Reduction of the TAN value of the control fluid from 0.23 to 0.08 mgKOH/gm
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.
