Chemical Cleaning of Heat Exchangers – Phase 1

Plant Shutdown – September 2025 | Peru

During the scheduled plant shutdown in September, the Lubritech Peru team successfully carried out the chemical cleaning of heat exchangers from the Ring Motor and Lubrication System of the SAG 1, Ball 1, and Ball 2 Mills of Phase 1, at a major mining company in Peru.

The main goal was to remove scale, sediments, and contaminants accumulated in the cooling and lubrication circuits, which affected heat transfer and overall equipment performance.
This work aimed to restore optimal operating conditions, extend system life, and ensure process continuity and safety.

Activities included draining, connection of recirculation systems, and continuous monitoring of technical parameters (pH, temperature, conductivity, and TDS), ensuring a controlled and safe execution aligned with technical and environmental standards.

✅ Results

The intervention allowed the recovery of the heat exchangers’ thermal efficiency, improving heat transfer, reducing operating temperatures, and stabilizing the lubrication and cooling systems.
All neutralization and responsible environmental management procedures for generated effluents were properly completed.

Congratulations to the Lubritech Peru team for their commitment, professionalism, and outstanding performance

25 Years of Leadership in High-Velocity Oil Hydraulic Flushing in Argentine Refineries.

During the recent Catalytic Plant Shutdown at a major refinery in Argentina, Lubritech Argentina successfully carried out critical high-velocity oil hydraulic flushing on the Blower Turbocompressor, the Gas Compressor, and the hydraulic systems of the plant’s valves.
This service is of vital importance: the Blower is the first rotating equipment to start up after the shutdown, and any delay in flushing could postpone the restart of a plant that produces over USD 500,000 per day.

Commitment to Standards and Continuous Improvement
To ensure flawless results and completion within schedule, we strictly follow ASTM D6439. This year’s job had special significance: 25 years ago, we performed the same activity in this plant, and since then, we have kept up with every revision of the standard, incorporating all improvements.
In 2000, the standard required a Reynolds number > 4,000, and we used a 150 GPM pump (as seen in historical photos).
The current version requires a Reynolds number > 10,000, so we deployed a 500 GPM pump (visible in the service video). This leap demonstrates our leadership, expertise, and ongoing technical evolution.

For this project, we worked with the refinery’s local technicians and also had the support of four specialized technicians from our External Services Department. We congratulate everyone for their commitment and attention to detail.

International Presence and Specialization
These services are not only performed in Argentina: our team provides high-velocity oil hydraulic flushing solutions throughout the Americas and parts of Europe, always working with Safety, Quality, and on time, following procedures approved by OEMs and end users.

Our specialization has made us a trusted partner for critical projects during plant shutdowns, ensuring equipment is ready to operate without delays.

A Touch of History
In the year 2000, the technical team was led by the person who is now the General Manager of the Sicelub Lubritech Group, a testament to our continuity, commitment, and passion for what we do.

High Velocity Oil Flushing at Olefins Plant in Portugal

From our company Sicelub Ibérico in Spain, we successfully carried out a major high velocity oil flushing project at an Olefins Plant in Portugal. This project highlights our ability to perform these specialized services anywhere in Europe, always ensuring maximum reliability during commissioning and a reliable startup of critical equipment.

During the shutdown and revamping, we performed three flushing jobs on main compressors:

  • 4-body Raw Gas Compressor: turbine replaced by motor, including two tanks (lubrication and seal) and a Run Down Tank.
  • Ethylene Compressor: installation of a new lubrication skid.
  • Propylene Compressor: addition of a new tank and replacement of turbine with motor, in compliance with European regulations for CO₂ emissions reduction.

In all cases, the lubrication systems are equipped with Thermojet purifiers installed in the tanks, with an approximate capacity of 8,000 liters each.

To achieve the required cleanliness levels, we circulated oil at high velocity for extended periods, especially through heat exchangers, where more contaminants usually accumulate. As a result, we reached very low ISO 4406 cleanliness codes, in compliance with ASTM D-6439-23, ensuring maximum lubricant purity.

This achievement was made possible thanks to the dedication of our technical team, with full support from our organization in Spain and Portugal.

We attach some photos of the work team and the filters used during the process.
