We are looking at alternative option(s) that could expedite the unloading of residue desulfurization unit catalyst (from reactors) other than typical vacuum-out/jack hammering approach.
We have heard about the CO2 explosive technique - and just wondering if anyone has any success stories with that?
Any other feasible approach to be explored?

Vial Romain, Eurecat, r.vial@eurecat.fr
Eurecat has developed CarboDump technology to address catalyst agglomeration issues during unloading: principle is based on the rapid expansion of gaseous CO2 into catalyst bed.
The expansion removes the weak links due to dust, coke, scales or polymers creating the agglomeration of the particles.
In very severe agglomeration situation, CarboDump is used to replace jackhammering inside reactor as an assistance to vacuuming, and therefore increase unloading speed and reduce inert entry exposure.
This option is regularly and successfully handled by Eurecat in client’s site on very severe reactors services like Hydrocrackers, VGO units, specific chemical units…
If you wish so, you can contact us to get more details on the technology as well as a reference list.

Yes we have used Co2 to remove agglomeration of catalyst, coke and sulphur within tanks, vessels and reactors.

We have used CO2 explosives to remove agglomerations of deposits such as catalyst, sulphur and coke.
Often a combination approach is required dictated by accessibility and site constraints.
