I use the following criteria:
- when steell is not of series 300, max TAN 0.3/0.5 the first in case no protective additive addition;
- in case of steell series 300, accepted TAN up to 1.5;
- in some case this formula is also used for assessment: S>2*TAN.

Making reference to semirigen reforming, as follows has to be monitored:
- DWAIT, delta beeing expected weight average reactors inlet temperature vs actual. Parameters ( RON, Naphthenes, aromatics, LHSV) have to be normalized, catalyst suppliers provide General operating manual where...
Dear all,
I recently experimented silica contamination of semirigen platforming catalyst. Silica comes from antifoaming agents used upstream. I'd like information relevant to criteria followed for monitoring pick up and breakthrough, if any, from upstream hydrotreating unit.
