you
00:00:00.760 00:00:00.770 [Music]
00:00:17.190 00:00:17.200 so I'm here today to talk to you about
00:00:19.180 00:00:19.190 what surface air coolers and how they be
00:00:21.580 00:00:21.590 used to provide the lowest possible
00:00:23.580 00:00:23.590 process outlet temperatures for the
00:00:26.140 00:00:26.150 biological treatment of eczema illnesses
00:00:29.290 00:00:29.300 Fahrenheit throughout my presentation
00:00:31.320 00:00:31.330 apologize I'm most comfortable with that
00:00:33.369 00:00:33.379 the Celsius will be on the slide screen
00:00:39.509 00:00:39.519 so the problem we're trying to address
00:00:41.320 00:00:41.330 here is to keep the bugs happy we like
00:00:44.110 00:00:44.120 to say the wastewater effluent must be
00:00:46.780 00:00:46.790 treated with biological bacteria or the
00:00:49.450 00:00:49.460 bugs before the wastewater can be
00:00:52.389 00:00:52.399 released to the environment these bugs
00:00:54.760 00:00:54.770 eat the hydrocarbons that contaminate
00:00:58.389 00:00:58.399 the wastewater and must be eliminated
00:01:00.819 00:01:00.829 before they're discharged and these
00:01:03.610 00:01:03.620 books lose their effectiveness
00:01:05.499 00:01:05.509 until they can also die above about 95
00:01:08.859 00:01:08.869 fair in certain parts of the world very
00:01:13.660 00:01:13.670 difficult to reach this temperature on
00:01:16.389 00:01:16.399 some of the hottest months of the year
00:01:18.270 00:01:18.280 other technologies when dried polluters
00:01:21.250 00:01:21.260 may only dated about a minor in love in
00:01:23.109 00:01:23.119 Fahrenheit with certain things going to
00:01:24.609 00:01:24.619 work combination points our heat
00:01:27.039 00:01:27.049 exchanger my dated 96 but it was it was
00:01:30.880 00:01:30.890 carefully I think as easily got
00:01:33.249 00:01:33.259 customers 290 parent lead outlet and
00:01:36.310 00:01:36.320 00:01:39.719 00:01:39.729 another problem that our customers faces
00:01:42.310 00:01:42.320 is wastewater is a high bottling process
00:01:47.230 00:01:47.240 stream I can easily clog other types of
00:01:50.890 00:01:50.900 heat exchangers but it frames Shaun suit
00:01:53.710 00:01:53.720 I was never very reduce your exchanger
00:01:57.249 00:01:57.259 performance and clause maintenance
00:01:59.590 00:01:59.600 issues it's you know having to clean the
00:02:02.319 00:02:02.329 Kalani
00:02:03.580 00:02:03.590 lot of our fineries were also at very
00:02:05.800 00:02:05.810 strict requirements there's as me team
00:02:08.080 00:02:08.090 out each jolly or in Europe PD depending
00:02:13.240 00:02:13.250 the location especially the Middle East
00:02:14.770 00:02:14.780 I may have limited fresh water makeup
00:02:17.680 00:02:17.690 sources in order to use for that record
00:02:23.940 00:02:23.950 so I'm an expert on the actual water
00:02:26.860 00:02:26.870 treatment process I'm here to talk about
00:02:28.660 00:02:28.670 heat exchanger
00:02:29.620 00:02:29.630 but basically what we're trying to do is
00:02:31.540 00:02:31.550 again pull the wastewater before it
00:02:35.800 00:02:35.810 reaches the bugs so that the bugs can be
00:02:38.470 00:02:38.480 most effective so the solution of new
00:02:42.850 00:02:42.860 proposed is a custom engineered
00:02:44.980 00:02:44.990 closed-loop evaporative cooler we're a
00:02:49.240 00:02:49.250 specialized here in late rejection
00:02:51.820 00:02:51.830 through evaporation it's not sensitive
00:02:53.980 00:02:53.990 coin is leading and evaporate water off
00:02:58.270 00:02:58.280 of a new bundle surface the closed-loop
00:03:02.020 00:03:02.030 system is going to prevent contamination
00:03:03.880 00:03:03.890 and further provide low maintenance by
00:03:07.630 00:03:07.640 using materials that are resistance to
00:03:09.430 00:03:09.440 Florrick corrosion which is often
00:03:11.980 00:03:11.990 present in these wastewater streams from
00:03:16.750 00:03:16.760 one case study I'll talk briefly about
00:03:18.700 00:03:18.710 this major refinery the US Gulf Coast
00:03:22.720 00:03:22.730 this one happens to be in Louisiana we
