Sedimentation (Fuel Oil)

[jagfrediani]

Hello everybody:

I'm making a project in a cement factory and i would like you to help me find some information...

We have a rotary kiln that burns about 53gal/min of Fuel Oil N6, it has a relative density of 0,983 (@15,6ºC) and a kinematic viscosity of 416 cSt (@50ºC). All the Fuel is stored in two tanks of 5500 m3... Near to those tanks we have some heater exchangers to get a lower viscosity and then pump the Fuel Oil to the kiln, THE PROBLEM IS that lately we have been receiving the fuel with a high degree of contamination (silica and other kind of particles) and our present filter system can't prevent clogging of heat exchangers because of the dirt.

The very first idea is to work on the filter systems, but also i have to evaluate the possibility of making a sedimentation tank, i want to know how much time the Fuel has to be steady so the particles and even the water get to the bottom of the tank...

I've found a lot of papers of sedimentation but working with water, i need information about sedimentation in Heavy Fuel Oil... How and where can i get that information?

Any comment, any suggestion is welcome... thanks in advance
