Filtration of hot oil heating medium

Filtration of hot oil heating medium

(OP)
Hi!

I'm a mechanical engineering student working on a natural gas production plant (Ormen Lange, Norway).
The system we are working on is the heating medium part, containing pumps, heat exchangers, furnace, filters and expansion tanks.
We just started and so far we have a pretty good idea of what to do except the filter part.

We are to size two suction filters, one for thermal oil(1), and one for water/hot cooling medium(2).
The information we know now is that a 5% slipstream goes though filter 1(about 79,3 m^3/h), and 10% slipstream through filter 2(unknown flow at the moment).
We also know that the filtration grade for the hot cooling medium is 80 micron.
Both are likely some kind of massive cartridge filter housing, like a strainer.
And that's basically what we know.

So I'm looking to find out where to start. Where i can find some good info on filter requirements for this kind of system? :) I cant seem to find any good info on google.

A good thermal oil supplier will gladly provide best practices information like this. That's how I get it.

Good luck,

Technically, the glass is always full - 1/2 air and 1/2 water.

Thanks for the help.

Gotta be honest, I didn't even know what i was asking when I wrote the thread, but now I kinda know what i'm looking at and have some good sources. I found the hot oil strainer to be pretty large, over 2m tall and 1m wide with 20" pipe connections.

I will contact a thermal oil supplier and ask for some data.
