    摘要： A process and a device for the continuous extraction and analysis of chemical substances from solute fluid using membrane is characterized by passing solute fluid 14 through housing 20 on one side of a semipermeable structure 19 and simultaneously passing extracting fluid 11 through the housing on the other side of the semipermeable membrane structure. Substances passing from solute fluid through the semipermeable membrane structure into the extracting fluid are delivered by the extracting fluid as carrier, into a sorbing phase 27. Cooling 28 and heating 24 of the sorbing phase allows substances to be concentrated and detected by detector 50 and to be continuously monitored. Extracting fluid may be a gas or a pressurized dense gas. Extraction using pressurized dense gas and membrane is achieved by maintaining the pressure of the solute fluid and the pressurized dense gas within a high pressure housing substantially equal. Previously, solute fluids were analyzed using batch processes with liquid-liquid extraction, extraction cartridges or purge and trap. Continuous extraction and analysis using membranes eliminates the use of organic solvents and provides inexpensive and continuous monitoring of volatile, semi-volatile, non-volatile and polar compounds in water and other fluids.

    摘要： A solid body having extremely narrow passages formed therein for the separation and conveyance of gases by surface diffusion. Because of the relatively high flow resistance resulting from the extremely small cross sections of the passages, the gas conveyance through the solid body can be performed substantially exclusively by surface diffusion. Only those gas particles which are adsorbed on the solid body or on the wall of the passages will be conveyed through the solid body. The surface diffusion can be controlled by suitable selection of the gas/solid body combination. The diffusion is influenced particularly by the temperature of the solid body. When, in the case of a two-gas mixture, the solid body is heated to a temperature above the desorption temperature of one of the gases and below the desorption temperature of the other gas, only the gas particles of the adsorbed gas are conveyed on the passage walls by surface diffusion.

    摘要： A self-supported low pressure drop hollow fiber membrane panel includes a pair of layers of non-permeable material having opposite external and internal sides, and a multiplicity of hollow fibers of permeable material extending between and in generally transverse relationship to the layers of non-permeable material. Opposite end portions of the hollow fibers are encapsulated by the respective layers of non-permeable material and are open at the external sides thereof. Elongated portions of the hollow fibers have elongated internal bores providing flow communication between the open opposite end portions of the hollow fibers. The elongated portions of the hollow fibers extend between the internal sides of the respective layers of non-permeable material. The lengths of the elongated portions of the hollow fibers are substantially less than each of the length and width dimensions of the layers of non-permeable material. A contactor module for gas-gas, gas-liquid and liquid-liquid mass transfer systems employs the hollow fiber membrane panel.
