Cost of
catalyst decay.
v
Poor catalyst performance and
unexpected catalyst decay could be caused by:
unsuitable catalyst selection, poor catalyst quality,
poor process optimization, poor feedstock quality, serious catalyst
maltreatment.
v
The consequences of poor catalyst performance are expensive:
inefficient raw material usage, increased effluent,
increased energy costs, reduced plant capacity, poor product quality.
v
If performance monitoring is ineffective then catalyst
decay might not be evident early in
catalyst
life but become evident suddenly late in catalyst life.
Catalyst performance monitoring needs to be
well-planned to be effective.
v
An early plant shut-down for an
unplanned catalyst change will often be expensive:
lost
production, replacement catalyst cost, catalyst change-out charges.
v
Well-informed
catalyst selection is obviously essential but catalyst life-tests take a long
time.
Accelerated decay tests
are often used but poorly-designed accelerated tests may be invalid.
v
Does your catalyst
evaluation programme indicate which catalyst will be most cost-effective
during its lifetime use in the plant?
