Chemical cleaning of the thermal desalination package of the 8th South Pars Refinery | Efficiency leap to double with Mitreh solution

In 2022, the 8th Refinery of the South Pars Gas Complex (Phases 20 and 21) was facing a critical challenge in its thermal desalination package. The accumulation of resistant sediments had minimized the efficiency of the system. By implementing specialized sediment removal operations and using Mitreh solution, the expert team of Abrizan Company not only solved this crisis, but also set an unprecedented record in restoring the performance of thermal systems: an increase in efficiency by almost two times!

Operational Crisis: Thermal Desalination Efficiency Collapse

Pre-operation Status:

• The thermal desalination package was facing severe sediment accumulation
• Significant reduction in system efficiency to less than 50% of design capacity
• Increased energy consumption and risk of freshwater production shutdown

Technical Risks:

• Damage to thermal pipes due to hard sediments
• Increased repair and maintenance costs

Transformational Solution: Abrizan Expertise + Mitreh Power

Sediment Removal Operations in 1401:

• Performed by Abrizan’s expert desalination team with a brilliant track record in Pars refineries
• Exclusive use of Mitreh’s scale removal solution with advanced formulation

Technical Advantages:

• Removal of hard and resistant sediments without damage to equipment
• Complete washing of thermal surfaces and the space between the pipes
• Operation with minimal production downtime

Surprising Results: Efficiency Doubles

After From the operation:

• Impressive output:

• Emptying a large volume of sediment from the package

• Improved performance:

These results proved the extraordinary efficiency of Mitreh solution in restoring systems in crisis.

Strategic Achievement: A Model for Preventive Maintenance

The success of this project led to a strategic decision by the refinery:

• Placing periodic desalination plant flushing on the official agenda
• Selecting Mitreh solution as the standard solution

This policy change demonstrates the refinery’s complete trust in Abrizan’s expertise.

The desalination plant desalination package desalination project at the 8th South Pars Refinery was a turning point in the maintenance of the thermal equipment of this complex. The intelligent use of Mitreh solution not only doubled the efficiency of the system, but also created a model for preventive maintenance in the entire complex. This success proved the transformative power of Abrizan’s expertise in the Iranian oil and gas industry and showed that reviving crisis-ridden systems with scientific solutions is equivalent to replacing new equipment!
