Hi all
I am having a big debate in my organization in calculating the volume correction with pressure and temperature correction in a diaphragm type gas flow meter. According the manufacture the below is the formula for corrected volume
Vb = V x Pabs/Pbase x (273.5 + Tb)/(273.5 + T)
where
Vb =...
Dear All
I am looking to procure a GC for hydrocarbons from C1 to C8. Suggest a suitable and best ones.

@DieterVk: Hope you are talking about Hydrocarbons i.e. Propane, Propane:Butane mix etc. This said because of the physical property of LPG. As the density of LPG Vapour is heavier than air, it will accumulate in the lower areas, hence the sensor must be facing downwards. Also it must be kept at...
@3DDave: Thanks for your information. Can I try by adjusting the linkage, further if it is not working I can decide accordingly.

Hi All
The Air suspension of trailer (LPG Tanker), is hitting and there is heavy abrasion of tyre and mud flap, this sometimes results in tyre blast. Can this be sorted out by adjusting load sensing valve linkage or should I do any other procedures. I need your suggestion guys. Photos of the...
Hi All
Can I use a quick release coupling in a 3/4th LPG hose, I am checking with Swagelok, I want to make sure where it can be used or someone of you tried, if so, can you share the specs and manufacturer?

@btrueblood: I have also thought on this point. The sample was taken while unloading a road tanker from refinery. Probably, the heavy-ends do not get trapped because of flow velocity. Talking about strainer, I didn't find any contaminants while cleaning a strainer. The installation is one year...
Now another interesting issue, is a fork lift which runs in LPG fuel, got its vaporizer clogged. Photo of the damaged part attached.

@rossABQ: We have one in the vaporizer outlet, not before each regulator
@3DDave: We have did that too, and the reports are clean. I am thinking to send the sediment for separate analysis, maybe FT-IR, distillation. If you have any idea, for specific parameters to look for during analysis...
@Chicopee: Its not soot, instead its a sticky semi solid kind of stuff, black in colour and with a pungent smell.

Thanks, I will work on it.
On the other hand, being a mechanical engineer, I want to read about each hydrocarbon (methane... pentane, hexane etc.) their properties, which will be a suggested book.

Hi Everyone
I came across an issue in which heavy-ends/Oil sediments were found in gas train of an LPG fired burner, used in a drying oven of a Powder coating process. This results in frequent tripping of burner and affects product quality. System details as below

We performed a Hydrostatic test at 30bar for 30mins, there was no leak and pump is installed and running successfully. Thanks everyone.

@Artisi: Our people are qualified and have experience in assembling pump. But there is a person who is insisting to perform a test by running the pump at 30bar with Water. I need a standard to prove that such test is incorrect.

@Artisi: to ensure the right assembly and to ensure the sealing.
@LittleInch: Manual says Hydrostatic test, but I want to know is the a standard available in API, NFPA, ADR etc.

Hi Everyone
We opened a multi stage centrifugal pump and replaced the mechanical seal. Before installing the pump in the process, what kind of tests to be performed and is there any standard specifying about the test, parameters etc.,?

hi
You have to configure the adhesive layer using COHESIVE ELEMENT, this is possible with APDL and Workbench(R15 onwards). you have to give the material properties for the cohesive layer according to the properties of the bonding material. Use ANSYS help it will help you better. If you need...
@metenger: wear is in impeller mounting portion and discharge end casing area. Shaft material is AISI420
@MJCronin: Belzona representative has suggested 1111 super metal.
