摘要： A headspace sampling system monitors materials in wastewater. The headspace sampling system comprises a sample receptacle that can contain a wastewater sample; a sparger chamber vapor column; a sample receptacle cover assembly that connects the sparger chamber vapor column to the sample receptacle; a sparger tube; at least one sensing device; and at least one analytic device. The sparger tube and the sample receptacle define a headspace. The sparger chamber vapor column is in communication with the sample receptacle and is closed by a sparger chamber vapor column cover at a second end that is opposed to the sample receptacle. The sparger tube extends into the sample receptacle and the wastewater sample in the sample receptacle. The sparger tube is connected to a source of inert gas at a first end opposed to the sample receptacle and comprises a dispersion device at an end opposed to the first end. The sensing device is disposed in the headspace sampling system in the headspace. The analytic device in communication with the least one sensing device. Inert gas can flow through the sparger tube into the wastewater sample to separate materials from the wastewater, the sparged materials entering the headspace of the headspace sampling system. The sparged materials are sensed by the sensing device thus providing material signal characteristics, which can be analyzed by the analytic device to determine characteristics of the material from the material signal characteristics and provide information about the characteristics of the material.

摘要： A process for making bis(ether anhydrides) employs alkylamines having low melting temperatures thus allowing for novel intermediate process steps for preparing bis(ether anhydrides). The alkylamines have alkyl groups which contain at least three carbon atoms and have boiling temperatures in the range of 48 to 250.degree. C. at atmospheric pressure. As a result of using these amines, liquid alkylamines now can be employed in the imidization process step. The N-alkyl nitrophthalimides prepared from the recovered imidization product according to this invention can now be purified using liquid/liquid extraction or vacuum distillation. The alkyl nitrophthalimides prepared according to this invention provide for displacement reactions which now can be run at a high solids level. Likewise, the exchange reaction can be run at a higher solids level, and thus achieves an efficiency level which is higher than conventional processes.

摘要： In a method for treating a contaminated fluid stream, a characteristic of a flow of the composition to a carbon adsorption zone 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 for treating a contaminated fluid stream comprises a sensor that senses a characteristic of a flow of a contaminated fluid stream prior to treatment and a monitor to receive information concerning the characteristic from the sensor and to consequently control the carbon adsorption zone to treat the contaminated fluid stream. The monitor is situated at a location remote from the carbon adsorption zone.

摘要： A contaminated aqueous composition is withdrawn from a groundwater extraction well and the groundwater is treated in a pump and treat system to remove a contaminant. The treating of the aqueous composition is monitored from a location remote from the groundwater extraction well and the treating is adjusted to remove a contaminant in accordance with the monitoring. A system 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 from the capture zone. The system also includes a sensor that senses a contaminant in the contaminated aqueous composition and a monitor to receive information concerning the contaminant from the sensor and to consequently control the pump and treat system to treat the contaminated aqueous composition.

摘要： An on-line sparging sampling system and method sparges polar and non-polar volatile organic compounds from aqueous discharge. The system comprises a network of tubular members that are interconnected to each other to define a fluid passage, in which the network of tubular members comprises an inlet for influent aqueous discharge into the network of tubular members and an outlet for discharge of aqueous discharge from the on-line sparging sampling and monitoring system; a sparger disposed in the network of tubular members, in which the sparger is disposed between the inlet and the outlet of the aqueous discharge so that aqueous discharge flows by the sparger, the sparger providing inert non-reactive gas to the on-line sparging sampling and monitoring system; and at least one analytic device connected to the on-line sparging sampling and monitoring system for analyzing volatile organic compounds in the aqueous discharge. The aqueous discharge forms an aqueous discharge portion and a headspace during flow through the network of tubular members. The sparger provides the inert non-reactive gas to flow through the aqueous discharge portion. The inert non-reactive gas partitions volatile organic compounds from the aqueous discharge portion to the headspace. Thus, polar and non-polar volatile organic compounds can be analyzed by the at least one analytic device.

摘要： An improved method and apparatus for monitoring the concentration of contaminants, including volatile organic compounds, in groundwater is provided comprising a semipermeable membrane defining an inner chamber. The chamber is carried within a mesh protective sleeve of cover to prevent abrasion or puncture of the chamber. The membrane is permeable to contaminants but impermeable to a reference fluid, which is distilled water. The method of sampling comprises placing the semipermeable membrane chamber, which contains the reference fluid, in contact with contaminated groundwater, thereby allowing contaminants to diffuse through the semipermeable membrane.
