- Application Information
- The performance of Versa-TL® 4 was demonstrated in a 250 psi industrial boiler with a history of extreme sludge problems.
- The plant had four boilers each rated at 35,000 lbs. per hour, steam generation.
- The feedwater was composed of softened water and return condensate.
- The quality of the feedwater was controlled, but occasionally changed rapidly, when the demand for water in the plant was high.
- When this surging occurred, the capacity of the zeolite softener system was exceeded.
- The hardness is the feedwater increased to as high as 100 ppm (80 ppm calcium and 19 ppm magnesium) contributing to the sludging problems.
- The sludge was soft and sticky. All feed water was deaerated to 20-40 ppb of oxygen.
- Chemical treatment included sodium hydroxide, sulfite and phosphate.
- Conductivity was monitored and maintained below 2600.
- Blowdown throughout the operating period was maintained at 10-12%.
- Treatment of the water using sodium lignosulfonate showed no promise.
- Addition of sodium carboxymethyl cellulose (CMC) or sodium acrylate at 2-5 ppm showed some tendency to reduce the scale but the heavy sludge remained a problem.
- From the elemental analysis of the sludge, it appeared to be composed of silicate, iron oxide, hydroxyapatite and magnesium hydroxide as the predominant components and a low concentration of copper oxide.
- Since none of the common additives were effective it was decided to try the Versa-TL® 4.
- One of the boilers was treated with 3 ppm of Versa-TL® 4 while a second boiler was maintained on 5 ppm of sodium acrylate. All conditions remained comparable.
- Immediately after the start of the feed of the Versa-TL® 4, the suspended solids visibly increased in the boiler water.
- After two months of operation, both boilers were shut down and were opened for inspection.
- The examination revealed that the boiler treated with sodium acrylate had shown no improvement and had about 1/16 of an inch of soft sticky sludge throughout the boiler.
- On the other hand, the Versa-TL® 4 treated system not only kept the boiler sludge free, but re-dispersed the old sludge that was in the system when the treatment was initiated.
- The generating tube ends, the steam and mud drum walls were free of sludge.
- Iron control in systems up to 1,000 psi. Ultra high temperature stable deflocculatns for contaminated and high density salt muds.
- Excellent dispersant for stressed conditions, anti-staic agent.
