Apparatus and method for monitoring of gas having stable isotopes

Clegg, Samuel M; Fessenden-Rahn, Julianna E

Title: Apparatus and method for monitoring of gas having stable isotopes

Abstract

Gas having stable isotopes is monitored continuously by using a system that sends a modulated laser beam to the gas and collects and transmits the light not absorbed by the gas to a detector. Gas from geological storage, or from the atmosphere can be monitored continuously without collecting samples and transporting them to a lab.

Liquid-phase thermal diffusion isotope separation apparatus and method having tapered column

Patent Rutherford, William M [Dayton, OH]

A thermal diffusion counterflow method and apparatus for separating isotopes in solution in which the solution is confined in a long, narrow, vertical slit which tapers from bottom to top. The variation in the width of the slit permits maintenance of a stable concentration distribution with relatively long columns, thus permitting isotopic separation superior to that obtainable in the prior art.

Method and apparatus for noble gas atom detection with isotopic selectivity

Patent Hurst, G Samuel [Oak Ridge, TN]; Payne, Marvin G [Harriman, TN]; Chen, Chung-Hsuan [Knoxville, TN]; ...

Apparatus and methods of operation are described for determining, with isotopic selectivity, the number of noble gas atoms in a sample. The analysis is conducted within an evacuated chamber which can be isolated by a valve from a vacuum pumping system capable of producing a pressure of 10.sup.-8 Torr. Provision is made to pass pulses of laser beams through the chamber, these pulses having wavelengths appropriate for the resonance ionization of atoms of the noble gas under analysis. A mass filter within the chamber selects ions of a specific isotope of the noble gas, and means are provided to acceleratemore » « less

Method and apparatus for producing pyrolysis oil having improved stability

Patent Baird, Lance A.; Brandvold, Timothy A.; Muller, Stefan

Methods and apparatus to improve hot gas filtration to reduce the liquid fuel loss caused by prolonged residence time at high temperatures are described. The improvement can be obtained by reducing the residence time at elevated temperature by reducing the temperature of the pyrolysis vapor, by reducing the volume of the pyrolysis vapor at the elevated temperature, by increasing the volumetric flow rate at constant volume of the pyrolysis vapor, or by doing a combination of these.
