Test results clearly demonstrate the effectiveness of MAXSCAV. Treatment at 190 0 C (374 0 F) for 15 minutes and 177 0 C (350 0 F) for 48 hours, both before and after PPA addition. Think of these experiments as two sequential tests. The blank generated 26,000 ppm H 2 S after 48 hours. When we added acid and heated for an addition 48 hours, 3,500 ppm of additional H 2 S was generated.
