17/07/2017 Q: What is the effect of reducing the system pressure in a gas oil/naphtha hydrotreater? Will this be able to reduce the hydrogen consumption given that there is still allowance on catalyst deactivation? What parameters do we need to consider before reducing the system pressure? (1)
01/06/2013 Q: Our fcc unit works good up to now. In routine checks we find out that the torch oil nozzles are plugged
I would like to ask what can be done (the steam atomizing is ok):
Can we try to inject oil through the atomizing steam side without steam, in case we need it?
Can we try to unplug them using water pressure 50-100bars?

Let me explain further. As you know, the torch oil gun has 2 pipelines (externally for steam and internally for oil). In current operation, the steam flows through the torch oil nozzle (external pipeline) and finally routes to the Regenerator. However, we observe that the oil stream cannot flow, due to plugging of the internal pipeline of the torch oil gun. We want to unplug the oil pipeline, via let’s say water or other oil quality (e.g. light cycle oil). Are they convenient? Other ideas?
