Hydrocracking Scale Inhibitor


This Hydrocracking Scale Inhibitor also know as  anti-fouling agent for hydrocracking unit  is used for preventing scaling at the heat exchanger, reactor, and pipeline of hydrocracking unit in the refinery.


a.It has no components(such as metal and so on)which have bad effects on the activity of hydrogenation catalyst, product distribution, and product properties.

b.Low ash content , lest cause reduced porosity on catalyst bed layer, increased bed pressure drop .

c. The injecting amount is less, but the scale inhibition rate is up to more than 92%.
