Thermox and WDG UOP Series
1980
Thermox, in conjunction with the UOP Process Division, developed
the WDG-III UOP to monitor the gaseous atmosphere during a
regeneration cycle of UOP’s Licensed Continuous Catalyst Regen-
eration process. With their technical guidance this analyzer evolved
to the current model WDG-IV UOP/RP.
1999
UOP and Thermox addressed plugging and corrosion issues with
the external sample return line which is outside the scope of
our supply. The revised UOP Project Specification 630 allows the
close-coupled, nitrogen-aspirated, return-to-process design of the
Thermox model WDG-IV UOP/RP (or an in-situ probe design) to be
used to measure oxygen content of the process. This eliminated
the need for the external sample return line and the sample flow
sensor used to check for plugging in the return line that were part
of the WDG-III and WDG-IV UOP analyzer designs. Since the process
piping of the CCR is 316 stainless steel, and the process was adjust-
ed to include nitrogen blanketing at shutdown, UOP decided that
Hastelloy C was no longer mandatory for the process-wetted parts.
The standard analyzer is now constructed of 316 SS, but Hastel-
loy C is still available as an option.
2007
Thermox added an option to the WDG-IV UOP to include isolation
valves on the inlet and outlet process connections. This option
allows for maintenance of the WDG-IV UOP analyzer without shut-
ting down the process.
2019
Thermox updated the instrument’s electronics package and
renamed the product WDG-V UOP. The new electronics package
includes additional diagnostics and meets the ROHS compliance
directive. The AMEVision Controller replaces the Series 2000 Con-
troller for the instrument as well. It includes a color LED display and
additional communications options.
