Hi, In the link attached propane bottle is mentioned as a backup ignition source. https://www.icheme.org/media/14673/flare-system-design-for-oil-and-gas-installations-chris-park.pdf notes: backup system must be tested regularly and recorded Be in touch with your firefighting brigade, authorities...

Hi, Google : trommel screen Good luck Pierre

Hi, Have you ever considered to wrap your underground pipe? https://www.densona.com/application/buried-onshore-coatings/ My 2 cents Pierre

another reference Rashig in Germany. They have a nice software with good data base, Winsorp.

Hi, Probably good to read: HTTPs://greywateraction.org/greywater-reuse/ Pierre

Thanks George.

George, My calculation using PR EOS is 1.42 for Z at 26.66C and 656 bars Abs. Regarding dissolved N2/m3 of aqueous solution, I got 11. 1 to 11.8 kg/m3 Attached Henry's coefficients with references. Pierre

Probably good to read! https://www.fda.gov/inspections-compliance-enforcement-and-criminal-investigations/inspection-guides/high-purity-water-system-793 Why don't you consider a package (RO+EDI) and ask a third party mastering this process to design, to build and to commission the whole unit...

Hi, Check with those guys: https://www.hermetic-pumpen.com/en Looks not great. Key on hot oil minimize the number of flanges to mitigate the risk of fire (leaks). I don't buy the story about strainers at the pump suction for the reason above and other risks associated (burn). Very dangerous...

Hi, Most Engineering companies have developed their own standards based on velocity and nature of the product flowing in the pipes. Sometimes the results are expressed in head loss (m of Ft) per 100 (m or ft) of pipe. The % you mentioned will be an indication not an engineering practice. Pierre

LI , "The practical issue becomes how do you start and stop this system", that's the main point not addressed in the replies above. Not considered by the OP. Pierre

I think the 25 m3 tank is a buffer tank, necessary to transfer the material from the tanker, to avoid additional logistic costs. What you call a booster pump is a transfer pump. To me you need a capacity to collect the liquid from the filter prior to the pump. This will mitigate the risk of...

Got it, Pierre

Your downhill pipe should be self-vented, check Froud number. Apply Bernoulli to the top of the system to ensure fluid will be transferred. Continuity applies from the top to the point 2, head loss should be compensated with the static head. For your consideration...
