Abstract :

In industrial plants such as gas refinery, sustainable production is a top priority. The cooling pump plays an essential role in a gas refinery. If the pump is out of service (and if the replacement pump is not ready), the refinery will be shut down immediately. Therefore, the sensitivity of this equipment is very critical in terms of operation and process and should be maintained in the shortest possible time. The status of this equipment is monitored regularly using vibration technique. In a period of time, after the vibration analysis, a decision was made to modify the base plate of the pump as well as to reduce the stress; piping arrangement of the pump was redesigned and modified. These modifications resulted in a reduction in vibration rate from 8 mm / s to 5 mm under new conditions. Also, in order to investigate the effect of fluid behavior on pump performance, in a separate project, flow fluid was simulated by computational fluid dynamics (CFD), within the impeller and pump casing.
