Q & A > Question Details
Is there a way we can assess VGO Hydrotreater is running at Aromatic saturation equilibrium or still scope to increase Aromatic saturation by increasing catalyst volume? We are looking for revamp options of existing unit. Since operating pressure cant be changed to increase aromatic saturation, the only option is to add catalyst by introducing new reactor bed. The question and what I need to prove is that increasing catalyst volume improves the Aromatic saturation. This can be done by proving the current unit is not running at Equilibrium controlled all the times. During EOR conditions, it may reach equilibrium controlled because of high WABT. I need some literature on this. Can anyone share your thoughts?

Finding out the UOP K factor or Refractive Index of VGO feed and VGO product will help in judging the Aromatic content of hydrocarbon , by simple physical testing. Using SMS 2783 method can help in quanitifying the Aromatic content in VGO feed and product streams.

The comparative tests can be carried out in pilot scale or bench scale lab reactors that are available at Indian Institute of Petroleum, Dehradun or IOCL at Faridabad, India

Reducing LHSV in the running plant (100KBPSD) is very difficult to take approval. I need to convince my management first if there is a benefit and can proceed the test run. If the test run is successful, we are planning to go for a new additional reactor.

Adjust your parameters to match your future operation by performing a 72 hour test run that includes reducing the feed rate. Run PONAs on feed and product before and during test run. The effect of increasing the quantity of catalyst for the future operation will be evident.
