Hello!
I have to insert a coalescer filter plant. I must provide the instrumentation for that filtre: control valves and level transmitters.
In this filter the mixture comes from two gas streams:
1. - A gas stream that carries oil from a compressor plant and
2. - A gas stream that carries glycol from a dehydration plant (TEG).
In this situation: Is the filter coalescer is the best option?, What kind of instruments should be placed?: If you use floating, what density should I expect?
Thank you very much for the help!

moab,

A Filter-Coalescer is the best choice for separating liquid from gas carrying fine liquid mist and where gas is required to be bone-dry for a downstream application. One application would be fuel gas fed to a gas turbine.

As far as instrumentation scheme is concerned, refer the link below for a P&ID scheme for fuel gas conditioning which includes Filter-Coalescer.

Hope this helps.

moab,

Coalescer filters are designed to remove any type of Liquid and Solid Aerosols. So you have selected a good application for removal of compressor oils and TEG. There are two distinct phases in your case, Oil Phase and TEG Phase but your filter vendor will design for only one phase. What i have seen from the Filter Vendors' sizing sheets that they usually consider an oil phase as it gives the most conservative results.
