US Patent:

40550010, Oct 25, 1977

Filed:

Sep 25, 1975

Appl. No.:

5/616773

Inventors:

Eric O. Forster - Scotch Plains NJ
Peter J. Creighton - Mendham NJ

Assignee:

Exxon Research & Engineering Co. - Linden NJ

International Classification:

F26B 334
F26B 700

US Classification:

34 1

Abstract:

Volatile polar vehicles such as water or organic solvents, are removed from nonpolar materials by passing said material through at least one pneumatic conveyor resonating cavity operating at a microwave frequency of about 600 to about 50,000 MHZ. For example, a polymer such as polyvinyl chloride may be dried by conveying the polymer through said pneumatic conveyor operating at a frequency of 915 MHZ for a time sufficient to reduce the volatiles content to about 5 wt. % and subsequently conveying the partially dried material through a second pneumatic conveyor resonating cavity operating at a microwave frequency of 2450 MHZ for a time sufficient to reduce the polar vehicle content to below 0. 5 wt. %. The resonating cavities may constitute a single pneumatic conveyor having zones operating at different frequencies, said zones being isolated from one another by microwave suppressors such as "eggcrate" type suppressors. Alternately, several pneumatic conveyor systems, each operating at a different frequency, may be used.

Filed:

Sep 9, 1974

Appl. No.:

5/504143

Inventors:

Eric O. Forster - Scotch Plains NJ
William R. L. Thomas - Holmdel NJ

Assignee:

Exxon Research and Engineering Company - Linden NJ

International Classification:

G01N 900
F17C 1302

US Classification:

73 32R

Abstract:

A system has been invented for the continuous determination of density of cryogenic liquids such as LPG and LNG to within. +-. 0. 1% or better using differential capacitance measurements. This system would allow the detection of incipient density inversions in storage tanks and the accurate determination of quantities transferred from ship to shore to customers.
