    The best solution would be to exhaust into a hotwell, below the liquid level. Just make sure you don't submerge the exhaust pipe too deep or you will get excessive back-pressure. If there is no sump/hotwell, you are best off pointing the discharge upwards, and then have a drain off the bottom...

    Eductor calculations

    information required: 1. Motive fluid and pressure... given as 150 psig steam. 2. Suction fluid type and pressure + temperature. Say air at 14.5 psia? 3. Expected flow rate of suction gas, in #/hr. 4. Discharge pressure. Say 15.5 psia? That will enable any vendor to specify the ejector...

    Pressure drop software

    Can anyone recommend some good software to accurately calculate pressure drop for steam over pipelines? I don't mind spending for it, but it must be able to take into account some pretty complex geometry. The major packages like Aspen have thousands of fluids that I don't need. thanks!
