  • Patent number: 10260031
    Abstract: This disclosure describes techniques to optimize dewatering process in a production facility. A process separates components in a mixture by using a separation device and a dewatering device. The process receives the mixture of liquids and solids, and separates out suspended solids from the mixture of liquids and solids by using the separation device, wherein a liquid with insoluble solids stream is created. The process dewaters the liquid with insoluble solids stream by using the dewatering device to produce a liquid with small particles stream and insoluble solids having particle sizes that are greater than about 20 microns to about 1000 microns.

In difficult liquids or highly reactive treatment chemicals even so-called “inert” tracers end up reacting and their fluorescence changes. As a result they are inconsistent and cannot be used to measure the amount of treatment chemical present. But by encapsulating the tracer dyes, even non inert tracer dyes become inert and they can reliably be used to measure the amount of treatment chemical present even if highly reactive or in a difficult liquid.

    Abstract: A method of flocculating coal fines from produced water that 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.

  • Patent number: 8585992
    Abstract: The invention is directed towards methods and compositions for treating slurry to better dewater alumina trihydrate precipitated from the Bayer process. The method comprises using a product comprising the combination of at least two surfactants together with an optional coupling agent to treat the alkaline slurry with certain amount of alumina trihydrate present. Synergistic effects between binary combinations of nonionic and anionic surfactants result in more efficient dewatering aids for alumina trihydrate slurry when combinations of such surfactants are applied. A coupling agent may be used in formulations to reduce viscosity of such surfactant combinations, allowing the practical application of such products.

  • Publication number: 20130153510
    Abstract: The invention relates to a method and system for treating an aqueous stream having a first flow rate and containing solid matter exhibiting first settling properties, the method comprising adding a modifying agent to the aqueous stream at an addition rate sufficient to change the first settling properties of the aqueous stream to obtain a modified aqueous stream having solid matter exhibiting second settling properties different from the first settling properties; taking batchwise samples of the modified aqueous stream to a settling vessel having a volume; determining a settling property of the solid matter of the samples in the settling vessel; and conducting the modified aqueous stream to a separation unit in which solid matter is separated from the modified aqueous stream. The invention provides a convenient way of monitoring and/or controlling aqueous streams conducted for example to purification processes.

  • Publication number: 20130134103
    Abstract: Disclosed herein are systems for removing particulate matter from a fluid, comprising a particle functionalized by attachment of at least one activating group or amine functional group, wherein the modified particle complexes with the particulate matter within the fluid to form a removable complex therein. The particulate matter has preferably been contacted, complexed or reacted with a tethering agent. The system is particularly advantageous to removing particulate matter from a tailing solution.

  • Publication number: 20130112627
    Abstract: The invention provides methods and compositions for improving the rheology of red mud removed from Bayer Process liquor. The method includes adding a flocculant and a cross-linked polysaccharide to the liquor. This combination separates the red mud from the liquor but also prevents the red mud from becoming too thick. By preventing excessive thickness, the method allows for the formation of extremely dense amounts of red mud even in primary settlers because the dense red mud can still flow. As a result a user can simultaneously enjoy both easy handling of red mud and also high recovery rates of valuable alumina and caustic from the red mud.
