rotw Even though there's not much information about exactly what you are trying to do, I guess your approach is just fine. About the software you are looking for there are many, but I saw a review last week telling that for scientific uses the most common one is MATLAB ANN Toolbox. I'll send...

Berenger I believe your question is difficult to answer because dont have the P&ID. Never saw TEG used inside a heat exchanger. The most common is to have a contact vessel where you have a flow of gas in contercurrent with TEG for dehydration. This heat exchanger can be part of TEG regeneration...

If the question is how much CO2 is dissolved in methanol, the answer should be: 1) 0,17 mol of CO2/0,5(0,4999) mol of methanol This would be the answer with no need to complete the division operation The 0,2503 is more like mol% of CO2 in teh liquid solution. believe there's nothing to do...

RHSQ Maybe I am not understanding your quastion, but the Antoine's equation is written for pure components and not mixtures like this one you have. But once you use the UNIFAC to find Gama1, for exemple, you will find the vapour composition by Raouls law P*y1=Gama1*p1*x1 .: (p1 - vapuor...

Considering the dimension of the pipe and the size of the relief valve (must be small comparared to the pipe), the time of the depressurization must be long and it means you have enough time to exchange heat with the surroundings. In short, a slow depressurization is nearly isothermal. The model...

There is a table you can use to facilitate your calculationshttp://files.engineering.com/getfile.aspx?folder=62dc7a70-f878-459b-96e7-bd48b4bb97eb&file=TEST.xls

hgjor I believe it has to do with the kind of emulsifier you have in the oil. This may work for asphaltenic stabilizers. Do you have some of the papers?

The bigger nozzle ID (gas outlet) won't cause trouble for your gas flow. I believe the only problem is to have an overdimensioned material. According to your table you must have a minimum of 7.34 in for the gas outlet ID. Anything much greater than that will only make the construction more...

I believe it will perfectly do. ThankYou

Anyone know where I could find a good material for learning C++ programming? I would rather prefer if it was by linux

IgnGasP I found a good reference for the problem you are trying to solve: http://www.ijee.ie/articles/Vol13-2/ijee924.pdf This is a article about a model for charging and discharging of vessels. They solve for the small vessel problem (your adiabatic case) and for the large vessel (isothermal...

First you should ask for the system caracteristics. Without the information is really not possible to project any system. These kind of systems normally applies a tank where the product will be contained and 2 pumps(one is stand by). We normally use positive displacement pumps (usually when big...

Morten You are no dealing with children... Your last comment was totally unnecessary. If you don't want to help we don't need your help

Zonnegod Is important to understand that the gain of the PID is not always the key to adequate the response of your system. Can make it unstable The best thing is knowing your system behavior and equationate it, but if it is not possible because of the complexity you can infer the behavior by...

You can carry out your simulations with SCILAB. There's a apllication inside called XCOS that works like SIMULINK (from MATLAB) and make it easy to simulate the response for any kind of system. You can download it for free at: http://www.scilab.in/ I actually used to simulate the response of a...
