water in Heavy fuel oil #6
water in Heavy fuel oil #6
(OP)
Hello everyone!!! any of you know if it's possible to distillate Heavy fuel oil 6 in order to determine the amount of water in HFO 6 plus any suggestions on how to reduce the amount of condensated water in the bunker?
Thank you
Thank you

The two may become entrained but have you not ever heard that "oil and water don't mix". Oil floats on the water, so allowing some time for settling and then draining the tank (from the bottom) will eliminate most all of the water.
If you cook anything at 100C, the water vaporizes. Capture the vapors, condense it and measure the water.
Remove all condensates before reaching 100C.

Product quality control specifications (you're the ASTM expert) require your oil to meet limits on water content and other compounds. If you mix crap with the water, you have not removed the water ... plus now you have crap. What we going to do? Mix WD-40, or alcohol with the water so the water will go through fuel injectors and get vaporized with the pre-ignited combustion process you've started and then leave the mud it carries with it to plug the injectors?
Remind me which country you are, so I won't buy any fuel there ... or fly your national airline.

dief sanc,
yu seem to know some things and not others. If you look up ASTM D96, you should also find reference to ASTM E123 - Standard specification for apparatus for determination of water by distillation - You can buy this for between $22 to 44 - just search for a download online or find someone in your company who has it.
As regards your other point, then to reduce condensed water you need to control what gas is entering the tank when you empty it. This normally means some sort of inert gas (nitrogen) or dried air. Depending on your tanks and flowrates in and out this could be quite simple or a major issue. Most tanks which are designed as "atmospheric" will stand a small positive pressure of a few mbar, but normally very small negative pressures.
given that no 6 HFO is something resembling tar and needs a high degree of heat to move it anywhere - what is yours stored / moved at? - your condensed water might actually be coming from the fuel itself and then just condensing on the slightly cooler walls or roof of the tank if you're storing it at 50C+.
You give us so little detail it is impossible to be any more specific.
More details = better answers

Here are some suggestions
Step 1
Pass the fuel oil through a fuel filter coalescer-that should remove most of the free water. If the fuel oil has particulate matter in it, you'll need a particulates filter upstream of this fuel filter coalescer. Fuel filter coalescers are readily available off the shelf from many vendors.
Step 2
You could try one of these non regenerable drying agents in a packed bed if you need to go even lower on water content:
a) Activated alumina - BASF Sorbead
b) Anhydrous calcium chloride
OR if you need a regenerable process ( which is going to involve a lot more equipment and capital ) -
Use mono ethylene glycol in an countercurrrent LLE process with a packed bed
If you have a source of dry gas, try countercurrent gas stripping in a packed bed - we can increase the water vapor holding capacity of the dry gas by heating it up - obviously stay below HFO flash point
Hope this helps

" a) Activated alumina - BASF Sorbead"
Should be corrected to
"Activated alumina OR BASF Sorbead"
For lab scale samples, you've got a centrifuge.
