Performance Improvement Case Study for Gas Turbines

This case study presents the performance improvements achieved by a New Jersey cogeneration power plant using Mobil DTE 932 GT oil and Solvancer technology. The document outlines the situation where the plant aimed to enhance its maintenance process for GE Frame 7EA gas turbines, achieving over 57,000 hours of operation without varnish. The previous method involved a lengthy oil change process that took approximately 108 hours per turbine. The recommendation included using an oil soluble cleaner instead of the system cleaner and integrating Solvancer technology, which led to a reduction in oil change time by more than 70% and a decrease in waste oil by over 25%. The impact of these changes resulted in significant cost savings exceeding $100,000 and reduced maintenance hours by 72%, demonstrating the effectiveness of the proposed solutions in maximizing productivity and efficiency in turbine operations.
