The reason I'm exploring the possibilities is that the plants have limited footprint to support aboveground storage. Remote plant location limits pre-fab'd bullet size such that at least 10-15 will be required. This also creates the potential for major accident hazard compared with mounded...
I need to run an LPG pipeline 6 km from a gas plant to a pumping station. The elevation drops continuously by 100m with slopes of 1 to 2.5%.
I also need 2500 m3 of LPG storage.
The intent would be that rather than installing an 8" pipeline solely for transportation, I would install 2x 20"...
No allergy to the help system, just a general lack of VB programming knowledge. I do dislike re-inventing the wheel.
IRstuff has previously provided the VBA code, and I am capable of modifying it for a different executable.
However, having the original excel file would make interpreting...
Hi,
I want to interface Excel with an MSDOS executable to export an input file, initiate the executable calculation, and import the results back to excel.
This was previously discussed in the attached thread.
Can anyone share a working macro or VB code?
Thanks
Smile1,
I heard about this at a petroluem show and my first and probably correct assumption is "magic" and "babble-babble of testimonial".
The vendor claims to have installations with different beverage companies in their bottling lines (Pepsi). Also installations in...
Hi,
Have any of you had any experiences good or bad with Chesterton's Vrtx water treatment system? Particularly in a chemical/petroleum processing environment? The system makes a number of claims and I would like to hear some user feedback.
Thanks...
Butelja,
Do you have any experience retrofitting large tanks for blanketing? I'm not sure how easy (read $$$$) this would be as the atmospheric vents are fairly large.
Sorry for not keeping up to date on this....
The tank is used for surge storage of liquid sulphur.
A deluge system is in place for fire prevention.
If a fire occurs the deluge system will dump water into the tank creating steam. The concern is that the roof vents are inadequately sized to...
One other thought.... the union is a straight thread, the LPT is a tapered thread. Number of threads holding axial force is dependant on how deep it is threaded in. Depending on how big your pipe wrench is, you can also overtighten and yield the thread.
I'm not an expert, but there are a few differences between LPT and a union.
1) The union uses a elastomer seal and it's thread does not see process fluids. An LPT seals on it's threads and is susceptible to root corrosion. I've heard of bull plugs with v-threads being launched under pressure...
Yes, I had considered mechanical floats. In fact we use them on other tanks in the farm (Methanol).
I was hoping to avoid any modifications to the tank and the fluid, DMDS (Di-Methyl Di-Sulfide) and Merox (waste stream containing DMDS) are not user friendly and I did not want to put another...
Can anyone direct me to a code or method which defines the sizing requirements for large storage tank vents for an explosion case?
I am being asked to confirm if the atmospheric vents on a large storage tank would allow venting or if the tank would fail catastrophically.
Does anyone know of a battery powered remote level indicator that could be mounted on a tank?
Currently the operators climb the tank and measure level with a dipstick. This is a small remote tank farm with no power source. The instrument could be mounted at the tank outlet nozzle and should...
Be wary of activated carbon scrubbers.... industry experience has shown that the heat of reaction in the carbon scrubber with H2S can reach the ignition point. You need to take the heat away to maintain thermal equilibrium. A continuous flow may achieve this.
If the flow stops, the H2S will...
I have a overhead runway crane which runs on an I-beam the length of the building. It uses a 5 ton hand operated chain fall to lift electric motors out for service.
The I - beam was never given an official rating. It was flagged during our crane inspections.
Can anyone tell me where I could...
