Abstract
Methods and apparatus for treatment of hydrocarbon streams containing cuttings are described herein. The cuttings are treated in a treatment stage comprising a fluidized bed treater to reduce oil content of the cuttings to less than 1% by weight. The cuttings are provided to the treatment stage from a preparation stage that lowers oil content of the cuttings to a suitable range for the treatment stage and sizes the cuttings to a suitable dimension range for the treatment stage.
Claims15
A method, comprising:
- reducing oil content of solids in a dryer;
- reducing a size of a portion of the solids in a sizer;
- and
- treating the solids in a fluidized bed treater in a treatment stage to reduce oil content of the solids to less than 1% by weight.
1 more element
A method, comprising:
- reducing oil content of solids in a dryer;
- using a separator to separate solids from oil recovered in the dryer;
- reducing a size of a portion of the solids in a sizer;
- routing solids recovered in the separator to the sizer;
- and
- routing solids from the sizer to a fluidized bed treater in a treatment stage to reduce oil content of the solids obtained from the sizer to less than 1% by weight.
3 more elements
A method, comprising:
- reducing oil content of solids in a dryer to a target;
- using a separator to separate solids from oil recovered in the dryer;
- reducing a size of a portion of the solids in a sizer;
- routing solids recovered in the separator to the sizer;
- and
- routing solids from the sizer to a fluidized bed treater in a treatment stage to reduce oil content of the solids obtained from the sizer to less than 1% by weight, wherein the target is matched to a capacity of the fluidized bed treater.
