Hi,

Glycol contactor:

The amount of water from the outlet of contactor is given, but i need to know the water content in the inlet. For this the document says that the inlet gas is saturated with water vapor. kindly guide me in finding the inlet water content. Also need to know how glycol injection rate should be calculated.

HIHI

First of all, what is a "GDU"? If you know, let the rest of us also know. Stop using acronyms and abbreviations without defining them.

Secondly, who gave you the amount of water at the contactor outlet and for what reason? What type of glycol are you proposing to use?

If you are trying to design a glycol dehydrator unit, tell us for what reason. Are you a student assigned to do this as homework? If you are a professional, then you would not have been assigned a project you don't have any experience in.

The means to calculate the water content in natural gas is found in the GPSA Engineering DataBook.

Are you planning to INJECT the glycol (as you describe it), or do you plan to recirculate glycol through a glycol contactor?

Await your response.

Art Montemayor,

I Am a Trainee engineer just passed out. I am just doing a assignment.
As u said GDU is nothing but a GLYCOL DEHYDRATION UNIT.

In one of the clients design criteria (bid document) the basis given for dehydration unit is

1.THE INLET GAS IS SATURATED WITH WATER VAPOR.
2.THE AMOUNT OF WATER IN THE OUTLET.
3.PRESSURE & TEMPERATURE.

Thats it.

Ya the GLYCOL needs to be recirculated not injected.
Help me in finding out the water in saturation and also finding the recirculation rate...

Please have the courtesy of addressing my questions and comments regarding your initial post. I can´t help you if you don´t furnish the information I requested.

Be specific and detailed in your reply. I can't read minds and I don't speak your language. Words like "passed out" and "Ya" are unknown English to me. Do you mean "graduated" and "yes"?

If you are a "trainee", then you have never designed or operated a glycol dehydration unit; therefore, you are not qualified to design such a unit. Explain what and why you need this information.

I've already given you the source of the engineering data and instructions on how to calculate the amount of water in saturated natural gas - the GPSA Engineering Databook.
