in my opinion, there are so many different conditions, formers, structures and compositions (say as example hydrate formation at sea, GHSZ) and probably errors differ from case to case, anyway for the mentioned gas well composition I think the values provided by apetri are correct (tested...

there are several papers discussing these applications, comparing different design types, etc. see for example "High Pressure Gas-Liquid Separation: An Experimental Study on Separator Performance of Natural Gas Streams at Elevated Pressures" the authors came to the conclusion that inline...

with hydrates I have used CPA electrolyte which (in Prode Properties) reduces to the CPA PR in the absence of electrolytes giving the advantage of one model for MEG & salts... you may find some numbers here, "http://www.prode.com/en/hydrate.htm" with a different method (manual) you sum up...

20:22 -> 20:31 nine minutes to read the post, think about and give a detailed answer... that' really amazing !

the Mcketta and Wehe chart gives maximum content of vater in vapor phase at specified temperature and pressure, additional water will condense as free water. The reported difference may depend from several reasons 1) gas not saturated with water 2) errors in sampling, measurements etc. 3)...

Morten, I appreciate your efforts to validate the results, with standard models you should be able to replicate (within the tolerance allowed by different databases) the values which I calculated with Prode Properties (see my previous post) results for Tin -30C Pin 4250 Psig Pout 0 Psig...

Morten, you may google for T-S or equivalent diagrams of nitrogen, there is even a specific page in wikipedia with a step by step example of how to evaluate JT effect with a T-S diagram http://en.wikipedia.org/wiki/Joule–Thomson_effect if you wish to simulate the process (solving a H-P flash...

Cylinders are utilized daily in thousands of industries, http://www.lindepremiumproducts.com/internet.lg.lsg.usa/en/images/psa_gaseous_nitrogen892_21857.pdf one can ask directly the supplier, also it seems strange (to me) the idea to run a simulator to calculate JT without keeping in account...

I must agree with xeng, you do not need a simulator to calculate dT for nitrogen but basic knowledge of thermodynamics and a table of enthalpies or a mollier chart (available in most textbooks). In addition you must take in account heat transfer mechanisms, may be you do not have a sufficient...

I agree with Zdas04, you need to select a suitable method and integrate in time domain, by the way, I would guess from your comment about pressure drop correlations that your knowledge in this field is limited, microgravity influences mainly two phases flow, see for example Measurements and...

you already have the answer, so, why ask ? If you need some numbers, sure you'll get numbers :-))

I would definitely NOT use hysys, there are much better alternatives, for some CO2-Methanol VLE see http://jcsp.org.pk/PublishedVersion/6d677561-7384-4903-ae49-9aa6f9e56df3Manuscript%20no%203,%201st%20gally%20proof%20of%209142%20_Hiua%20Daraei_.pdf

since you are posting on a forum for process engineers I presume you mean the advantages solving process operations, for most operations (as flash operations, columns, phase envelope, pipelines etc.) PRODE PROPERTIES 64 bits runs about twice as fast as 32 bits versions on my Excel 2010, also...

I am evaluating the solid fugacity model available in Prode Properties for multiphase equilibria, my field of application would be mixtures of hydrocarbons with CO2, H2S etc. I need to estimate freezing points (or, in general, problematic conditions), which are the main limits (which I should...
