Abstract:
Compatible copolymer-containing compositions are prepared by the reaction of a salicylate-capped polyphenylene ether, preferably prepared by reaction of a polyphenylene ether with trimellitic anhydride phenyl salicylate ester, with a polyarylene sulfide containing amine groups, preferably prepared by the reaction of a polyarylene sulfide with a disulfide containing amine groups. The compositions may also contain polyphenylene ether-compatible impact modifiers.
Abstract:
In a method for treating a contaminated fluid stream, a characteristic of a flow of the composition to a carbon adsorption zone (12) is sensed. The sensing is remotely monitored to determine a treatment for the contaminated fluid stream. The contaminated fluid stream is then treated according to the monitoring. A system (10) for treating a contaminated fluid stream comprises a sensor (36) that senses a characteristic of a flow of a contaminated fluid stream prior to treatment and a monitor (24) to receive information concerning the characteristic from the sensor (36) and to consequently control the carbon adsorption zone (12) to treat the contaminated fluid stream. The monitor (24) is situated at a location remote from the carbon adsorption zone (12).
Abstract:
Methods for separating, monitoring, identifying, and/or quantifying a plurality of ionic species in a mixture are disclosed herein. The ionic species can include a plurality of amines in an industrial fluid. The methods can include a first chromatography step, a second chromatography step, and optionally, a third chromatography step. The first chromatography step and second chromatography step can be performed simultaneously, for example in a dual channel apparatus, such that the method can be performed in less than about 24 hours. Disclosed herein are also methods for efficiently operating a refinery.

Abstract:
A contaminated aqueous composition is withdrawn from a groundwater extraction well (6) and the groundwater is treated in a pump and treat system (5, 9) to remove a contaminant. The treating of the aqueous composition is monitored from a location remote from the groundwater extraction well (6) and the treating is adjusted to remove a contaminant in accordance with the monitoring. A system (5, 9) to treat a contaminated aqueous composition comprises a capture zone to intercept a contaminated aqueous composition and a surface pump and treat system to receive and treat the contaminated aqueous composition form the capture zone. The system also includes a sensor that senses a contaminant in the contaminated aqueous composition and a monitor (55) to receive information concerning the contaminant form the sensor and to consequently control the pump and treat system to treat the contaminated aqueous composition. The monitor (55) is situated at a location remote from the pump and treat system (5, 9).
Abstract:
On prépare des compositions compatibles contenant un copolymère, en faisant réagir un éther de polyphénylène recouvert de salicylate, préparé de préférence par la réaction d'un éther de polyphénylène avec un ester de salicylate phénylique anhydride trimellitique, avec un sulfure de polyarylène contenant des groupes amine, de préférence préparé par la réaction d'un sulfure de polyarylène avec un bisulfure contenant des groupes amine. Ces compositions peuvent également contenir des modificateurs d'impact compatibles avec l'éther de polyphénylène.
