These problems led to frequent compressor shutdowns and wasteful energy consumption. A system integrity analysis by Burckhardt Compression identified inappropriate materials and designs as the root cause of all problems. The two compressors were operated in parallel without any standby compressors as a back-up. The company was experiencing unexpected compressor shutdowns, decreasing output, high maintenance costs, challenging dryrunning applications, high leakages, reduced gas flow, and temperature issues. Burckhardt Compression’s team of experts conducted a complete compressor system integrity analysis onsite, which showed that the cylinder liner was damaged due to inappropriate piston ring material. Burckhardt Compression’s solution included upgrading the piston/packing rings to Persisto 850, a material that has been specially developed for sealing applications in dry-running reciprocating compressors. The piston rod was repaired, applying proper coating material and roughness, and all other components were refurbished at Burckhardt Compression’s local service centre. As a result of the solution provided by Burckhardt Compression, energy savings were achieved by avoiding internal losses, and emissions were reduced. Internal leakage was eliminated, and nominal gas flow was restored. There was a substantial increase in wear parts’ lifetime, and a reduction in maintenance costs. Burkhardt Compression also had a local expert team on hand for immediate support. The customer said: “We were struggling with the short lifetimes of the piston rod seals and packing rings. Burckhardt Compression’s solution with the right selection of material helped us to increase compressor availability significantly. Thanks to their analysis, we now better understand the component failure modes. Our second compressor, which was plagued by the same issues, is now being revamped by Burckhardt Compression too.” By both identifying the root cause of the problems faced by the chemicals company and providing a comprehensive solution, Burckhardt Compression helped the chemicals company to optimise its energy efficiency, reduce emissions, and increase its profitability.
