Considerations in the Capacity Uprating of an EOR HRSG

In enhanced oil recovery operations, the steaming capacity of a heat recovery steam generating unit is limited by the available energy provided from the gas turbine generator, however, there are a number of other component parameters that limit the thermal and mechanical performance of any specific heat recovery steam generator. These additional parameters reside on both the flue gas side and water / steam side of the heat recovery steam generator.Repetitive failures of steam generator components are evidence of damage mechanisms that are active during operation. Some of these damage mechanisms are explored to determine the immediate impact in up-rating the steam generators to higher capacity throughput and also, on longer term reliability. A resulting finding of this study examines the efficacy of using P22 low alloy piping in lieu of carbon steel piping to address flow accelerated corrosion.Copyright © 2016 by ASME
