DROP TEST NEUTRALIZING AMINE EQUIVALENCE (PPM)
CHA (4); DEAE/DEEA (5); MOPA (3.8); MEA (2.5); MOR (3.8); TEA (6)

ALKALINITY TITRATION COMPONENTS: 1 x 5072 Instruction 1 x 9198 Sample Tube, Graduated, 25 mL, plastic w/cap 1 x R-0645 Total Alkalinity Indicator, DB 1 x R-0869 Neutralizing Amine Titrating Solution, DB.

IMPORTANT: This is an alkalinity test designed for use on pristine steam condensate, where the only alkalinity present comes from the neutralizing amine treatment itself. If carbonates or other alkaline materials enter into the condensate from boiler carryover or leaks in a condenser or heat exchanger, these substances will also be titrated as alkalinity, resulting in a false amine reading. Nor can the test be used to detect the presence of neutralizing amines outside a condensate system. However, if the test suddenly reads higher than normal levels of neutralizing amine, or if there is a significant reading when the operator knows no amine has been added to the system, it is evidence of either boiler carryover or a cooling water leak introducing contaminants into the condensate.

PROCEDURE:

1. Rinse and fill 25 mL sample tube (#9198) to 25 mL mark with water to be tested.
2. Add 5 drops R-0645 Total Alkalinity Indicator. Swirl to mix. Sample should turn green.
3. Add R-0869 Neutralizing Amine Titrating Solution dropwise, swirling and counting after each drop, until color changes from green to red. Always hold bottle in vertical position.
4. Subtract 2 from the number of drops of R-0869 Neutralizing Amine Titrating Solution used and multiply the result by appropriate factor (see CONVERSION FACTORS). Record as parts per million (ppm) neutralizing amine.

CONVERSION FACTORS:

To express neutralizing amine as: Multiply result from Step 4 by:

Cyclohexylamine (CHA)..............4
Diethylaminoethanol (DEAE)/ Diethylethanolamine (DEEA).........5
Methoxypropylamine (MOPA)........3.8
Monoethanolamine (MEA)...........2.5
Morpholine (MOR).................3.8
Triethanolamine (TEA)..............6
