Contamination of seal oil

[boubb]

hi,

Direct contact of process seal oil inside the centrifugal compressor sealing system, causes the contamination of oil by dissolve of heavy components hydrocarbons ( C7 to C12 ) include in the row gas.

The caracteristics of the used oil are :
Flash point is approxmatively 200° C
Viscosity is 46 Cst
Temperature of degasing crank is ( 75 - 85 °C )

Is s there any other kind of oil synthetic or mineral
with same caracteristics of used oil that the missibility of (C7 to C12 ) can’t happen ?


thanks

You might ask about Dupont Krytox oil. Being a fluropolymer, hydrocarbons might not mix or be easily separable. You can ask Dupont engineering.
