Introduction

Hydraulic oil separation is a process designed to remove impurities from hydraulic oil, restoring its original properties and ensuring it meets operational standards. By employing specialized separation techniques, contaminants like water, air, and solid particles are effectively eliminated, prolonging the oil’s service life and reducing the risk of component wear and failure. Regular hydraulic oil separation offers multiple advantages. First and foremost, it prevents the buildup of harmful substances that can cause corrosion, oxidation, and sludge formation. This not only enhances the oil’s lubricating properties but also contributes to maintaining the overall efficiency of the hydraulic system. Furthermore, hydraulic oil separation helps minimize maintenance costs, extend equipment lifespan, and reduce downtime, making it a crucial practice for industries relying on hydraulic systems.

Why is Hydraulic Oil Separation Important?

Oil testing serves as a diagnostic tool to evaluate the condition of the insulating oil used in transformers. By analyzing the oil’s composition and properties, experts can detect potential issues such as contamination, oxidation, or degradation. This enables early detection of problems, facilitating timely preventive maintenance or repairs.Hydraulic systems are the backbone of numerous industries, powering critical machinery and equipment used in construction, manufacturing, and transportation. These systems rely on hydraulic oil for power transmission, cooling, and lubrication. Over time, the oil can become contaminated with water, air, and particles, which can significantly impact its performance and the efficiency of the entire system. This is where hydraulic oil separation comes into play, providing a reliable solution to maintain oil quality and system performance.

Oil contamination can lead to various problems, such as reduced lubrication, increased friction, and accelerated component wear. Water, in particular, poses a significant threat as it can cause emulsification, leading to reduced oil viscosity and poor lubrication. Additionally, solid particles can cause abrasive wear on hydraulic components, leading to costly repairs and replacements.

Hydraulic oil separation is essential because it allows for the removal of these contaminants, ensuring that the oil remains in optimal condition. By using appropriate separation methods, industries can achieve cleaner oil, which translates to improved system efficiency, enhanced equipment reliability, and extended service life. This proactive approach not only prevents potential failures but also contributes to cost savings in terms of maintenance and replacement expenses.

Types of Hydraulic Oil Separation Techniques

Several techniques are employed to achieve effective hydraulic oil separation, each catering to different types of contaminants and operating conditions. The most common methods include:

Centrifugation: Centrifugation is a widely used technique that utilizes centrifugal force to separate contaminants based on their density. When hydraulic oil is spun at high speeds in a centrifuge, heavier contaminants such as water and solid particles are forced to the outer edges, while the purified oil collects in the center. This method is highly effective for removing water and solid particles from hydraulic oil.

2.Coalescence: Coalescence is a technique that involves passing the contaminated oil through a series of coalescing elements. These elements attract and merge small water droplets into larger ones, which are then separated from the oil due to their higher density. Coalescence is ideal for separating water from oil and is commonly used in systems where water contamination is a concern.

3.Filtration: Filtration involves passing the contaminated oil through a filter media that traps solid particles, dirt, and debris. This method is effective in removing solid contaminants and is often used in conjunction with other separation techniques for comprehensive oil purification.

Vacuum Dehydration: Vacuum dehydration is a process that uses vacuum pressure to remove dissolved water and gases from hydraulic oil. By lowering the pressure, the boiling point of water is reduced, allowing it to evaporate at lower temperatures. This technique is particularly useful for removing both free and dissolved water, as well as entrained gases from the oil.

Applications of Hydraulic Oil Separation

Hydraulic oil separation finds its application in a wide range of industries where hydraulic systems are used, such as:

Manufacturing: Hydraulic oil separation is essential in manufacturing industries to maintain the efficiency and reliability of hydraulic presses, injection molding machines, and other critical equipment.

Introduction to Viscosity

Importance of Viscosity in Lubrication

In lubrication, viscosity determines how effectively a lubricant can separate moving components, reducing friction, preventing wear, and minimizing energy loss. Using the wrong viscosity lubricant can lead to either inadequate protection (if too low) or increased drag and energy consumption (if too high).

For industrial machinery, oil and grease formulations are selected based on viscosity SI units and standardized measurement systems like ISO VG (Viscosity Grade) and SAE (Society of Automotive Engineers) viscosity grades.

Viscosity SI Units and Other Measurement Units

Viscosity is measured using several units depending on whether it is dynamic viscosity or kinematic viscosity.

