Overview
INDION refinery process-chemical programmes address treatment needs in crude desalting and downstream refinery units. The current portfolio page identifies emulsion, rag-layer, foam, corrosion, fouling and deposit control as programme objectives. Chemistry is selected for the crude, process conditions, metallurgy and operating target.
Speciality Chemical Treatment Programmes for Water and Process ApplicationsPDFDownload Applications
Crude desalter
Desalting, emulsion and rag-layer management.
CDU and VDU
Treatment needs in crude- and vacuum-distillation operations.
FCCU and downstream units
Unit-specific corrosion, fouling, deposit or foam control.
Overhead and condensation circuits
Treatment based on process water chemistry and corrosion or deposit risks.
Refinery water and effluent
De-oiling, clarification and sludge treatment.
Process use and chemical role
Applications by refinery unit
| Process stage or system | Chemical or operational role |
|---|---|
| Crude desalter | Treatment programmes support desalting and oil-water separation, including management of emulsion and rag-layer conditions. |
| CDU and VDU | Programmes address corrosion, deposits and fouling in crude- and vacuum-distillation operations. |
| Overhead and condensation systems | Treatment is selected for the water chemistry, process conditions and corrosion or deposit risk in the circuit. |
| FCCU and downstream units | Process programmes address unit-specific fouling, deposits, foam or corrosion risks. |
| Refinery water and effluent circuits | Polyelectrolytes may be selected for de-oiling, clarification and sludge treatment in refinery water streams. |

Benefits and intended outcomes
OUTCOME 1
The current portfolio page identifies emulsion, rag-layer, foam, corrosion, fouling and deposit control as programme objectives.
OUTCOME 2
Polyelectrolytes may be selected for de-oiling, clarification and sludge treatment in refinery water streams.
OUTCOME 3
The correct treatment area and product depend on the unit and stream.

Selection and implementation
SYSTEM-SPECIFIC SELECTION
Review the unit, process stream, crude or water analysis, operating data, metallurgy, current treatment and target outcome.
FAQs
Which refinery units are covered?
The current page lists crude desalting, CDU/VDU, FCCU, overhead and condensation systems, and downstream process units.
Do all units use the same chemical?
No. Treatment depends on the unit and the specific process problem.
What information is needed for a review?
The relevant stream analysis, crude and operating conditions, unit details, metallurgy, current treatment and target outcome.
