Sharing of experiences and insights regarding excessive levels of highly acidic ferric ions in water in diesel hydrogenation units
Thread Content
Share technical experiences regarding excessive high-concentration acidic ferric ions in water in diesel hydrogenation units; it is best to clearly explain the solutions adopted and their effects
Installing an iron removal filter can solve this problem. What is the current flow rate?
What is the iron content at the inlet of the hydrogenation unit? Is it iron tetraoxide or iron oxide?
Is it related to water injection? Did less water injection lead to more severe sulfur corrosion? Was there an extra cycle of sampling for some time?
The filtration device can ensure that the iron content at the outlet is no more than 10μg/L
Is it air cooling or corrosion of the heat exchanger pipes?
