Bsudhakar, I could not agree more.

+ Down gauging the AF pump is important to really know your dosage.
+ Measuring Si in Naphtha and LCGO is important. >20 ppm could cause downstream catalyst issues.
+ Consider injecting only carrier early in the foam observation, then switch to carrier+AF later in the cycle
+ Use continuous level (if you have them) to optimize dosage timing.
