Gas-liquid scrubbers rely on level control systems to maintain an appropriate liquid level within the vessel. In natural gas service, these control systems are subject to harsh environments and failures are commonplace. This presentation discusses an ongoing project for the GMRC to investigate failures related to scrubber level control systems and to identify improvements to these systems. In this work, failure reports from one operator were analyzed and the component(s) that failed most often were identified. Subsequent work to identify and evaluate alternative level controllers is discussed and the design of an externally mounted ultrasonic level switch is described.
