Bunker C viscosity 1

[BasellBoy]

Hi everybody!

I'm brand new on this site and i need your help on this. I have a bunker C tank who contain 20 000 gallons of bunker oil (Type 6C3). I need to know if the viscosity of the bunker change in the time. My oil have about 23 years and i want to pump it. Do you have an idea about this?

I wait for your response!

Thanks all!

to pump it regardless of age you'll need to heat it. minimum temperature is 150-200 F.

with time the volatiles come off and the heavies remain so it can even be more viscous.

it is similar to No. 6 fuel oil. take a gravity sample that will tell you a lot.

Tks for your help, i appreciate!

hacksaw is right. The material standing for so long may have solidified, oxidized, who knows what. Take a sample to the lab and see whether heating is enough, or may be you'll be obliged to dilute it with a lighter hydrocarbon to make it fluid and pumpable.

Tks 25362!

The problem are that H2S can be in high level of PPM. If i heat this, i think that i will be obligated to furnish air adduction mask to the workers who will enter in the tank when the bunker level will be approx. 3-4 inches (to mix with oil no.2). That the big point in my project. In fact, if nobody entering in the tank, no problem will occure, but in my case, i have to send workers into a high risk area i think. I have no risk to take with that. So, i will continue to talk to the compagny who want to pump my bunker to try to have the safer way to do the job.

I tank you all for your help!
