The issue of adding passivators
Thread Content
What is the main factor used to determine the amount of passivator to be added to the catalytic device? May I ask, dear colleagues from your company, what is the dosage of passivator used?
The amount of passivator used is determined based on the heavy metal content in the catalyst, which helps to protect the catalyst and its activity to a certain extent.
Is there any percentage? Heavy metals on passivators and catalysts
Generally, the ratio of hydrogen to methane in dry gas is usually <1.2, which is sufficient
What was said upstairs is correct; by checking the ratio of hydrogen to methane in the dry gas, our target is ≤1.1, and if this value is exceeded, we increase the amount of passivator injected.
If the hydrogen content in the dry gas is higher than that of methane, does that require an increase in the amount of passivation agent injected? Is the effect significant after increasing the volume?
Based on the ratio of hydrogen to methane in the dry gas, the value is 1.12; if this value is higher, the amount of passivator injected must be increased
The hydrogen/methane content in our dry gas is above 2%, and the effect of injecting light passivation agents does not seem significant either
Is the content of heavy metals in your balance agents quite high? What are the levels of nickel and vanadium respectively? If the heavy metal content in the catalyst is high, increasing the amount of metal passivators added won’t have much effect
By observing the changes in the metal content of the crude oil and the hydrogen/methane content in the dry gas, along with the technical specifications for passivators
