Abstract: This invention relates to an alkoxylated calixarene resin comprising one or more modified calixarene alkoxylate compounds. The invention also relates to a process for preparing a solubilized alkoxylated calixarene resin comprising reacting a phenolic resin mixture, comprising linear phenolic resins and calixarene compounds having phenolic hydroxyl groups, with one or more epoxide-containing compounds to alkoxylate one or more of the phenolic hydroxyl groups of the calixarene compounds to form a solubilized phenolic resin mixture, and reacting the solubilized phenolic resin mixture with one or more alkylene oxides.

Abstract: The present invention is directed to the removal of one or more selected target materials, in particular a physiologically active compound contaminant, from various streams using a rare earth fixing agent.

Abstract: This invention relates to compositions and a process for stabilizing or improving the solubility of a phenolic resin containing a mixture of linear phenolic resins and calixarenes in a hydrocarbon solvent. This invention also relates to a paraffin-containing fluid composition comprising this stabilized (solubilized) calixarene resin. The invention also relates to methods for dispersing paraffin crystals, inhibiting paraffin crystal deposition, or treating a well or vessel to reduce the deposition of paraffin crystals, with a resin composition containing this stabilized (solubilized) calixarene resin.

Abstract: A petroleum-based fluid sample may be centrifuged in a centrifuge vial where a light may be passed through the petroleum-based fluid sample to identify an amount of transmitted light at two or more time intervals. The stability of the foulant(s) and/or efficacy of the foulant inhibitors to prevent the destabilization of the foulants may be determined by comparing a change in the amounts of transmitted light through the petroleum-based fluid sample. The petroleum-based fluid sample may include a petroleum-based fluid, at least one foulant, and an optional additive for destabilizing the foulant(s). The additive may be or include a first component, such as but not limited to n-alkanes, iso-alkanes, alkenes, alkynes, cyclo-alkanes, natural gas, natural gas condensate, alcohols, ethers, ketones, organic acids, acetates, carbon dioxide, and combinations thereof.

Abstract: This disclosure relates generally to methods and rare earth-containing additives for removing target materials in the form of hydroxides, carbonates, hydrates, or oxyhydroxyls from, a typically aqueous, liquid medium.

Abstract: This disclosure relates generally to methods and compositions for removing contaminants from streams and is particularly concerned with methods and compositions for removing contaminants from municipal wastewaters, municipal drinking waters and recreational waters. The present disclosure is to particulate cerium, more particularly to particulate cerium (IV) formed by an in situ oxidative process and to a method for removing target materials from a target material-containing stream using particulate cerium formed in situ.

Abstract: The present disclosure includes an embodiment to a method for treating water and/or a water handling system to decrease deposit formation and/or to remove a deposit. More particularly, to a method for treating water and/or a water handling system with one or more rare earths to decrease deposit formation and/or to remove a deposit. Struvite is an example of deposit material that can be removed and/or deposition inhibited by treating a water and/or water handling system with one or more earths.
