| 20120103514 | Lateral pipe lining method and lateral pipe lining apparatus - A main pipe is lined by a main pipe lining material comprising a resin pipe made of a thermoplastic resin. A flange of a lateral pipe lining material is formed of a material capable of being welded to the thermoplastic resin of the resin pipe of the main pipe lining material.

The method includes the steps of: (A) mixing at least: (i) produced water, wherein the produced water comprises suspended coal fines; (ii) one or more oil-soluble phosphate esters; and (iii) water-immiscible solvent; wherein the mixing is in proportions to obtain an oil-in-water emulsion; (B) allowing or mechanically causing the oil-in-water emulsion to substantially break into: (i) a first fluid having a continuous phase comprising at least some of the water from the produced water; and (ii) a second fluid having a continuous phase comprising at least some of the water-immiscible solvent; and (C) mechanically separating the first fluid and the second fluid. Optionally, the step of mixing further includes mixing with a crosslinker for the one or more phosphate esters to form a gel for suspending the separated coal fines. | 2012-05-03 |
