Dear all,

In some articles, foaming factor 0.8 is used for a new depropanizer design. Is it too low for existing depropanizer rating? How about 0.9 or 1.0 (non-foaming)?

Any good suggestion?

Many Thanks

System factor of 0.8 sounds too pesimistic for a depropanizer tower - more likely it is closer to 0.95 and assuming moderate pressures (<15 bar). Stanley Walas in his book "Chemical process equipment" classifies hydrocarbon fractionators into non-foaming systems (SF=1) while systems with SF==0.85 belong to moderate foaming category (e.g. oil absorbers, amine and glycol regenerators etc.)

Attached is the reference table from GPSA Databook.
