Abstract

The humidity of a gas within a closed system is maintained at constant level by providing a saturated salt solution within a lower chamber in communication with an upper chamber conjointly defined by upper and lower container sections in sealing contact with each other to establish a closed container. A partition wall separates the salt solution from the test region in the upper chamber. A tube extending through the partition plate allows humidified gas to pass from the lower to the upper chamber. A glass wool plug or membranous material within the tube prevents migration of salt into the test region.

Apparatus for adjusting and maintaining humidity of a gas at a constant value within a closed system

Technical Report Walters, R R; Abernathy, B

An improved apparatus was developed for maintaining the humidity of a gas at a constant value within a closed system for long periods of time by using saturated salt solutions and isolating the sample environment from the salt environment. This apparatus avoids many problems associated with humidity/temperature chambers and off-the-shelf laboratory equipment, such as desiccators, that are being used for environmental studies under controlled conditions of humidity and temperature. 3 refs., 2 figs.
Apparatus and method for maintaining multi-component sample gas constituents in vapor phase during sample extraction and cooling

Patent Felix, Larry Gordon; Farthing, William Earl; Irvin, James Hodges; ...

A dilution apparatus for diluting a gas sample. The apparatus includes a sample gas conduit having a sample gas inlet end and a diluted sample gas outlet end, and a sample gas flow restricting orifice disposed proximate the sample gas inlet end connected with the sample gas conduit and providing fluid communication between the exterior and the interior of the sample gas conduit. A diluted sample gas conduit is provided within the sample gas conduit having a mixing end with a mixing space inlet opening disposed proximate the sample gas inlet end, thereby forming an annular space between the samplemore » « less

Method and apparatus for maintaining condensable constituents of a gas in a vapor phase during sample transport

Patent Felix, Larry Gordon; Farthing, William Earl; Irvin, James Hodges; ...

A system for fluid transport at elevated temperatures having a conduit having a fluid inlet end and a fluid outlet end and at least one heating element disposed within the conduit providing direct heating of a fluid flowing through the conduit. The system is particularly suited for preventing condensable constituents of a high temperature fluid from condensing out of the fluid prior to analysis of the fluid. In addition, operation of the system so as to prevent the condensable constituents from condensing out of the fluid surprisingly does not alter the composition of the fluid.

Method and apparatus maintaining multi-component sample gas constituents in vapor phase during sample extraction and cooling

Patent Farthing, William Earl [Pinson, AL]; Felix, Larry Gordon [Pelham, AL]; Snyder, Todd Robert [Birmingham, AL]

An apparatus and method for diluting and cooling that is extracted from high temperature and/or high pressure industrial processes. Through a feedback process, a specialized, CFD-modeled dilution cooler is employed along with real-time estimations of the point at which condensation will occur within the dilution cooler to define a level of dilution and diluted gas temperature that results in a gas that can be conveyed to standard gas analyzers that contains no condensed hydrocarbon compounds or condensed moisture.