00:03:24.940 00:03:24.950 also have installation from movies and
00:03:26.800 00:03:26.810 in Europe most recently in Belgium this
00:03:30.070 00:03:30.080 particular refinery was trying to
00:03:31.930 00:03:31.940 discharge but a 900 GPM of their
00:03:34.810 00:03:34.820 wastewater stream with very high levels
00:03:37.510 00:03:37.520 of self-importance and was where the wet
00:03:40.690 00:03:40.700 surface air cooler they were just going
00:03:42.520 00:03:42.530 through a lot of plate frames that they
00:03:44.560 00:03:44.570 were clogging they were following having
00:03:46.600 00:03:46.610 a lot of trouble with a high maintenance
00:03:48.360 00:03:48.370 and since we have several of these
00:03:50.890 00:03:50.900 installations throughout the Gulf Coast
00:03:52.750 00:03:52.760 and throughout the world really it it
00:03:55.660 00:03:55.670 gets the process how the temperature
00:03:57.040 00:03:57.050 they're looking for they can handle the
00:03:59.080 00:03:59.090 high fluoride high fouling stream it's a
00:04:03.190 00:04:03.200 very low maintenance system which
00:04:04.600 00:04:04.610 they're very happy about so brief
00:04:08.530 00:04:08.540 refresher on with the web pulpit is it's
00:04:10.510 00:04:10.520 a combination of the drywall for the
00:04:13.090 00:04:13.100 ambience and the humidity the web bulb
00:04:16.450 00:04:16.460 is the temperature of the water that
00:04:18.280 00:04:18.290 pre-exhaustion surface so we take it's a
00:04:21.310 00:04:21.320 mobile design day it's 96 Fahrenheit
00:04:23.950 00:04:23.960 tri-ball about 52 percent relative
00:04:26.320 00:04:26.330 humidity the web bulb is gonna be about
00:04:28.450 00:04:28.460 80 Fahrenheit a big difference here
00:04:30.970 00:04:30.980 between the night struggle and the heat
00:04:34.350 00:04:34.360 Fahrenheit wet bulb so if we compare
00:04:38.950 00:04:38.960 design conditions again a different type
00:04:41.710 00:04:41.720 of
00:04:42.140 00:04:42.150 that are available to dry air coolers
00:04:44.720 00:04:44.730 and rely primarily on me on cessful
00:04:47.420 00:04:47.430 cooling with a practical 50 degree
00:04:51.250 00:04:51.260 fahrenheit approach to that drug wall
00:04:53.540 00:04:53.550 means on this 96 degree day the coldest
00:04:57.170 00:04:57.180 that a dr borders indeed across this
00:04:59.030 00:04:59.040 outlet it's about my love apparently if
00:05:02.180 00:05:02.190 you looked at a more traditional cooling
00:05:03.980 00:05:03.990 tower plus heat exchanger to rely on a
00:05:06.500 00:05:06.510 combination of both latent and sensible
00:05:08.500 00:05:08.510 cooling combination practical approach
00:05:12.530 00:05:12.540 to be about 15 Fahrenheit which means
00:05:14.840 00:05:14.850 the cold is that your combination points
00:05:17.390 00:05:17.400 our exchangers in get you about nine
00:05:19.610 00:05:19.620 states there you now look at what's
00:05:22.460 00:05:22.470 observed for we rely only on lately
00:05:25.760 00:05:25.770 projection we get as low as five degrees
00:05:28.640 00:05:28.650 Fahrenheit most economical is about a 10
00:05:30.860 00:05:30.870 degree Fahrenheit approach to the wet
00:05:32.360 00:05:32.370 bulb which means we're going to get to
00:05:34.400 00:05:34.410 the lowest possible process outlet
00:05:35.960 00:05:35.970 temperature about ninety Fahrenheit
00:05:37.910 00:05:37.920 we're also going to have the lowest
00:05:40.220 00:05:40.230 electrical consumption much smaller fans
00:05:42.680 00:05:42.690 on smaller pots and while we will
00:05:45.920 00:05:45.930 require some water can you lower water
00:05:48.470 00:05:48.480 consumption compared to your going sour
00:05:50.690 00:05:50.700 huge changer again for the the wet
00:05:56.720 00:05:56.730 surface air cooler if you think of a
00:05:58.400 00:05:58.410 traditional Sheltie exchanger if you
00:06:01.520 00:06:01.530 remove the shell exposing buried suits
00:06:04.190 00:06:04.200 now to spray water over the
00:06:07.010 00:06:07.020 two-month-old surface and inducing an
00:06:09.440 00:06:09.450 airflow in the same direction as the
00:06:12.260 00:06:12.270 spray water that essentially somewhat
