to safely remove the catalysts from
00:00:09.310 00:00:09.320 hydrotreating or hydro processing
00:00:11.440 00:00:11.450 reactors refiners are faced with the
00:00:13.720 00:00:13.730 problem of spent catalyst that contains
00:00:15.970 00:00:15.980 active metal sulfides that can react
00:00:18.609 00:00:18.619 with oxygen when exposed to air these
00:00:21.639 00:00:21.649 reactions lead to the release of toxic
00:00:24.279 00:00:24.289 sulfur dioxide gas the exothermic
00:00:27.370 00:00:27.380 reactions will heat the catalyst and may
00:00:29.739 00:00:29.749 result in spontaneous ignition catnap
00:00:33.700 00:00:33.710 utilizes our patented technology along
00:00:36.580 00:00:36.590 with a proprietary chemical to passivate
00:00:39.119 00:00:39.129 pyrophoric or self heating catalyst this
00:00:42.610 00:00:42.620 allows for unload in an air atmosphere
00:00:45.130 00:00:45.140 the passivated catalysts can improve the
00:00:48.069 00:00:48.079 flow characteristics that facilitate
00:00:50.410 00:00:50.420 removal and other subsequent handling
00:00:52.720 00:00:52.730 the treated catalyst can be regenerated
00:00:55.389 00:00:55.399 catnap eliminates catalyst dust and
00:00:58.090 00:00:58.100 fines and reduces attrition during
00:01:00.520 00:01:00.530 catalyst removal and packaging this
00:01:04.240 00:01:04.250 results in a significantly reduced risk
00:01:07.270 00:01:07.280 because the need for working in inert
00:01:09.460 00:01:09.470 atmospheres is eliminated mitigating
00:01:12.819 00:01:12.829 potential volatile hydrocarbon lower
00:01:15.280 00:01:15.290 explosive limit or LEL issues the
00:01:19.270 00:01:19.280 cost-saving of not having to use
00:01:21.010 00:01:21.020 nitrogen for inert entry works
00:01:23.670 00:01:23.680 eliminating catalyst unloading
00:01:25.899 00:01:25.909 interruptions due to oxygen intrusion a
00:01:28.859 00:01:28.869 faster reactor cooldown due to the
00:01:31.870 00:01:31.880 superior heat transfer capability of
00:01:34.270 00:01:34.280 liquid cooling more rapid units shut
00:01:37.719 00:01:37.729 down by eliminating hot hydrogen
00:01:40.090 00:01:40.100 stripping eliminating exposure to toxic
00:01:43.749 00:01:43.759 and pyrophoric dust reducing dust
00:01:46.990 00:01:47.000 complications such as baghouse plugging
00:01:49.660 00:01:49.670 or fires cat techs catnap technology
00:01:54.069 00:01:54.079 allows for a safer faster and more
00:01:56.740 00:01:56.750 cost-effective method for either
00:01:58.569 00:01:58.579 skimming or full catalyst unloading
00:02:02.200 00:02:02.210 the application of catnap technology is
00:02:05.450 00:02:05.460 part of the reactors shutdown procedure
00:02:07.760 00:02:07.770 it utilizes the injection and absorption
00:02:10.790 00:02:10.800 of a chemical inhibitor while cooling
00:02:13.400 00:02:13.410 the unit down under oil circulation each
00:02:17.180 00:02:17.190 unit must be customized according to its
00:02:19.790 00:02:19.800 design and operation in general the
00:02:22.729 00:02:22.739 procedure is as follows the feed rate of
00:02:26.449 00:02:26.459 the reactor is reduced and the reactor
00:02:28.729 00:02:28.739 is allowed to start cooling down a
00:02:31.690 00:02:31.700 qualified carrier oil from the refiner
00:02:34.580 00:02:34.590 is introduced to flush out the normal
00:02:37.009 00:02:37.019 process feed and the unit is put on
00:02:39.530 00:02:39.540 liquid recycle the proprietary catnap
00:02:43.640 00:02:43.650 organic chemical is injected into the
00:02:46.039 00:02:46.049 recycle oil stream coating the catalyst
00:02:49.220 00:02:49.230 pellets the carrier oil and chemical are
00:02:53.120 00:02:53.130 circulated and recycled to allow the
00:02:55.789 00:02:55.799 unit to cool to the appropriate target
00:02:58.339 00:02:58.349 temperature this cooling method is
00:03:00.559 00:03:00.569 faster than circulating hydrogen when
00:03:04.339 00:03:04.349 the target temperature has been
00:03:05.690 00:03:05.700 established the circulation is stopped
00:03:08.240 00:03:08.250 and the unit is de-oiled the reactor is
00:03:13.069 00:03:13.079 degassed as per normal operating
00:03:15.530 00:03:15.540 procedure the reactor is purged with dry
00:03:19.819 00:03:19.829 air and measurements are taken for toxic
00:03:22.550 00:03:22.560 or flammable gases trained cat tech
00:03:26.690 00:03:26.700 personnel outfitted with life support
00:03:29.030 00:03:29.040 equipment for added safety then enter
00:03:31.699 00:03:31.709 under air and not under life threatening
00:03:34.370 00:03:34.380 nitrogen atmosphere conditions at this
00:03:37.640 00:03:37.650 point the catalyst is passivated with
00:03:40.099 00:03:40.109 minimal risk of dangerous self heating
00:03:42.699 00:03:42.709 since the catalyst is treated there is
00:03:45.770 00:03:45.780 no dust to deal with and the catalyst
00:03:48.379 00:03:48.389 can be removed by either dumping through
00:03:50.539 00:03:50.549 exit nozzles or vacuuming
00:03:53.850 00:03:53.860 the product can then be safely
00:03:55.980 00:03:55.990 transported to off-site locations in
00:03:58.530 00:03:58.540 bins or drums the reactor is now ready
00:04:02.850 00:04:02.860 for inspection and repairs as catnap
00:04:06.630 00:04:06.640 uses an organic chemical to coat the
00:04:09.030 00:04:09.040 catalysts the catalyst can be
00:04:10.920 00:04:10.930 regenerated off-site by most
00:04:13.290 00:04:13.300 regeneration facilities success in
00:04:17.940 00:04:17.950 today's refining environment demands
00:04:20.340 00:04:20.350 safe and efficient operations catnap is
00:04:23.490 00:04:23.500 the only proven alternative to inert
00:04:25.890 00:04:25.900 entry for safely removing reactive
00:04:28.620 00:04:28.630 catalysts under air without sacrificing
00:04:31.560 00:04:31.570 the remaining life of the catalyst
00:04:34.580 00:04:34.590 catnap is safer because it eliminates
00:04:37.740 00:04:37.750 inert entry and pyrophoric dust is
00:04:41.610 00:04:41.620 faster because it reduces the unit
00:04:44.250 00:04:44.260 shutdown time and allows for faster
00:04:46.860 00:04:46.870 unloading saves cost because it reduces
00:04:50.790 00:04:50.800 lost production by shortening the
00:04:52.740 00:04:52.750 turnaround time and eliminating nitrogen
00:04:55.410 00:04:55.420 expenses for inert entry has better
00:04:58.980 00:04:58.990 reliability because many of the
00:05:01.020 00:05:01.030 complications and delays associated with
00:05:03.450 00:05:03.460 inert entry dust and reactive catalysts
00:05:06.810 00:05:06.820 are eliminated Kath Tech has a proven
00:05:10.620 00:05:10.630 record unmatched by any other catalyst
00:05:13.500 00:05:13.510 handler in the industry the catnap
00:05:16.140 00:05:16.150 technology has serviced hundreds of
