbing liquor to form a solution. The two liquids exist as separate layers in contact with one another.
Slightly Soluble: Only a small amount of the contaminant mixes with the scrubbing liquor to form a solution. Most of the contaminant exists as a separate layer in contact with the scrubbing liquor.
Highly Soluble: Most of the contaminant mixes with the scrubbing liquor to form a solution. A small amount of the contaminant exists as a separate layer in contact with the scrubbing liquor.
Miscible: The contaminant and the scrubbing liquor complete mix to form a solution.
The Department recognizes that there are no definitive breaks between these definitions. Use your best engineering judgment when indicating the solubility. For additional help, contact the scrubber manufacturer or the Department at (302) 323-3542 or (302) 739-9402.
