Method for transportation and agitation of refinery solids waste
A method of transporting solid refinery waste includes loading solid refinery waste into a mobile tank having at least one sloped floor wall and a plurality of compartments separated by at least one buffer. The method may also include maintaining a head space between a top level of the solid refinery waste and a top wall of the mobile tank. The method may also include delivering the mobile tank to a burning facility that maintains a reserve of diluent and that is equipped with an agitator configured for lowering into the mobile tank through a manhole opening, to thereby permit the diluent to be conveyed into the headspace and mixed with the solid refinery waste, thereby enabling a resulting mixture to be off-loaded for burning at the burning facility.
1. A method of transporting solid refinery waste, the method comprising:
loading solid refinery waste into a mobile tank having at least one sloped floor wall and a plurality of compartments separated by at least one buffer;
maintaining a head space between a top level of the solid refinery waste and a top wall of the mobile tank;
transporting the mobile tank loaded with the solid refinery waste such that during transporting the at least one buffer impedes migration of solid refinery waste between the plurality of compartments; and
delivering the mobile tank to a burning facility that maintains a reserve of diluent and that is equipped with an agitator configured for lowering into the mobile tank through a manhole opening, to thereby permit the diluent to be conveyed into the headspace and mixed with the solid refinery waste, thereby enabling a resulting mixture to be off-loaded for burning at the burning facility;
wherein upon delivering the mobile tank to the burning facility, the agitator is temporarily fastened to at least one connector on an outside of the mobile tank, the at least one connector being attached to an external side of an upper side of the mobile tank, and
wherein the at least one connector is configured for connection to the agitator in a manner permitting the agitator to be controllably lowered from an upper position toward a floor of the mobile tank while the agitator is agitating.
2. The method of claim 1 , wherein upon delivering the mobile tank to the burning facility, an assembly associated with the agitator is sealed to the manhole opening to substantially prevent hazardous gas from escaping from the mobile tank to an outside environment of the mobile tank during mixing.
3. The method of claim 1 , wherein loading solid refinery waste into the mobile tank includes arranging an output end of a conveyor above the manhole opening in the mobile tank, and conveying shredded constituents of sold refinery waste into the mobile tank.
4. The method of claim 1 , wherein the burning facility is further equipped with a pressure control system for maintaining a pressure inside the mobile tank lower than a pressure outside the mobile tank.
5. The method of claim 4 , wherein the pressure control system is further configured to evacuate gas from the mobile tank when the diluent is added to the mobile tank.
6. A method of transporting solid refinery waste, the method comprising:
loading solid refinery waste into a mobile tank having at least one sloped floor wall and a plurality of compartments separated by at least one buffer;
maintaining a head space between a top level of the solid refinery waste and a top wall of the mobile tank;
transporting the mobile tank loaded with the solid refinery waste such that during transporting the at least one buffer impedes migration of solid refinery waste between the plurality of compartments; and
delivering the mobile tank to a burning facility that maintains a reserve of diluent and that is equipped with an agitator configured for lowering into the mobile tank through a manhole opening, to thereby permit the diluent to be conveyed into the headspace and mixed with the solid refinery waste, thereby enabling a resulting mixture to be off-loaded for burning at the burning facility; and
wherein loading solid refinery waste into the mobile tank includes arranging an output end of a conveyor above the manhole opening in the mobile tank, and conveying shredded constituents of solid refinery waste into the mobile tank.