Dynamic Viscosity (Absolute Viscosity) Units

SI Unit: Pascal-second (Pa·s) or milliPascal-second (mPa·s)

CGS Unit: Poise (P) or centipoise (cP), where 1 P = 0.1 Pa·s

Common Industrial Use: Centipoise (cP) is frequently used in lubrication industry applications.

Kinematic Viscosity Units

SI Unit: Square meter per second (m²/s)

CGS Unit: Stokes (St) or centistokes (cSt), where 1 St = 10⁻⁴ m²/s

Common Industrial Use: Centistokes (cSt) is the most widely used unit in industrial lubrication, with ISO VG ratings based on kinematic viscosity at 40°C.

Understanding Absolute Viscosity (Dynamic Viscosity)

Absolute viscosity, also known as dynamic viscosity, refers to a fluid’s resistance to shear stress. It measures the force required to move one layer of fluid over another.

Formula:

Where:

= dynamic viscosity (Pa·s or cP)

= applied force (N)

= area of the fluid layer (m²)

= velocity gradient (s⁻¹)

Dynamic viscosity is used to determine how a lubricant behaves under mechanical stress and is critical in applications involving gears, hydraulics, and compressors.

Understanding Kinematic Viscosity

Kinematic viscosity is the ratio of dynamic viscosity to the density of the fluid. It represents how fast a fluid flows under gravity.

Formula:

= kinematic viscosity (m²/s or cSt)

= dynamic viscosity (Pa·s or cP)

= density of the fluid (kg/m³)

Kinematic viscosity is widely used in industrial lubrication standards such as ISO VG ratings, which categorize lubricants based on their kinematic viscosity at 40°C

Viscosity vs. Kinematic Viscosity

While dynamic viscosity measures a fluid’s internal resistance to movement, kinematic viscosity considers both viscosity and fluid density. In lubrication, the kinematic viscosity-to-viscosity relationship helps in determining how a lubricant will behave under real-world operating conditions.

Coefficient of Viscosity Unit and Its Role

The coefficient of viscosity represents the relationship between shear stress and shear rate in a fluid. It is often synonymous with dynamic viscosity in Newtonian fluids. The coefficient of viscosity is crucial in industries where precise viscosity control is required for operations like metalworking, automotive lubrication, and hydraulic systems.

Viscosity Measurement Units and Techniques

Measuring viscosity requires specialized instruments that ensure accuracy in selecting the right lubricant.

Common Viscosity Measurement Techniques:

Capillary Viscometers (Ubbelohde, Ostwald) – Used for kinematic viscosity.

Rotational Viscometers (Brookfield Viscometer) – Measures dynamic viscosity.

Falling Ball Viscometer – Determines viscosity by measuring the falling speed of a ball through the fluid.

Redwood and Saybolt Viscometers – Used in petroleum industries.

Each method provides valuable insights into the viscosity behavior of lubricants under different conditions.

A critical oil reclamation project for the largest oil refinery with a capacity of 8 million tonnes per year in West Bengal, India.

Synopsis

The lube oil used in various industrial equipment such as pumps, compressors, turbines, blowers, turbo generators, recycle gas compressors, wet gas compressors, and coke cutting pumps had critical contamination levels initially. The problem was caused by poor maintenance by a previous service vendor, resulting in the presence of moisture and impurities in the oil tank. To address the issue, Minimac Operations and Maintenance Service (MOMS) carried out a timely service operation to help the plant bring down the moisture count and remove impurities from the oil tank. Before oil purification, NAS ≥ 12, Moisture ≥ 650 PPM; after oil purification, NAS < 5 and Moisture < 200 PPM This helped to improve the quality of the oil used in the equipment and ensure the smooth operation of the plant.

Problems

The oil was contaminated with moisture and mechanical impurities due to insufficient maintenance, which could lead to equipment failure and downtime. The presence of these impurities in the oil could also cause damage to the equipment, reduce its lifespan, and decrease its efficiency. It was essential to address this problem by implementing proper maintenance practices, such as regular oil changes, filtration, and moisture control, to ensure that the industrial oil is clean and free from contaminants. Failure to address this issue could lead to increased costs as well as production losses due to downtime.

Client’s Requirement

Feedback

Minimac believes in delivering the best experience to the clients with result-oriented project execution, hence, as a result, the project was extended further.

