Modernization of centrifugal compressors by the integration of new generation magnetic bearings.

Abstract

This study highlights the economic and operational advantages that the use of magnetic bearings in centrifugal compressors within the oil and gas sector can provide. The techno-economic evaluation shows a 16.64% reduction in maintenance costs. This reduction represents total savings estimated at approximately 673,372,329 DZD over the compressor life cycle. The analysis also indicates a 26.74% reduction in the overall life cycle cost. This result demonstrates a significant improvement in the system’s overall profitability. The total financial benefit is estimated at 1,003,854,999 DZD, confirming a positive long-term economic impact. These savings are mainly due to the elimination of additional oil lubrication systems. They are also attributed to the reduced frequency of replacement of wear-prone parts and maintenance operations. Furthermore, magnetic bearings enhance compressor reliability and availability by reducing friction, vibration, and wear. In summary, this technology improves performance, lowers total cost of ownership, and increases industrial efficiency.
