Air Reciever/Dryer design
Air Reciever/Dryer design
(OP)
Everyone:
Was curious if there was a standard industry practice for a plant air system that puts the air dryer skid BEFORE a large Air Reciever, or AFTER the reciever? I have seen both designs in practice and heard rational for both, but was hoping someone had some insight on this.
Thanks!

RE: Air Reciever/Dryer design
On the other hand, the purpose of the tank is to store air to accommodate surges in air demand. High surge flows through a dryer will overload it and the air coming out will not be dry. From this viewpoint the tank should be after the dryer.
RE: Air Reciever/Dryer design
The instrument air receiver will obviously be installed downstream of the drier. The plant air receiver doesn't need drying, hence no drier.
The air receiver you have seen upstream of the drier is only buffer to prevent excessive pulsations from compressor hitting the drier. It is maily fitted with a PSV for the protection of the drier. If you have a constant dry air consumption and the drier is sized correctly, you don't need another tank downstream of the drier.