00:06:15.230 00:06:15.240 surface air cooler parts and evaporate
00:06:17.300 00:06:17.310 on this water for the process heat in
00:06:22.400 00:06:22.410 this quick video if you take your
00:06:24.320 00:06:24.330 traditional shell to get anger your
00:06:27.500 00:06:27.510 cooling tower all the process piping
00:06:30.200 00:06:30.210 that moves the cooling water between the
00:06:33.110 00:06:33.120 two you can see how we translate this is
00:06:36.140 00:06:36.150 a wet surface air for it
00:06:38.680 00:06:38.690 we start out holding the process
00:06:40.880 00:06:40.890 tightening remember the shell and she'll
00:06:42.950 00:06:42.960 to remove the cooling tower felt which
00:06:45.470 00:06:45.480 we do not need you take the spray pipe
00:06:47.780 00:06:47.790 you place it over top and rub two
00:06:49.850 00:06:49.860 bundles you align the family
00:06:52.580 00:06:52.590 next to the tubes removing a large
00:06:55.340 00:06:55.350 process long replace it with a much
00:06:58.040 00:06:58.050 smaller recirculated spray pump
00:07:00.080 00:07:00.090 00:07:03.400 00:07:03.410 traditional wet surface air cooler and
00:07:05.960 00:07:05.970 your two bundles on the right in the
00:07:08.720 00:07:08.730 middle your hot process will come in the
00:07:11.270 00:07:11.280 bottom stay inside the tubes the
00:07:13.370 00:07:13.380 closed-loop system pass back and forth
00:07:15.320 00:07:15.330 several times we can come out of topics
00:07:17.810 00:07:17.820 and bundles nice and cold we're going to
00:07:20.360 00:07:20.370 take the basement water take the
00:07:24.440 00:07:24.450 basement water recirculated with these
00:07:26.629 00:07:26.639 recirculating spray pumps over the top
00:07:29.030 00:07:29.040 of two bundles will fall back into the
00:07:31.070 00:07:31.080 system recirculate that with these fans
00:07:34.490 00:07:34.500 we will do some airflow down the same
00:07:36.950 00:07:36.960 direction of the spray water this
00:07:38.600 00:07:38.610 ensures that we get a good coverage over
00:07:40.760 00:07:40.770 the outside of the two bundles heavy
00:07:43.219 00:07:43.229 water droplets will fall back into the
00:07:45.950 00:07:45.960 basin be hot saturated air will turn
00:07:50.330 00:07:50.340 twice many degrees dropping more than
00:07:52.909 00:07:52.919 the water droplets out and hot saturated
00:07:56.690 00:07:56.700 air will be exhausted so if you go back
00:08:02.719 00:08:02.729 to the original problem now you're
00:08:05.029 00:08:05.039 looking at putting in a bathroom cooler
00:08:06.620 00:08:06.630 in here in this example the inlet
00:08:10.730 00:08:10.740 temperature is 150 Fahrenheit we're
00:08:12.860 00:08:12.870 going to niche down to about 290
00:08:14.150 00:08:14.160 Fahrenheit and in some applications
00:08:16.820 00:08:16.830 where you're looking to reduce or you
00:08:18.500 00:08:18.510 cannot have a fresh water source you can
00:08:20.960 00:08:20.970 actually use the wastewater discharge as
00:08:23.480 00:08:23.490 made up back into the wet surface
00:08:25.040 00:08:25.050 Airport so the main features and
00:08:31.790 00:08:31.800 benefits of the web surface air cooler
00:08:33.909 00:08:33.919 lowest possible process outlet
00:08:36.079 00:08:36.089 temperature monitoring the previous
00:08:37.579 00:08:37.589 skier spoke of needing a chiller to get
00:08:39.709 00:08:39.719 there
00:08:40.159 00:08:40.169 presumably they wouldn't need that they
00:08:42.500 00:08:42.510 use this the proven experience with high
00:08:47.000 00:08:47.010 fouling poor quality process strength
00:08:49.180 00:08:49.190 because mirrors are an engineered order
00:08:51.769 00:08:51.779 product we can design the internal to
00:08:54.680 00:08:54.690 velocities to be high enough to be able
00:08:57.410 00:08:57.420 to push that through and turn down
00:09:00.350 00:09:00.360 situations the original design case case
00:09:03.410 00:09:03.420 study with
00:09:04.300 00:09:04.310 GTM that customer head to bundles they
00:09:07.450 00:09:07.460 want to operate say 450 GPM that usually
00:09:11.019 00:09:11.029 close one of the two bundles operate
