Box 37 Westlake, LA 70669 Attentioni Mr. Reynolds We have analysis of the VCM waste from the CONOCO plant at Westlake, LA. Element Sodium Potassium Lead Vanadium Sulfur Concentration 13 ppm Nil 3 ppm 3 ppm Nil We have previously recommended K0NT0L KI-66 for this case because of the high sodium content (relative to vanadium and lead). We can make a current recommendation, with some restrictions. For this particular fuel, proper treatment is 0.04 gallon/ 1000 gallons of VCM waste, or less than a half-pint for 1000 gallons of waste. However, we understand that the contaminant (sodium) level changes a great deal from batch to batch. The ideal method is to draw a representative sample of material from each waste load, analyse for sod ium, and adjust the injection rate according to the formula given on the KI-66 data sheet. A simple graph can be drawn up showing dosage or pumpstroke vs. sodium level. For example, if sodium level varies from 100 ppm to 1000 ppm, the KI-66 dosage rate will vary from 0.18 gallon to 1.8 gallon for every 1000 gallons of VCM waste.

Analysis and dosage adjustment must occur before the fuel is burned, or such attempts at matching dose rate to contaminant level will be useless. If CONOCO can provide rapid analysis and pump adjustment, this method will work well and most economically. If rapid analysis is not possible, the dosage rate could be set for the worst possible contaminant leveli for example, 1.8 gallons KI-66 for each 1000 gallons of VCM waste (corresponding to 1000 ppm Na), This will suit until a contaminant history can be established and a dosage rate, mathematically weighted to treat most cases, can be determined. Overtreatment will cause no problem, other than using a little more additive than necessary* undertreatment could result in deposits and corrosion of refractory. We recommend a trial be run for 2-4 weeks minimum, with combustion unit fireside inspection prior to and following the test period. If possible, the unit should be cleaned in order to better see the results of the trial. Additive Requirements Sodium Level 100 ppm (0.18 gallon KI-66/1000 gallon waste) additive cost $2,35 Sodium Level lOOOppm (1,8 gallon KI-66/1000 gallon waste) additive cost $23.50 KONTOL KI-66 is priced at $13.06/gallon delivered to your plant, Injection Pump Tretolite will provide the required injection pump. Injection of KI-66 should be as far upstream of the combustion chamber as possible. This will ensure good mixing of the additive with the waste stream. We welcome your comments, as well as the opportunity to be t of service to CONOCO VCM ^r
