Regarding corrosion inhibitors, I’ve seen in the literature that the dosage is usually given in μg/g; but how is this converted into a flow rate in practical applications?

Is the quality of the oil and gas at the top of the tower calculated? What is generally the range for this volume in various factories? For water-soluble and oil-soluble types, what is the concentration used, and how many tons per hour? I hope the seniors will be kind enough to share their advice :)
Check the gasoline flow at the top of your tower. After selecting the injection amount, adjust it further based on the anti-corrosion conditions. Such as pH value, iron ions, etc.
I would like to ask how the injection volume is determined – what is the typical flow rate, and what are the amounts of corrosion inhibitor and ammonia used?
Is the g in the denominator the amount of gasoline at the top of the tower? I previously assumed it to be the total amount of distillates from the tower; 1 gram of distillates corresponds to about 10 micrograms of corrosion inhibitor
μg/g is 10 to the power of -6
Well, I know; it’s similar to ppm. What I’m more interested in knowing is the specific injection volume, as I need to select a pump. Taking corrosion inhibitors as an example, if the injection rate is 20 μg/g, then the amount of pure corrosion inhibitor required is approximately 20 g/t. With a flow rate of 30 t/h at the tower top, 600 g/h of pure corrosion inhibitor is needed. Generally, the corrosion inhibitor is mixed with the gasoline at the tower top, with a concentration of around 1%-3%; the injection rate of the corrosion inhibitor ranges from 20 kg/h to 60 kg/h. I’m not sure if my reasoning is correct
