Heat exchangers decontaminated of heavy organic polymeric sludge to restore operational performance
33% reduction of allocated outage time
Saved hundreds of thousands of dollars in mechanical cleaning costs and associated outage time
FQE Solvent-PR is used for dissolution of many polymers common to the petroleum refining and petrochemical industries
During operation, the degradation of sulfolane produced a foulant consisting of heavy organic material and polymer.
Due to conditions at the plant the project needed to be completed within a short timeframe. To avoid any major economic setbacks, the refinery had to meet the following stringent conditions:
Since other competitive products could not meet these criteria, FQE Chemicals was tasked with developing a new solvent product. The result was the development of FQE Solvent PR+. During the application, it was dispersed in a hydrocarbon cutter stock and heated to a temperature of 160-180°F (70-82°C). The material was circulated through the sulfolane unit until all the heavy organics and polymeric materials were fluidized. The project was deemed completed in 4 hours, thereby providing a 33 percent reduction of the allotted timeframe.
