Dear all,

What are the experiences in wet gas compressor fouling?
Our FCC unit employes turbine driven centrifugal compressor that suffers from severe build up of "polymerization" material on the rotor parts. I guess that this material is product of polymerization of olefins in wet gas stream. This material sticks to the rotor surface causing debalance and wearing of the rotor itself.
Does anyone have experience in water or oil wash systems? I have heard some cases of inhibitor dosing to prevent polymerization? Is this inhibitor effective in gaseous phase?

Thanx in advance

Hello Megamass,

How do you know it is a polymerization problem? Have you analyzed compressor deposits? Is it completely organic fouling, or you have certain ammounts of inorganic compounds (catalyst particles, NH4SH, NH4Cl etc.)?
