Corrosion inhibitor/Filming Inhibitor is used at crude distillation column overhead line to protect overhead line.
we have carbon steel overhead line(usually used in maximum refineries).Related to Corrosion inhibitor i have a following questions:
1. We prepare 4 % concentrated solution with kerosene. Is any criteria use for solution strength or either it is totally dependent on user and chemical vendor/supplier?
2.Vendor suggest to dose 6 PPM Corrosion inhibitor, Is dosing concentration will remain same or it depends upon the condition like Salt content in crude, PH, chloride, iron of tail water etc.?? If any criteria then how we adjust/Manipulate dosing with respect to changing conditions.
Further more,how much area will protect by corrsoion inhibitor.this will protect Line only?or also air cooler and trim cooler as well.?
