Repair of connecting rod and modification of crosshead

The Indian Oil Corp. Ltd. (IOCL) in Mathura, India, repeatedly struggled with its compressor, which often failed. Complications arose when the third-stage pin and the small end bush seized up three times, preventing IOCL from restarting the compressor.

These circumstances forced them to operate the plant without a standby compressor. IOCL turned to Burckhardt Compression to solve the problem. As a part of the troubleshooting, repair and modification of the components were carried out. Since then, the compressor has operated properly without any issues.

We sincerely appreciate the support of Burckhardt Compression. As a part of troubleshooting of a compressor at our hydrocracker unit, they supervised the refurbishment of the 3^rd stage connecting rod and crosshead. Since the compressor was taken into line, it has run perfectly. Burckhardt Compression gave us valuable hints on how to handle the system, which was very important and useful for us.
