Method of mitigating fouling and reducing viscosity in primary fractionators and quench sections of ethylene plants |
摘要 |
A method is disclosed for mitigating fouling and reducing viscosity in primary fractionators and quench sections of ethylene plants by adding to a hydrocarbon stream a mono and/or a polyalkyl-substituted phenol-formaldehyde resin having a weight average molecular weight of from about 1,000 to about 30,000 and at least one alkyl substituent containing from about 4 to about 24 carbon atoms, which alkyl substituent may be linear or branched.