00:09:13.150 00:09:13.160 just through one to maintain those
00:09:15.100 00:09:15.110 sidelines
00:09:16.350 00:09:16.360 it's an engineered order product so most
00:09:19.330 00:09:19.340 customers care about SME but also
00:09:22.000 00:09:22.010 recently we did a the SL refinery
00:09:24.370 00:09:24.380 Antwerp here in Belgium required PDU
00:09:27.670 00:09:27.680 Griffith that the US Pacific we will
00:09:30.550 00:09:30.560 meet the relevant sections of AGI specs
00:09:34.060 00:09:34.070 as they apply to a web service airport
00:09:36.250 00:09:36.260 and it's to the low maintenance easy
00:09:39.340 00:09:39.350 maintain very rugged construction for a
00:09:43.300 00:09:43.310 long life motion wet surface air coolers
00:09:46.420 00:09:46.430 to last twenty thirty four years
00:09:50.760 00:09:50.770 proper material selection is required
00:09:54.060 00:09:54.070 proper chemical treatment is required
00:09:56.850 00:09:56.860 but very long life and very low
00:10:01.090 00:10:01.100 maintenance again
00:10:01.990 00:10:02.000 I already spoke about the turndown but
00:10:06.730 00:10:06.740 because of our engineer to order we can
00:10:08.770 00:10:08.780 build in redundancy some customers board
00:10:11.710 00:10:11.720 order completely redundant units but you
00:10:14.260 00:10:14.270 can kind of take its whatever level you
00:10:16.090 00:10:16.100 want
00:10:16.570 00:10:16.580 we're done for circulating straight
00:10:18.310 00:10:18.320 lungs at spared fans even spare two
00:10:22.540 00:10:22.550 bundles for very critical processes
00:10:25.180 00:10:25.190 where they actually cannot shut down you
00:10:27.940 00:10:27.950 can design enough we're done easing into
00:10:29.590 00:10:29.600 the system to ensure that the operation
00:10:32.290 00:10:32.300 you're doing while you're thinking about
00:10:34.630 00:10:34.640 the web service airport again very low
00:10:37.840 00:10:37.850 maintenance this is the design the
00:10:39.579 00:10:39.589 system this is its use
00:10:42.280 00:10:42.290 excuse the oppressor high flow of spray
00:10:44.470 00:10:44.480 nozzles which can often be repaired
00:10:46.270 00:10:46.280 while the unit is replaced I'm sorry
00:10:49.000 00:10:49.010 while the unit is still in operation
00:10:50.710 00:10:50.720 believe is oppose racism can offer an
00:10:55.449 00:10:55.459 access package so you can use spray
00:10:57.579 00:10:57.589 system make sure you're getting clear
00:10:59.470 00:10:59.480 coverage without having to enter the
00:11:01.690 00:11:01.700 structure there's no cooling tower fill
00:11:04.440 00:11:04.450 which can cause catastrophic issues in
00:11:08.230 00:11:08.240 some instances when you're dealing with
00:11:14.670 00:11:14.680 wastewater its high fouling
00:11:17.930 00:11:17.940 and ask the process fluid some of the
00:11:21.290 00:11:21.300 key benefits here is completely
00:11:23.810 00:11:23.820 cleanable two bundles with removable
00:11:27.200 00:11:27.210 headers on the left here these are
00:11:29.450 00:11:29.460 bolted on colors are remove the bolts
00:11:32.150 00:11:32.160 you can remove the covers and you can
00:11:34.190 00:11:34.200 see inside the tubes you see completely
00:11:36.830 00:11:36.840 through can be cleaned with all its or
00:11:39.800 00:11:39.810 just a rush to get in there as often as
00:11:44.300 00:11:44.310 the customer requires and then because
00:11:49.670 00:11:49.680 it's engineer to order we can cool
00:11:51.680 00:11:51.690 multiple process streams so depending on
00:11:54.620 00:11:54.630 achieve you can have one unit that can
00:11:57.260 00:11:57.270 cool waste water maybe a few other
00:12:00.160 00:12:00.170 auxilary loop coolers or else it's a
00:12:06.770 00:12:06.780 short list of some of the installations
00:12:09.100 00:12:09.110 naggers there are about 110 years so
00:12:11.870 00:12:11.880 we've worked with just about every
00:12:13.340 00:12:13.350 customer in every industry but this is
00:12:15.800 00:12:15.810 just a very short list set if it's in
00:12:18.260 00:12:18.270 place for some text says us called post
00:12:22.190 00:12:22.200 and very good a lot of excavation there
