    Fuel Gas Coalescer Filters

    Yes, this is exactly what we have. And yep, the flow does go from bottom to top. You do have me intrigued on the slug idea though. Help me think through that please. What would cause a slug to be formed and travel to the filters? I have attached the documentation I have on the coalescer below.

    Fuel Gas Coalescer Filters

    I agree. It doesn't seem like there should be that much variation in DP across the filters, especially after such a short period. Can fatigue cause the filter to fail? As far as how the system works: Our fuel source has liquids that sometimes need to be knocked out. This is accomplished by our...

    Fuel Gas Coalescer Filters

    Below is the DP plot of the system. We changed the filters in August of last year and the DP increased until it was around a max of 9. The filters are supposed to have a burst rating of 32 psi, so we were nowhere close to that. I have also attached the filter literature as well. The liquid gets...

    Fuel Gas Coalescer Filters

    I was definitely on the same page with you there on the brief pressure upset event, but it looks like we have a trend on the DP gauge in our software showing the entire operating time. Looking at the trend, it doesn't appear it even came close to the prescribed burst pressure. Wouldn't we see...

    Fuel Gas Coalescer Filters

    Hi all. At the site I am working at we have a fuel gas coalescer which keeps having filter media burst before the Cartridge Burst Pressure DP is reached. Any ideas or insights on to why this may be happening? The burst pressure dp is significantly higher than what we reach.

    Deaerator Usage In Power Plants

    Have any of you fellow engineers heard about or seen a push to no longer use a deaerator for feedwater? Have the dissolved gas standards changed where they are no longer necessary?

    Combined Specific Gravity of a Mixture of Liquid and Gas

    Hi, all. I am currently working on a problem where we have a flow in a line that is about 50% liquid and 50% gas. I know the specific gravity of the liquid, but always assume a specific gravity of 0 for the gas. How would I go about calculating the specific gravity of the combined contents of...
