My question is,
Is there is any importance of reactor inlet temperature while calculating LHSV ? As in LHSV formula/equation there is no any temperature term. Simply we calculated LHSV as,

LHSV = volume of charge per hour / volume of catalyst

As during operation, the reactor inlet temperature is fixed lets…Read more

Hope so you all are fine

I am confused in calculating average molecular weight of heavy Naphtha Feed that comes from NHT Unit and flow towards reforming unit.

As the formula for average molecular weight of gases is

M.W(avg) = sum of (mole fraction of components x molecular weight of components)

So let suppose I calculated the…Read more

My question is

How much time is needed to regenerate the catalyst in CCR process. Let suppose if it took 10 min or 20 min then there will be stopagge of production for 20 min ?

Kindly guide me in detail

Thanks