00:12:24.730 00:12:24.740 most recently in Saudi Arabia and also
00:12:27.530 00:12:27.540 Belgium now so I don't want to keep you
00:12:33.710 00:12:33.720 from lunched so any questions that's the
00:12:39.110 00:12:39.120 most in the to test although magnitude
00:12:41.390 00:12:41.400 of develop signature I just know feet
00:12:45.230 00:12:45.240 per second I apologize but we can design
00:12:47.750 00:12:47.760 whatever you want but we would try to
00:12:50.090 00:12:50.100 get about five to seven foot per second
00:12:53.440 00:12:53.450 yes is the content you know the residual
00:12:59.750 00:12:59.760 water that's only I don't know they work
00:13:03.230 00:13:03.240 directly in the background when you have
00:13:06.560 00:13:06.570 intimidations it seems that our and you
00:13:09.500 00:13:09.510 know stamina cooling in the top of that
00:13:12.860 00:13:12.870 all and UV system always happen during
00:13:16.250 00:13:16.260 during water yeah using water in it
00:13:20.580 00:13:20.590 we prove the school receiving
00:13:25.050 00:13:25.060 hydrocarbons like pulling a hydrocarbon
00:13:27.360 00:13:27.370 gas or
00:13:28.700 00:13:28.710 oh yes yeah yeah do a propane condenser
00:13:32.940 00:13:32.950 propylene condensers you know we can we
00:13:37.260 00:13:37.270 be cool just about everything we say
00:13:38.970 00:13:38.980 from jet fuel to to water so as long as
00:13:42.930 00:13:42.940 we know what the chemical composition of
00:13:45.329 00:13:45.339 the stream we can design to that
00:13:48.590 00:13:48.600 depending on the composition of the
00:13:51.030 00:13:51.040 stream like the hydrogen sulfide for
00:13:53.610 00:13:53.620 example you may want to use more exotic
00:13:56.010 00:13:56.020 metals for the process what it
00:13:58.800 00:13:58.810 components but yeah we know other guest
00:14:01.740 00:14:01.750 market we never a several hydrocarbon
00:14:04.350 00:14:04.360 mom coolers or condensers and just
00:14:08.220 00:14:08.230 another small basic you have to build a
00:14:11.190 00:14:11.200 small cooling power with this the
00:14:16.730 00:14:16.740 technology or a paint a advantage of
00:14:19.650 00:14:19.660 bleep out of it already exist in the
00:14:21.840 00:14:21.850 refinery the one-step reserve border you
00:14:24.690 00:14:24.700 can think of it like that animation
00:14:26.340 00:14:26.350 showed is a combination shell into the
00:14:29.220 00:14:29.230 end point out so you don't need another
00:14:32.040 00:14:32.050 point sour with the web surface and I'm
00:14:36.360 00:14:36.370 sorry was the second part again then as
00:14:38.970 00:14:38.980 may be hope you can't take advantage of
00:14:42.450 00:14:42.460 including our very existence make
00:14:45.930 00:14:45.940 Internet makes littering the design is
00:14:50.040 00:14:50.050 already recruited the it's helpful our
00:14:53.010 00:14:53.020 and we don't really compete against
00:14:56.040 00:14:56.050 other what surface air coolers but we're
00:14:58.290 00:14:58.300 working against this other technologies
00:15:00.030 00:15:00.040 so the wet surface air cooler would
00:15:03.210 00:15:03.220 replace a combination cooling tower and
00:15:06.600 00:15:06.610 ehe
00:15:07.620 00:15:07.630 so instead of the coin tower and the
00:15:10.320 00:15:10.330 exchanger you would use a web service
00:15:13.079 00:15:13.089 Airport in existing plants where maybe
00:15:16.199 00:15:16.209 you are limited with fresh water sources
00:15:19.590 00:15:19.600 but you have to increase the g-load um I
00:15:23.579 00:15:23.589 don't know if I mentioned this I should
00:15:25.440 00:15:25.450 that we can use poor water quality as
00:15:28.110 00:15:28.120 made up to the wet surface so it
00:15:32.210 00:15:32.220 one application Middle East we use the
00:15:34.760 00:15:34.770 red seat as maked water to the rough
00:15:37.280 00:15:37.290 surface but all the times you can take
00:15:39.530 00:15:39.540 holy tire blow down on our Oh reject
00:15:42.820 00:15:42.830 that and be used as makeup water to the
00:15:46.340 00:15:46.350 wet surface air cooler
00:16:04.390 00:16:04.400
