Abstract
Non-high solvency dispersive power (non-HSDP) crude oil with increased fouling mitigation and on-line cleaning effects includes a base non-HSDP crude oil and an effective amount of resins isolated from a high solvency dispersive power (HSDP) crude oil, and method of making same. Also, methods of using such non-HSDP crude oil for on-line cleaning of a fouled crude oil refinery component, for reducing fouling in a crude oil refinery component, and in a system capable of experiencing fouling conditions associated with particulate or asphaltene fouling.
Claims33
A method of making a non-high solvency dispersive power (non-HSDP) crude oil with increased fouling mitigation and on-line cleaning effects, comprising:
- providing a non-HSDP crude oil;
- providing resins isolated from a high solvency dispersive power (HSDP) crude oil;
- blending the non-HSDP crude oil and an effective amount of the resins to form a blended crude oil.
A non-high solvency dispersive power (non-HSDP) crude oil with increased fouling mitigation and on-line cleaning effects, comprising:
- a base non-HSDP crude oil;
- and
- an effective amount of resins isolated from a high solvency dispersive power (HSDP) crude oil.
A system capable of experiencing fouling conditions associated with particulate or asphaltene fouling, comprising:
- at least one crude oil refinery component;
- and
- a blend in fluid communication with the at least one crude oil refinery component, the blend including a base crude oil and a non-high solvency dispersive power (non-HSDP) crude oil with increased fouling mitigation and on-line cleaning effects, wherein the non-HSDP crude oil with increased fouling mitigation and on-line cleaning effects comprises:
- a non-HSDP crude oil;
- and
- an effective amount of resins isolated from a high solvency dispersive power (HSDP) crude oil.
A method for on-line cleaning of a fouled crude oil refinery component, comprising:
- operating a fouled crude oil refinery component;
- and
- feeding a blended crude oil to the fouled crude oil refinery component, the blended crude oil comprising a blend of:
- a base crude oil;
- and
- and a non-high solvency dispersive power (non-HSDP) crude oil with increased fouling mitigation and on-line cleaning effects, wherein the non-HSDP crude oil with increased fouling mitigation and on-line cleaning effects comprises:
- a non-HSDP crude oil;
- and
- an effective amount of resins isolated from a high solvency dispersive power (HSDP) crude oil.
A method for reducing fouling in a crude oil refinery component, comprising:
- providing a base crude oil;
- providing a non-high solvency dispersive power (non-HSDP) crude oil with increased fouling mitigation and on-line cleaning effects, wherein the non-HSDP crude oil with increased fouling mitigation and on-line cleaning effects comprises:
- a non-HSDP crude oil;
- and
- an effective amount of resins isolated from a high solvency dispersive power (HSDP) crude oil;
- blending the base crude oil with the non-HSDP crude oil with increased fouling mitigation and on-line cleaning effects to create a blended crude oil;
- and
- feeding the blended crude oil to a crude oil refinery component.
