Compressor Discharge to Recevier Pipe

Does it matter if the receiver is in-line or off-to-one-side, then? It only needs one pipe and not two, surely?

when considering water condensate from the compressor i think it may matter? because when using this arrangement condensate can go directly to the load equipment. please correct me if wrong?

Is it working the way it is? Either set up is going to allow condensate to go to load equipment without an in line air drier/moisture separator. Do a CR4 search on air driers/ compressed air condensation, etc. lots of good info. If it's working as is, I can't think of any benefit to dismantling everything and changing it.

This is how is the current set up being installed. there is also drain trap installed at compressor discharge but it seems that its not functioning.

If i re-route the pipe from tee fitting to the top of reciever and put trap at recevier bottom would this get rid of condensate that is going to the load equipment?

There should be a pet-cock valve or something similar on the bottom of your receiver. This is an essential item. You can either leave it cracked a little bit to allow moisture to escape as it falls to the bottom of the tank, or open it several times a day to release condensate. This is all you need at the bottom of the receiver. In regard to any remaining condensate reaching load, an inline air dryer installed between your tee and load should do the trick. If you are going to rework your receiver, I would run straight line to inlet on receiver from compressor, followed by straight line from outlet of receiver to load, both toward the top of the receiver to help eliminate condensate, with inline air dryer installed prior to load if condensate is still a problem.

One thing more i feel it can cause more condensation.

Before the load equipment there is a pressure regulator. i suggest it would be better to install the drain trap after that pressure regulator and before the load since temperature reduction after the regulator may still result in additional moisture which needs to be released from the system.

I can't tell you for sure if that would help, but it certainly wouldn't hurt. All of this depends on how sensitive your load equipment is to moisture. I would contact the manufacturer of load equipment and find out how dry air needs to be. You can spend $100 for a decent air dryer up to thousands for moisture removal and air purification. I'm throwing out ideas based on what I know, but I can't guarantee that what I'm saying is going to work in your particular situation. I sure wouldn't want to see you wreck a piece of equipment by configuring your system based solely on my advice.

You do not want to put a drier/trap in the load line as it will impede the high volume air flow to the starter; unless of course it is 'high volume' or rated to the flow which they generally are not. However, a properly sized strainer should be in the load line to protect the starter from debris that might pass-over from the tank or lines.

Ideally, you would have two receivers in a cascade arrangement. The first will receive the air from the compressor. The water separator and regulator will be located between the first and second receivers; the second receiver then storing 'dry' air at system pressure. This is one method I have worked with on many ships.

I do not agree with you at all. In fact some times it may be counter-productive. Because, reduction in pressure of saturated air will increase its dryness. Please refer Sp Humidity vs Pressure chart for air saturated with moisture.

i think your splitting hairs with the location of the regulator and trap some relevant considerations are; elevations (think drip legs) and ambient conditions. your drawing is a nice one dimensional sketch, but how much moisture this system is expected to handle and are the pipe sizes large enough to handle it. is the piping pitched in the right direction?

In-line receiver also acts reservoir. It drops the flow pulsations. Besides, the velocity drops down across the receiver. assisting water to get drooped inside the reservoir. Then, of course you need a condensate trap at the bottom of the reservoir to knock-off the condensate.

No way to use the compressed air directly from the compressor to the load equipment. The air must flow through an air receiving drum which used as a surge tank to avoid abrupt variations in loads which can affects on the efficiency of the compressor. Also, using the air receiver tank will damp any pulsation in flow where the output shall become quite smooth flow which shall maintain the soundness of instruments and its operation.

well the above said by all the gentlemen is true, its highly recommended to have your compressor outlet goes to receiver tank,at the bottom of the receiver you need to have the valve that you'll use to drain the condensate and remember considering ambient conditions and the amount of heat/temperature that your air still posseses,it will continue to cool down as it travels from the receiver to the load along your pipelines therefore that the reason why you will need service unit before your load to ensure good qaulity of air to your load.

if the load is being supplied with air that has water contaminants, it will damages your seals of your cylinders and the overall system will be inefficient!

i have not fail i have find ten thousand ways that won't work!

Sounds like your air is hooked up similarly to a hydraulic system with an accumulator or electrical system with a capacitor. When the air is not driving the diesel engine it diverts to the receiver and when you power the diesel the receiver can kick back to reduce pressure loss and add to the flow. I like it.
