In addition to dense loading activities, PETROVAL has developed a new machine to unload reactor, the Catflow®. It is used to unload catalyst through horizontal dump nozzles. The machine creates a fluidized region inside the horizontal dump pipe, and the catalyst is able to flow by applying a delta P over the pipe. The Catflow® increases the safety, the rapidity and the quality.
The Catflow® was developed by PETROVAL's engineers with the objective to unload the catalyst without workers intervening inside the reactor.
Also, the Catflow® reduces the risk of air entry and self-ignition of catalyst. This unloading method permits to achieve a high level of safety on site.
|Catalyst breakage||Between 30% and 50%||Over 50%||Around 20%|
|Installation / Utilisation||Fast but with inert entry in the reactor||Time consuming, heavy equipment required, which is difficult on recessed catwalks||About 130 kg total with a maximum of 35 kg per element, transportable by air freight, installation within 1 hour|
