RE: Strainer Deposit Analysis

You describe it as a white ash and the breakdown describes it as having a black appearance. Can you explain?

Hi,
The deposited material are on fuel gas strainer and fuel gas is refinery fuel gas. Main content is 50% H2, (H2S also present) and almost 3% olefin's in this gas.
I want to know from experience persons is this treatment problem or piping material problem (our case piping is CS)?
Thanks

RE: Strainer Deposit Analysis

You cant deposit "fuel gas" on your strainer. Most of you deposit is iron so maybe its a corrosion product e.g. FeS? If you pour HCl on the powder and smell H2S then its most likely the case.

Best regards

Morten
