Minimac Systems Pvt. Ltd.

  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...

  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 mgKO...

  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 vari...

  Team Minimac successfully executed a critical project to re-condition the control fluid (tank capacity 16 KL) for a 2*600 MW coal-based thermal power plant in Chhattisgarh. Synopsis The plant establishes, operates, and maintains a thermal power generating station in Chhattisgarh. 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 generation loss and unit outage. The situation was examined by Minimac Operations and Maintenance Service (MOMS). Three machines - Nitrogen Blanketing TMR unit (100 LPM), Oil purification MLC-LVDH-TRIX (50 LPM), and TAN reduction— Resin filter modified in cartilage format were deployed to address the issue. Oil Purification TAN Value NAS Value Moisture Before Oil Purification 0.23 mg KOH/gm 10 678 PPM After Oil Puri...

Critical project successfully executed for ISO 9001 Certified - Millenium's shipbuilding yard under the Ministry of Ports, Shipping, and Waterways (Defence Sector). Synopsis The maritime-related facilities in the port city, the first enormous greenfield shipbuilding yard located in the state of Kerala, faced significant oil degradation issues affecting the overall functioning of the India's first Indigenous Aircraft Carrier (IAC), which led to the abrasion of the machines. 49k liters of oil were required to be purified and stored in two different tanks; the leading service tank had 22k liters of oil, followed by 27k liters of oil in another. Due to the contamination and degradation of the oil, the plant faced issues in wear and tearing of the machines that would lead them to machine breakdowns. Minimac provided FS225 and FS150 Oil Filtration Systems , which helped infiltrate the gearbox lubeoil. Also, testing the oil transparency was equally crucial so that no particles left co...
