1. Inlet temperatures not beneficial for S&T operation here.
Benefits over line heater are fuel gas savings.
2. I assume worst case heat input is based on 20C Inlet Gas at 190 Bar to get 11MW. Inlet gas at 30C & 190 Bar requires 16 MM (54 MMBtu/Hr). Also above 80 Bar gas is in...
Dear All,
Virtual Material have been developing a new process simulator called VMGsim for a while, which is heavily based on the Carl Yaws handbook. It's an easy to use process simulator and fees are reasonable. I've used the simulator for the past four months and have compared the simulation...

The authors do calculate the droplet size and compare it against known publications instead of measuring actual droplet size and efficiency.

Check out Tornado Technologies as an arrestor vendor as they use aluminum ceramic beads for flame cell material, which are resitant to oxidation and corrosion. You will need to contact them the about the use of Hastelloy C or other alloys for construction of the body and flame cell...

Art, thanks for the article references as I have been looking for some time to get some more clarity on this grey topic.

Sorry for the late response, but any response is better than no response. To answer your question: Yes there is and there are several ways to achieve this.
1) See Excel Help "Move and scroll in End mode". Help "Navigation Keys", shows Excel uses the CTRL key instead of the END key...

You can cut down the 4 clicks to 1 click, if you use the keyboard shortcut "CTRL + 1", which brings up the "Format Cells" box. You may have to select the "Font" tab, which is 2 clicks, but you only have to do this once, if you repeat this often.
This shortcut is a keeper [bigsmile]...
Hi ColourfulFigsnDiags
You can actually do this with zero programming by using the Excel's "Condition formatting".
Condition1 = Dropdown box = Abs/Rel Address
Cell Value Is = Not Equal to = $A1
Now select desired format option to change cell Font, Border or Pattern.
However this is not...
Kukuran,
One way you really will convince management that they have problem, when you provide them with hard numbers. Express in $$$$ in lost fuel gas cost on an annual basis (work with large $$$) to generate the steam lost thru the relief valves.
To do this estimate how much each PSV reliefs...
Thanks dsi, this works like a charm. I was looking for ways the disable the Click EVENT, but this trick works very nicely.
Also, the FOR loop works nice as I was stumped by that fact that you need to access check boxes indirectly as Control property. This does not seem intuitive to me.
You...
I've developed a VB macro display a form to quickly hide and unhide columns in a large sheet. The value of the check box is toggled to TRUE or FALSE for each column. A FOR loop then shows or hides each column in the sheet.
The code for Hide/Unhiding a single column works fine,
' Hide/Unhide a...

A word of caution here using Hysys and the hydrate prediction model. Your dewpoint temperature of -60°F is not in the range of the model as the temperature is far below the freezing point. On a previous project with high 22% H2S content at 1,000 Psig and 95°F the hydrate model found two...
Hi, JoeNava
Since your are in an area with remote area,
you may want to consider a silica gel adsorption process using Sorbead to remove the excess C5+.
It's an outdated process, but with no large utilities in the area it may be the way to go. A HC dewpoint of -10°C is achievable depending on...
Mitch,
Treat the file as a standalone data file and read the file using the VB "OPEN" statement as a text, binary or perhaps random file, depending on your file format. From this point onward you can do whatever want as you read the file one line or record at a time.
The following...
Here is an alternate solution that may work for you.
The workaround is in the method of copying not by reformating the rows around the cells.
1. Insert one or more rows between each formula and
format cells as required.
2. Enable Datafilter and select "Non Blanks" cells
(This...
Dear Scorcher,
I recommend you contact some of the mistex vendors like ACS, Koch/Glitsch or Nutter to see if a Vane pack (Dixxon plates) is effective in reducing the amount of entrained liquid particles. A knitted demister in this service has a better removal efficiency, but clogs up easier...
A program called "SOLIDS" created by the DB Robinson group of companies does exactly what you are looking for when fluid compositions are known. The program can predict wax amount and WAT for various conditions and back by research done by DB Robinson.

Neyde,
I highly recommend you do an "ADVANCED" search on the ENG-TIPS forums using keywords like "Oversized relief valves PSV dynamic flare headers" and you will find a lot of excellent discussions on this topic that probably answer 85% of your question. ;-)
Tarkjell, one of our clients is doing exactly what you describe and have done this on a number of projects, but only on piping, not on vessels as far as I know. Reference is made to the same section of ASME B31.3 code
They do monitor and record an overpressure event to proof to the local AI or...
