Anyone ever have experience with something like this? We want to spray steam into a glass-lined tank through a 2" dip leg. The dipleg points straight towards the bottom head of the tank, which is about 2 ft under the dipleg. The pressure at the end of the dipleg where it enters the tank...

I should have been clearer; I was comparing a lab batch sep funnel to a lab scale continuous decanter. The continuous decanter in the lab actually has a little less interfacial area than the sep funnel. Comparing the lab continuous decanter to the plant continuous decanter, they generate...

Good discussion, thanks for the responses. The side reaction to form solids is slowed by reducing temperature, so this might be a viable approach, but I'll have to put some cooling in which will add cost. Some observations from the lab; if I use a sep funnel and separate batchwise with about...

Sorry if this is a double post, my first one vanished. Gravity will work for this. In the past, two decanters have been tested on this stream. One was vertical with 1 hr res time for heavy, 30 min res for light. The other was horizontal, with more res time than the vertical. The problem is...

Thanks for the responses. Here's some other info on the application: Both Light and Heavy are products that will be recovered. The 2 phase mixture is not emulsified; it separates easily into 2 clear phases in about a minute or less in a 500 ml size bottle. Currently, the stream of the 2...

It's been awhile for me; I have an application where it's necessary to separate 2 immiscible liquids with a contact time of < 5-10 minutes. A centrifuge comes to mind, but would there be any other technology out there worth looking into, such as coalescer's? A decanter requires too much...

It was my first post and I'm very happy I wrote it...I ended up with a lot more information and responses then I expected. Thanks for your replies. Pete

I don't know anything about build-up and discharge of electrostatic charge, so this may be a dumb question; but can a flowing gas generate it's own static charge that might later dissipate providing an ignition source?

I see in the literature for handling hydrogen gas that there's often a warning that hydrogen can &quot;self ignite&quot; when allowed to spray through a nozzle or leaking flange. I'm trying to understand the mechanism of this self ignition. I did see some previous discussion on this topic...
