I’ve been working on a system that consists of a tank (at environmental pressure), centrifugal pump (usual operation flood rate is within 28 to 46 M3/H, during start up to 100 m3/H), and a column around (2.4 BARG) as the end destination. Earlier than the column, there’s a heat exchanger that has max shape pressure of 8 BARG.
Over the pump, there’s a spillback to the sucking of the pump. In this spill back there’s a force control valve that is normally set to 7-3 BARG during startup to stop pressure spikes, harmful to the heat exchanger. Thus, this control is needed. In order to stop overheating due to the spillback via the pump, I’ve changed the reflow side to the through the container with A 4 in line. Though, now the issue is that the resistance via [url=https://www.kplokusa.com/automatic-recirculation-valve/]the Automatic recirculation valve[/url] makes pressure drop and therefore the fluid can’t go up to the container (elevated above 8 M from the pump). It changes state.
