I have a facility set up as shown in the attachment. It is a crude oil pump station. Oil comes in, it is metered and it is pumped to another facility.
We have valves on the suction and discharge side of the pump. To account for thermal relief we have installed a TRV on both the suction and discharge piping.
Now, is it acceptable to discharge a TRV to the suction side of the pump as shown in the diagram attached? I know that a better option is a suction vessel or tank, but we don't have either at this facility. The suction piping is around 200 ft long.
Has anybody seen an arrangement like this? What is the norm.
Thanks.
