    Compressor Question

    I'm really just trying to conceptualize vapour compression for use as a reboiler in distillations, and had some mind blocks when it came to compression of the saturated vapour. You guys have been a lot of help!

    Compressor Question

    So is it possible at all to condense a gas by increasing the pressure past the saturation pressure? i.e. Is it physically possible to isothermally compress a gas using standard compressors?

    Compressor Question

    When compressing a saturated gas, what happens exactly? The temperature must rise to keep it at a saturated state - but what keeps the gas from simply condensing instead of the temperature increasing?

    Gas Headers

    When designing a gas distribution header system, does the order at which users are put in the line affect the system? This may be a stupid question... I'm not sure. I am thinking that because the pressure in the header is controlled upstream of the users, it doesn't matter what flow rate each...

    Confused on static vs. dynamic pressure

    Hello everyone, I am a new chemical engineering grad and trying to work my way through some of my first line sizing calculations. I was hoping someone could clarify for me the difference between dynamic and static pressure, and how the two are calculated. Also, how is the static pressure of a...

    Lighter Crude Feed in Crude Distilling Unit

    First you should consider caustic injection at the crude after the desalter. This will reduce the amount of chlorides at the boot of the overhead drum. You can use both NH3 and filming amines and target for a pH at the water that your chemical vendor will suggest. The tip of the story is to use...
