Abstract
A method of recycling or destroying the components of viscous oil well drilling mud and saltwater which includes reducing the mud to an aqueous slurry; separating and collecting the useable hydrocarbons from the slurry by evaporation or chemical action; injecting deleterious substances including saltwater into an environmentally approved injection well; and or forming fertilizer pellets from remaining dehydrated solids.
Claims1
A method of recycling brine separated from oil well drilling mud comprising the steps of:
- a) centrifuge separating brine from drilling mud solids;
- b) aerating the brine by progressively trickling it down a series of descending steps for oxidizing iron;
- c) collecting the brine in a sedimentation tank;
- d) converting organic matter in the brine to carbon dioxide gas by spraying the brine on a trickle filter containing microbial solid matter growth;
- e) transferring the brine to a flocculator;
- and,
- f) clarifying the brine by adding magnesium hydroxide thereto.
