Hydrocarbon Processing - May 2022 - 65

Catalysts
provide an independent catalyst testing
service. Two available primary approaches
are presently in use: a conventional
pilot-scale system and a high-throughput
system (FIGS. 3A and 3B, respectively).
Each method has its advantages/disadvantages,
as summarized in TABLE 1. Refiners
must select the best independent
catalyst
testing laboratory to suit their
requirements and constraints. While the
authors' experience confirmed that both
approaches provided essential information
for hydrocracking catalyst benchmarking,1,3
many
refiners favor some
laboratories more than others. It is recommended
to proactively contact these
independent laboratories as soon as the
new cycle starts. One laboratory requires
at least 24 mos of pre-booking before the
actual test date. Generally, a typical catalyst
testing campaign could last between
1 mos and 3 mos, but this may vary upon
the number of test scenarios.
From the authors' recent experience,
the testing fee for each catalyst loading
scheme (hydrocracking, one-test scenario)
can range between $40,000 and
$95,000. In general, the service fee for a
hydrotreating catalyst testing campaign is
less expensive than a hydrocracking one,
as it is less complicated. A more important
question is who will pay for the test.
The refiner may pay for the total cost or
ask the catalyst suppliers to share. In general,
the willingness of the catalyst supplier
to share the cost increases with the
value of the catalyst package.
Takeaway. On the surface, independent
catalyst testing seems costly. However, the
service fee is often trivial compared to the
opportunity to distinguish the best catalyst
supplier from an average one. In the
authors' recent experience, a performance
gap for a 54,000-bpd hydrocracker could
be up to $20 MM/yr.
In the June issue of Hydrocarbon Processing,
Part 2 will discuss critical aspects
of a hydroprocessing catalyst testing
program and present best practices/suggestions
to ensure a successful catalyst
benchmarking campaign.
