摘要： A method of removing at least one cationic dye from an aqueous solution. The method includes contacting the aqueous solution with an adsorbent comprising a water-insoluble membrane disposed on a substrate. The water-insoluble membrane comprises cross-linked humic acid, at least one alginate, and hydroxyethyl cellulose. The contacting forms a treated aqueous solution having a lower concentration of the at least one cationic dye relative to the aqueous solution.

摘要： Herein are described compositions useful in the purification of hydrocarbon-contaminated liquids (e.g., oil-contaminated water), methods of their manufacture, and methods of their use. In one instance, the composition can include a porous agricultural substrate selected from the group consisting of walnut shell, pecan shell, apricot pit, peach pit, corn cob, and a mixture thereof; the porous agricultural substrate having an external surface and pores, wherein the external surface is hydrophilic; and an organo-amine carried within the pores of the porous agricultural substrate. These compositions are utilized as regenerable filter media in place of, for example, ground walnut media.

摘要： Unconventional hydrocarbons production from shale and tight-sand formations unlocks vast new energy sources to the nation. However, public perception about excessive potable water use in hydro-fracturing and possible pollution routes in discharging and reusing produced water (flow-back water) promotes state's stringent regulations and opens the door to develop effective produced water treatment methods. This invention is therefore aimed at properly treating produced water to avert health and environmental liabilities and convert economic losses to useful by-products using innovative methods to de-oil, de-scale, and de-salt produced water.

摘要： A water treatment system is provided that includes a brine tank and a resin tank and a control valve in operative connection with the tanks. The control valve includes a piston that is operative by a first motor to move between different positions to change the flow of water through orifices in the control valve, and a brine valve that is operative by a second motor to open and close the passage between the brine tank and resin tank. The second motor operates the brine valve independently of the operation of the piston by the first motor.

摘要： The present invention relates to a process for recovering polar hydrocarbons from non-polar hydrocarbons, such as aromatics from non-aromatics, naphthenes from paraffins and isoparaffins, or olefins from paraffins and isoparaffins, in feed mixtures containing at least a measurable amount of heavier hydrocarbons. According to the invention, an improved extractive distillation (extractive-distillation) process is disclosed for recovering aromatic hydrocarbons including benzene, toluene, and xylenes from heavy (C9+) hydrocarbons. The invention also relates to an improved extractive-distillation process for recovering mainly benzene and toluene from the C6-C7 petroleum streams containing at least a measurable amount of C8+ hydrocarbons. This invention is further directed toward the regeneration and recovery of the extractive-distillation solvent utilized to recover and purify the aromatic hydrocarbons from the petroleum stream containing at least a measurable amount of hydrocarbons heavier than the intended product.
