RE: tank cleaning

At the top of the page ther eis a search bar.

Type "tank cleaning" into this and click on the results - this has been discussed many times.

Please define "heavy cycle oil" - do mean asphalt? please be a bit more precise
Why would you need to cut it?

Please also provide some more background information otherwise all you will get is general responses, so things like:
Product ( be as precise as possible)

What is size of tank?
Is there a clean out door or specificed area to cut
Is the tank lined?
Are the contents dangerous to health or could create an explosive atmosphere?
Where in the world are you?

RE: tank cleaning

(OP)
currently used to store fcc column bottom product having dia 24.4m height 17.1m total gross capacity 7990m3 40-50% sludge & catalyst fine particles.material is highly viscous and heavy.
tank is fixed cone roof and inverted cone bottom.Tank claddes with 40mm insulation externally.

RE: tank cleaning

Is this a one-time issue or is it recurring?

Sounds like a mixer of appropriate design might be the key to avoiding this settled condition in the first place. The list of mixer manufacturers who can manage extremely high viscosity materials is quite short. This is a specialized mixing application and a lab test is probably in order.
