Patent
AMCOL International | Date: 2016-04-22

An apparatus and method for heating produced fluid from a well, the heating apparatus comprising a produced fluid pathway; a heat generation system comprising a diesel engine, a heated hydraulic fluid pathway, and an engine coolant pathway; and a heat transfer system disposed between the produced fluid pathway and the heat generation system to transfer thermal energy from the heat generation system to a produced fluid contained within the produced fluid pathway.


Patent
AMCOL International | Date: 2015-09-23

A sub-aqueous capping material comprising a plurality of compacted particles of a reactive solid material having a dispersion aid homogeneously blended therein, the compacted particles having a specific gravity greater than 1.0, a particle size in the range of about 1/16 inch to about 1 inch, and having a time for disintegration, once in contact with water, of 5 hours or less.


Patent
AMCOL International | Date: 2015-05-13

Herein is disclosed a flue gas scrubbing composition, a method of using the flue gas scrubbing composition, and a method of entombing mercury collected with the flue gas scrubbing composition. The flue gas scrubbing composition includes an admixture of a mercury sorbent material that comprises a clay, copper, and sulfur; and lime that comprises calcium oxide and/or calcium hydroxide. The method of collecting mercury from a flue gas includes injecting the flue gas scrubbing composition into a flue duct comprising the flue gas; reacting the mercury sorbent material with mercury in the flue gas to form a mercury-sorbed material and thereby reducing the concentration of mercury in the flue gas; reacting the lime with SO_(2), SO_(3), and/or HCl in the flue gas to form a calcium sulfate and/or a calcium chloride; and collecting a mixture that includes the mercury-sorbed material. The method of entombing mercury includes mixing the collected mixture with water to form a freshly mixed concrete; and casting the freshly mixed concrete into a form.

A hydraulic barrier composition can include granules of a water-swellable clay and a water-solvatable polymer. Upon contact with a leachate at least portion of the polymer is solvated by the leachate and becomes entrapped in at least one of clay pores, at clay platelet edges, and between adjacent platelets.

A composition capable of increased impermeability against the passage of ionic liquids therethrough can include a clay mixed with an anionic and cationic polymer. Such compositions can be provided in geosynthetic liners to provide a hydraulic barrier in aggressive leachate environments.


Patent
AMCOL International | Date: 2015-05-15

Described herein, in a preferred embodiment, is a leonardite-based polyurethane resin binder that may be used, among other applications, as a binder in combination with foundry aggregate, e.g., sand, for molding or casting metal parts. The binders described herein comprise a humic substance, preferably leonardite, first mixed with a foundry aggregate and then the humic-aggregate mixture is combined with a polymerizable polyol, an isocyanate, and a polymerization catalyst to make a polyurethane resin binder in situ in a foundry aggregate, such as sand. The lignite is added as a solid to the foundry aggregate, and improves the binder performance of the lignite-containing part of the binder components.


Patent
AMCOL International | Date: 2014-06-20

Geocomposite articles that can provide a barrier against high conductivity water e.g., ocean water, are described and their method of manufacture, for waterproofing surfaces that contact high conductivity water. The geocomposite article mat includes a woven or non-woven geotextile sheet or mat containing a powdered or granular partially cross-linked acrylamide/acrylate/acrylic acid copolymer across its entire major surface(s). The powdered or granular copolymer has an unexpectedly high free-swell when hydrated with High Conductivity water, such as ocean water. A liquid-impermeable cover sheet is adhered to the upper major surfaces of the filled copolymer-carrying geotextile to provide a primary high conductivity water barrier layer that, if ruptured, is sealed by the swell of an underlying layer of water-insoluble, partially cross-linked acrylamide/acrylic acid copolymer.


Patent
AMCOL International | Date: 2015-04-08

Oil, grease, and other hydrocarbons which are emulsified and/or entrained in water can be removed by first removing any solids from the water and then passing the contaminated water through media configured to coalesce the hydrocarbon contaminants. The coalesced hydrocarbon contaminants are allowed to float above the water, at which point the hydrocarbon contaminants can easily be removed from the water.
