SYSTEMS AND METHODS TO REMOVE HYDROCARBON OILS FROM CONTAMINATED DRILL CUTTINGS

摘要

A system for treating drill cuttings may include a first stage that receives the drill cuttings and generates a first drill cuttings slurry and a second stage that receives the first drill cuttings slurry and generates solids. The first stage may include a mixer receiving at least one additive from at least one treatment fluid supply. The mixer mixes the at least one additive with the drill cuttings to form a drill cuttings mixture and reduces the drill cuttings to a predetermined size. The first stage also includes a separator receiving the drill cutting mixture. The separator separates liquids from solids in the drill cuttings mixture to form the first drill cuttings slurry. The second stage may include a mixer that mixes a cleaning fluid from a second treatment fluid supply with the drill cuttings to form a second drill cuttings mixture. The second stage may also include a separator receiving the second drill cutting mixture. The separator separates liquids from solids in the drill cuttings mixture to form the solids stream and the liquids stream.
