    Scrubber Sizing Paradox

    So I got another problem that I could use some advice on. It has come time to create a datasheet on a conventional inlet scrubber for use in a typically sweet and dry compressor station (Horizontal with cyclone tubes) and I have to input conditions (density viscosity) for the liquids even though...

    Preferential Flow in Aerial Cooler Configuration

    Thanks for your help unfortunatly it looks like I cannot ignore the pressure drop in the header. At least if I have to do it the hard way next time it should be easier.

    HYSYS works fine for cyrogenic air seperation, we use it all the time. PROII works well also it is just not as common in industry

    Preferential Flow in Aerial Cooler Configuration

    I agree with your post, just 1 point of clarification. If pressure drop is like voltage and flow is like current is "resistance" the same variable as described in Crane Flow of Fluids Technical Paper No. 410 (HL=K*v^2/2g

    Preferential Flow in Aerial Cooler Configuration

    Ok I have never been asked this question before so I need some help. Currently I have 8 aerial coolers in a first in last out configuration (also called "U" configuration I believe) and people i.e my boss is concerned that the first cooler will have more flow due to its smaller pressure drop...

    Non Commercial Approach to HYSYS

    While I do not subscribe too or condone the illegal trafficking of pirated software www.emule-project.net provides a file-sharing program that has access to many such programs. I fear this is the only manner in which you may get to use these programs besides signing up for a course at U of T

    HYSYS Enthalpy Values

    My faith in HYSYS has not faltered. I just get asked alot of questions about its validtiy (I work with alot of old guys that dont trust "That new fangled technology") and I find that I must provide the burden of proof for every new application we use it in. Let this be a lesson to those who...

    HYSYS Enthalpy Values

    So for comparitive purposes between sets of T and P as long as you use the same source (HYSYS or API) you should be good? I guess I find the absoulte values easier to understand cause I can see and reproduce the calculations that lead to them. As for HYSYS I just can't see any calculations.

    HYSYS Enthalpy Values

    I am curious as to why the values for enthalpy in HYSYS (Peng-Robinson with Lee Kesler Enthalpy Correction EOS) are negitive for typical natural gas. Does this mean that HYSYS compares the enthalpy to a refernce value because when I look up the enthalpy value in the API databook the value is...

    Entropy

    Sorry about the wrong title on the thread

    Entropy

    In HYSYS using Peng-Robinson EOS the mass enthalpy values are all negative, does this mean that HYSYS is comparing the enthalpy at you T and P to that of some refernce state? or is it the enthalpy of formation?

    Typical Diesel Info

    Wow those are alot smaller then I would have thought.

    Typical Diesel Info

    I need to know a typical reid vapour pressure for diesel, I fear that such a number doesnt exist from a quick literature search

    Dense Phase Experince

    I was wondering if any one has experince in designing pipeline equipment for dense phase natural gas. Our gas is 18 MPa and -2 C. I am curious to see the effects this phase has had on their equipment ( pressure drops, psv sizings and such) Dawe.Matthew@colteng.ca
