Thermal Desalination Package Sediment Removal at South Pars Third Refinery

The third refinery of the South Pars Gas Complex (Phases 4 and 5) took an important step towards optimizing the performance of its thermal systems by implementing specialized sediment removal operations on the thermal desalination package by Abrizan Company in 1404. This project was carried out under the direct supervision of the refinery’s senior technical officials, and its results were officially declared satisfactory and approved.

• Location: South Pars Gas Complex Third Refinery (Phase 4 and 5 Units)
• System Type: Thermal Desalination Package
• Time of Implementation: 1404 AH
• Main Challenge: Sediment Accumulation in the Thermal System and Reduced Operational Efficiency

Technical Supervision at Standard Level

This project was implemented with the presence and supervision of three key technical officials of the refinery:

• Head of Operations (ensuring safe and continuous operation)
• Head of Technical Inspection (process quality control and safety)
• Manager of Water and Steam Unit (operational specialist approval)

This comprehensive supervision demonstrates the strategic importance of the project and the refinery’s trust in Abrizan’s expertise.

Abrizan's Specialized Solution: Safe and Efficient Sediment Removal

The use of advanced chemical washing methods appropriate to the type of thermal system sediments, the implementation of operations with minimal production downtime and without damage to equipment, and the use of a specialist desalination team with a history of implementing similar projects in refineries in the country were among the key features of this project.

Desirable results and official approval

After the operation:

The most complete removal of sediments from thermal surfaces and pipes

Return of system performance to the desired design conditions

Reduction of energy consumption and increased productivity

The project results were officially reviewed by the refinery's technical committee and were declared "desirable and approved"✅.

The desalination project for the thermal desalination package of the third South Pars refinery is an outstanding example of successful cooperation between industry and domestic experts. The official approval by the refinery’s technical authorities demonstrated the effectiveness of the water treatment methods and the unquestionable quality of the operations. This achievement paved the way for preventive maintenance and continuous optimization of the refinery’s critical systems.
