Hello Members,

We are an engineering/construction team that wants to design and construct a new flat storage, loading and reclaiming system of pet coke escaping from the process at the petroleum refinery.

Here is what we know about the product:

1)Specific gravity of 0.5 (32 lbs/ft3).

2)Maximum temperature: 150ºF.

3)Storage of 40,000 to 45,000 metric tons in a flat storage.

4)Conveying product to feed the shed and reclaiming conveyor to reclaim from the shed to the ships.

5)Particles size (less than 4").

Here are the questions and the concerns we have:

1)Is newly produced pet coke has the tendency of self igniting?

2)Can the flat storage be left open considering the location of the plant around parallel 45 north of Boston USA?

3)Is the pet coke susceptible to segregate? Do we have to be concerned about the stock piling process and reclaiming process?

4)Is pet coke a free flowing material?

5)Do we have to spray? (Add water to the stock pile).

6)Do we have to monitor continuously the temperature of pet coke in the storage pile?

Any imput will be very apreciated.

Regards,

Gruia Grigore, eng.
