Control Valves

During the engineering phase of capital projects, difficult budgetary and scheduling constraints can result in less than optimal control equipment selections. In critical valve applications, under-performing equipment can lead to serious inefficiencies in plant operation, increased costs and reduced production. Effective process control optimization requires an understanding of all components in the loop – measurement, controller and final control element.

Challenge:

Instability in fuel gas pressure supply to a co-gen gas turbine resulted in errati c turbine speed, power output decline and inefficient plant operati on. 


Solution:

Spartan performance optimization specialists analyzed the live system and determined the root cause. Recommendations were made for control valve modifications that allowed a swift return to stable fuel supply pressure and efficient turbine operation.
