AMSTERDAM, 6 October 2021 – Ergon, Inc., has selected Avantium RDS to evaluate two hydroprocessing catalyst systems, utilizing the Avantium Flowrence® technology.
The results obtained in Avantium Flowrence® unit with 16 parallel single-pellet-string reactors corresponded closely to results obtained at Ergon’s conventional unit with a single-reactor pilot and catalyst volume above 500 cc, with relative average deviations less than 1% for HDS and HDN. In the conventional unit, the catalyst schemes were tested one at a time, while in the Flowrence® unit the schemes were tested in parallel and in quadruplicate for increased accuracy – at two different space velocities – see the PTQ article here.
Due to excellent hydrodynamics of the single-pellet-string reactor and sophisticated process control, the Avantium unit achieved high reproducibility resulting in average deviations of less than 0.2 wppm for HDS and HDN across the quadruple reactors with the same loading scheme.
Avantium high-throughput technology unit is a suitable alternative to the conventional pilot plant for the customer’s lube oil hydrotreater and with clear advantages of parallel testing, lower cost and feed amounts. It also has increased flexibility on testing more options. Moreover, due to the small scale of testing, safe operation can be accomplished in a laboratory setting where this would be difficult to achieve with the same number of reactors at conventional scale.
While this particular study considered base oil hydrotreating for a single feedstock, Avantium equipment and methodology can also be employed to evaluate several feedstocks simultaneously. Moreover, the same technology has been used successfully to examine other fixed-bed catalytic processes, including hydrocracking, hydrodewaxing, catalytic reforming, and hydroisomerization.
“This study clearly shows the scalability of Avantium high-throughput technology to much larger conventional pilot plants. Equally important is the reproducibility across the quadruple reactors. We are committed to providing our customers meaningful results to enable fact-based decisions and ultimately increase their competitiveness and profitability.” Tiago Vilela, Director Business Development, Refinery Catalyst Testing
