Hi everyone,
We have got Naphtha splitter that splits Naphtha into Light and Heavy Naphtha, whose column pressure is 1.5kgf/cm2g and top temperature is 105degC. Reflux drum pressure is maintained above 0.6kgf/cm2g.
Just want to understand the importance of maintaining pressure in reflux drum via Hot bypass PDV? What factor decides the minimum value of pressure to be maintained in it?
How does variation of pressure via Pressure differential valve in reflux drum affects the top product quality(Light Naphtha).
