Abstract
Methods and systems involving thermal desorption of an oily slurry are provided. In some embodiments, such systems include a desorption vessel including an inner chamber; a heating unit disposed adjacent to the desorption vessel configured to heat a slurry including solids and oil disposed in the inner chamber of the desorption vessel; and a plurality of vapor outlets in fluid communication with the inner chamber of the desorption vessel, wherein each vapor outlet is in fluid communication with a condenser or an eductor for condensing vapors generated by heating the slurry.
Claims20
A system comprising:
- a desorption vessel comprising an inner chamber;
- a heating unit disposed adjacent to the desorption vessel configured to heat a slurry comprising solids and oil disposed in the inner chamber of the desorption vessel;
- and
- a plurality of vapor outlets in fluid communication with the inner chamber of the desorption vessel, wherein each vapor outlet is in fluid communication with a condenser or an eductor for condensing vapors generated by heating the slurry.
A method comprising:
- heating a slurry comprising oil and solids in a desorption vessel to convert at least a portion of the oil in the slurry to oil vapor;
- removing at least a first portion of the oil vapor from the desorption vessel at a first oil vapor outlet;
- and
- removing at least a second portion of the oil vapor from the desorption vessel at a second oil vapor outlet.
A system comprising:
- a desorption vessel comprising an inner chamber;
- a heating unit surrounding the desorption vessel and configured to heat a slurry comprising solids and oil disposed in the inner chamber of the desorption vessel;
- a plurality of vapor outlets in fluid communication with the inner chamber of the desorption vessel;
- and
- a plurality of eductors configured to condense vapors from the plurality of vapor outlets, wherein each vapor outlet is coupled to an eductor.
