Abstract
A regenerable filter for removing low molecular weight polymeric material from a fluid sample stream that is to be directed to an analyzer comprising a filter bed of particles of a synthetic polymer which at the temperature employed in the filter does not melt or react with or dissolve in the sample stream. Also disclosed is a fluid analysis system comprising said regenerable filter in conjunction with an analyzer.
Claims20
A regenerable filter for use in removing low molecular weight polymers from a fluid stream comprising a receptacle having an inlet and an outlet, a filter bed lying between said inlet and said outlet wherein said filter bed comprises particles of synthetic polymer selected from polytetrafluoroethylene and polyarylene sulfide which at the temperature employed in the filter does not melt or react with or dissolve in the fluid sample.
A fluid anaylsis system comprising a regenerable filter comprising a receptacle having an inlet and a outlet and a filter bed lying between said inlet and said outlet wherein said filter bed comprises particles of synthetic polymer which at the temperature employed in the filter does not melt or react with or dissolve in the sample fluid, first conduit means for providing sample fluid to the inlet of said filter, an analyzer means, second conduit means for carrying filtered sample fluid to said analyzer means, and means for providing regenerating fluid to said regenerable filter.
A fluid analysis system comprising,
- first and second regenerable filters each comprising a receptacle having an inlet and an outlet, and a filter bed interposed between said inlet and said outlet, wherein said filter bed comprises particles of synthetic polymer which at the temperature employed in the filter do not melt or react with or dissolve in the sample fluid,
- an analyzer means capable of analyzing at least a portion of filtered fluid sample,
- conduit means for supplying fluid sample to said regenerable filters,
- valve means for controlling the flow of fluid sample to said regenerable filters,
- conduit means for conveying filtered fluid sample to said analyzer,
- conduit means for conveying regenerating fluid to said regenerable filters,
- valve means for controlling the flow of regenerating fluid to said regenerable filters,
- conduit means for conveying used regenerating fluid away from said regenerable filters,
- a valve controller adapted to operate the various valve means so that when one regenerable filter is being used to filter said fluid sample the other regenerable filter is being contacted with regenerating fluid.
