Simulate part: Staker-Line-Sphere are testing, you can test it using this example.

*******

Estrange bug was fixed. The main data online was changed.

*******

Simulate part: Staker-Tank-Line are testing, you can test it using this example version 6.9

*******

Design part: In part of pipe design was added 3 new targets. Now you can estimate diameter, but also flow, pressure inlet and pressure outlet. You can test these with these examples. If you have more targets tell us, in our forums.

Factor Z was enabled for  density gas calculations.

*******

fixed it -> /we notice this program needs about 10seconds to load./ you can see the progress of loading.

*******

The function of simulation was desenable. This function will activate step by step.

******

I added FAQ page.
I recommend read that before download the program

I notice this program needs about 10seconds to load. I will try to reduce it.

Greetings

New information about, benzene , cyclohexane, ethylene, cumene, phenol, thoose information are not complete, about you can see the preview.

*************

Theory about density of hydrocarbons, list of reaction that will include in petrocad, Main menu of the site was improved.

**************

Guestbook page was improved, now it has two search button, one is for compound and the other is own search our page, the last is experimental program.

********

New guestbook page was created.  you can put your website, or advice here;  but all the posts are checked by automatic program, in order to not have problems, use simple and short english sentences. you could put whatever you want(except inapropiate things), because we wont delete your post. we add get properties to guestbook. 

********

I added a new page. this page was created for ppc (pocket personal computer)
get properties used in order to obtain density, ebullition temperature, vapor pressure, etc
of course,so you can use in your laptop. In addtion, you can see a nice tutorial here

I aaded 3 new examples about Petrocad3d :
Example about design of pump
Example about design of valve
Example about design of pipe

*********

I added a few information about NPSHr : http://petrochemical.gronerth.com/linkus.php?link=35
A look here for other information : http://petrochemical.gronerth.com/design/questions_possible.htm

By the way. I will update Petrocad3D with new function and solving some bugs and i added a little tutorial in this place :

Have a nice day.

Hi

Problems about VDP compute was fixed, and the program was improved, now it is faster and extended to liquid fase. Now you can work in gas or liquid fase and you can see what formule is used by the program.

**********************

Some problem about of units convertions were fixed.

***********************

check out that the  values of vicosity and densiy are all right.

************************

This program is used when you want to estimate the diameter of pipe.

Example

Image you need to move 119204gr/hr of Methane, the pressure in the beginning is 3.98Atm, and the end must be 1.68. The temperature in the beginning is 75F and the end is estimate in 65F. If the length of the pipe is 2mile, what is the diameter?

You can test in this site : http://petrochemical.gronerth.com/linkus.php?link=23

Have a nice day

This program is being tested.

Example:

50 Bencene, 25 Toluene, 25 o-xylene. And your target is 32.5 of 100 mole on the top at the end.

Results

W = 0.675
33.43% of O-XYLENE
28.09% of TOLUENE
38.48% of BENZENE
**** TOP *****
D = 0.325
7.49% of O-XYLENE
18.59% of TOLUENE
73.92% of BENZENE

Hi

This program is finished.

You can test that program, in this site : http://petrochemical.gronerth.com/linkus.php?link=24

RVP is used in Gasoline and Turbo fuel specifications.

Hi friends,

I appreciate very much your visits to my site.

I dont have enought time to maintaing a blog, this is the really reason this blog is external to my site.

In this blog i will talk about my programs in my site.

Please dont sumit any question or comment in this site. If you want to tell me any thing, use muy personal guestbook. You can write whatever you want in my personal guestbook, but not here.

I dont like to modify my page just for one thing, instead it, i will put this thing in this place.
