Abstract
Quench oil aging and its propensity to cause fouling may be evaluated by determining the amount of a precipitant necessary to cause the flocculation of polymer species present in the quench oil. The propensity of quench oil to cause fouling may be used as a basis to mitigate fouling in cracking processes.
Claims20
A method for reducing fouling from quench oil comprising:
- treating a hydrocarbon feed using a cracking process having a quenching step wherein:
- quench oil used in the quenching step has a known tendency to cause fouling;
- and
- the known tendency of the quench oil to cause fouling has been determined by measuring a tendency of the quench oil to precipitate polymeric species.
1 more element
A method for reducing fouling from quench oil comprising:
- treating a hydrocarbon feed using a cracking process having a quenching step, and introducing an additive to reduce fouling to the cracking process based upon a tendency of the quench oil in the quenching step to cause fouling which is determined by measuring a tendency of the quench oil to precipitate polymeric species.
