BPP means barrel of feed per pound of catalyst.Sometimes this is given as m3/kg in metric unit. Can anybody show me how the catalyst life is calulated in these units or any of them?
You need to know two things:
1) The total amount of catalyst loaded in Kg
2) The accumulated feed to the plant. for example, if you have been treating 60 m3/h of heavy nafphta for one day, the accumulated feed would be 60m3/h x 24 h= 1440 m3
Then, the "life" of the catalyst is 1440 m3/Amount of cat.
Thanks Nagara. However that is part of the confusion. My daily throughput is about 6m3/hr. Multiplied by 24 will give 144m3/h. Total catalyst loaded in the 2 reactors 3000kg.That gives a catalyst life in decimal points!
Also that will mean the catlayst life is constant.
I will appreciate further elucidation.