Team Minimac successfully executed a critical project to recondition the control fluid (two tanks of capacity 16 kiloliter each) for India’s largest energy conglomerate and coal-based power producer with a capacity of 4760 MW.

Synopsis

The plant was built and is in service as a thermal power generating station, in Vindhyachal. There was a problem with higher Total Acid Numbers (TAN), observed typically when moisture content exceeds the permissible range. They were facing difficulties in stable unit operation because of the sluggish and erratic behavior of the turbine governing system. It was a significant threat to unit outage and generation loss. The situation was examined by Minimac Operations and Maintenance Service (MOMS). Resin skid - Minimac- FS-20-TRIX- 8-25 ltr-1S-FRF-DOL was deployed to address the issue.

Before Oil purification, the TAN value was≥ 0.62 mgKOH/gm, NAS ≥ 8, and Moisture ≥ 1471 PPM. After Oil purification, the recorded parameters were TAN value = 0.08 mgKOH/gm, NAS ≤ 4, and Moisture ≤ 260 PPM. The major challenge faced during the execution was if we charged resin, TAN would reduce, but moisture would increase. So, an analysis was done and implemented to control the moisture first, then charged the second resin cycle. Minimac gave a 100% customized and balanced solution within time.

Problems

The tank capacity was 16 kiloliters, which is huge. The biggest challenge was to execute the project while the system was in operation. Water contamination bubbles were forming, leading to the fluctuation in NAS - as for moisture control, it was necessary to turn off the system. Resin charge in Ion exchange was done intermittently to control moisture increase, and our motto was to hold moisture below 500 PPM so we could plan for the next cycle of resin charge.

Client’s Requirement

To purify the control fluid.

To reduce the TAN value from 0.62 to < 0.10 mgKOH/gm.

To bring down the moisture level < 500 PPM.

Solutions

Resin skid - Minimac- FS-20-TRIX- 8-25 ltr-1S-FRF-DOL for NAS & moisture reduction was installed.

Before the oil conditioning process, the TAN ≥ 0.62 mgKOH/gm, which was reduced after oil purification to TAN ≤ 0.08 mgKOH/gm.

The Nitrogen generation unit (TMR 100) was deployed and installed at the client’s site.

For further improvement in TAN, the oil vapor extraction fan (OVEF) was throttled in the range of 70%, with the support of the user.

Minimac provided trained manpower and other consumables under the MOMS (Minimac Operations and Maintenance Service) offering. Minimac had given results far better than the KPIs.

The Minimac team successfully completed a critical flushing project in a big fertilizer company with a capacity of 4000 tonnes in Jharkhand.

Synopsis

An installation project was ongoing at the fertilizer plant’s premises. Newly built lube pipelines and tanks were to be flushed to remove the welding debris and other components left inside while fabricating the pipelines. The entire project was delayed due to a very slow flushing process. Minimac Operations and Maintenance Service (MOMS) team evaluated the situation and came out with a solution to expedite the flushing process. The project required flushing their two main compressors, i.e., PSE processed air compressor and carbon dioxide compressor

Problems

Proper flushing had to be done as the pipeline was newly fabricated; otherwise, it would have led to a major breakdown of the compressor, as the impurities would choke the blades and erode/damage the compressor. Other issues were to ensure proper calculation for variable pipe diameters, and if the oil goes to the rundown tank and overflows, 60-65 degree oil will fall, causing a huge mishap.

Client’s Requirement

Fast completion of the job to meet the project timeline.

Solutions

Minimac Systems examined the pipeline, which consisted of a low-pressure pipeline, high-pressure pipeline, and run-down tank.

A proper calculation was done as the work was a bit critical; any negligence could become a mishap

All parameters must be considered, including segment-wise flushing, hammering, thermal showering, etc.

At the end of the flushing, a mesh was installed to check if any impurities were present

Completing the flushing project was ensured as per ISO 18/15/12

Cost Saving

This plant managed to save:

Cost of import caused due to deficit of fertilizer.

CO2 e Saving

Benefits

The reliable operation of the system and trouble-free operation of machines.

Sustainable performance of manufacturing process.

Elimination of new compressor cost.

Avoiding the risk of fire and explosion.

Reduction in the possibility of product degradation due to lack of proper flushing

Timely execution.

Feedback

As a result of Minimac's excellent work, another assignment of a similar nature was assigned to them. Minimac achieved the OEM's request for no debris in the mesh.
