I need help with dehy operations

could you tell me some parameters for my dehy?

That's a pretty vague question. How can we tell you what the parameters on your unit should be with no information?

It would help to post some specifics on your unit and what you are trying to achieve.

It sounds like dryness is the objective. Is this for natural gas, carbon dioxide? If there is an aluminum exchanger downstream there may be critical maximum outlet temperatures. Is the dehy unit upstream of a cryogenic unit?

The block valves need to be tight shutoff and perhaps higher temperature than typical ball valves. Orbit valves are commonly used in some systems and are only tight shutoff in one direction.

If he's posted it in the Petroleum production forum he's likely talking about an electrostation precipitator for removing water/salt from crude oil.

I guessed at natural gas. Dew point depression of natural gas is a production issue. Various orgainzations might consider any gas processing a production issue. The dew point of gas must be low for cryogenic turbo-expander plants. I think that this is exagerated if the gas contains much CO2.

You went for gas, I went for oil, we must have it pretty well bracketed don't you think? ;-)

Furthermore - it seems like you are speaking without beeing heard - wapiabi has not logged on since his original post :-(
