Selection of flow rate for the vent silencer
Thread Content
We are using KDN2000 air separation equipment; why is a nitrogen vent silencer with a flow rate of 1300 being used? Logically, it should be 2000 or higher, right? Please help explain this – I’m waiting online. Also, are there any regulations regarding the flow rate of the silencer? How is the flow rate specified?
Is the unit of 1300 volumetric flow rate or standard-condition flow rate? ~~Furthermore, during purification and normal production, the exhaust volume does not reach 2000 Nm3/h; therefore, manufacturers may consider reducing equipment costs by choosing this model of silencer~~
Yesterday afternoon was a bit busy. Our air handling capacity is 5800 m³/h; we produce 2000 m³/h of nitrogen (while they use a vent silencer with a capacity of 1300 m³/h). The amount of contaminated nitrogen generated is around 1300 m³/h (whereas they use a vent silencer with a capacity of 2300 m³/h). Approximately 2300 m³/h of contaminated nitrogen goes from the main cooler to the vent (compared to their 2000 m³/h figure). It seems that it’s clear they have installed the wrong equipment.
By your reasoning, the exhaust silencer must have been installed incorrectly.
