Cost Effective Re-Engineering Of A Propylene Compressor String.
Abstract
The discussed rerate method will provide users of turbomachinery with a new, cost/leadtime saving approach to plant upgrades. Although rerates of existing turbomachinery are common, this approach is unique in that the rerate was not performed by the original equipment manufacturer (OEM), yet it involved the utilization of existing aerodynamic hardware instead of the more common situation where all internals are replaced. This involves extensive engineering and design with limited data and increased cooperation between the rerate engineer and the end user. However, the resulting savings have proven to be worth the effort as evidenced by the project discussed. The following key areas of the project are covered in detail. • Project definition and quotation phase • Aerodynamic modelling • Design drafting • Manufacturing and assembly process • Operating performance from startup to present The methods used and the lessons learned in each of the above areas are discussed with the intent to provide turbomachinery users with a detailed example to follow in pursuing the savings that are available through this rerate process.
