1 00:00:07,620 --> 00:00:11,340 Welcome to the eProcess demonstration video on the desanding hydrocyclone. 2 00:00:11,490 --> 00:00:14,020 The apparatus shown is a two inch 3 00:00:14,023 --> 00:00:15,623 clear urethane. 4 00:00:15,820 --> 00:00:19,670 hydrocyclone connected to a clear 35 litre. 5 00:00:19,823 --> 00:00:23,823 accumulator section here at the bottom. 6 00:00:23,490 --> 00:00:26,530 Together they make a desanding hydrocyclone apparatus. 7 00:00:26,530 --> 00:00:29,320 In this apparatus will be flowing water 8 00:00:30,023 --> 00:00:32,623 and coal particles at 12 by 20 mesh. 9 00:00:32,923 --> 00:00:34,023 This is done just purely 10 00:00:34,223 --> 00:00:37,823 so you can visualize the movement of the coal particles. 11 00:00:38,523 --> 00:00:41,423 In this case, it takes about 75 seconds to fill the apparatus, which 12 00:00:41,423 --> 00:00:42,323 includes the accumulator 13 00:00:42,323 --> 00:00:44,523 and the hydrocyclone body. 14 00:00:45,023 --> 00:00:47,523 A few particles are added in this case, just to make sure that the 15 00:00:47,523 --> 00:00:50,323 flow is working properly and separation is occurring. 16 00:00:51,923 --> 00:00:57,423 Next, we will introduce particles at a steady state, low concentration 17 00:00:57,423 --> 00:01:00,623 of solids. Steady state, meaning particles, are being introduced 18 00:01:00,723 --> 00:01:05,323 separated 100% separation efficiency. Reporting down through the apex 19 00:01:05,319 --> 00:01:09,300 and into the accumulation section. As a particles fall from the apex 20 00:01:09,720 --> 00:01:12,160 by gravity through the accumulator. 21 00:01:11,980 --> 00:01:15,520 Water is displaced from the accumulator back up through the hydrocyclone 22 00:01:15,523 --> 00:01:16,323 body itself. 23 00:01:16,920 --> 00:01:24,150 We are having 100% separation efficiency as mentioned, and shows the normal operation of a desanding hydrocyclone 24 00:01:24,290 --> 00:01:28,920 in case of like treatment separating, solids are sand from produced water. 25 00:01:30,523 --> 00:01:33,723 Next, we'll demonstrate the Apex flux line, which connects the 26 00:01:33,723 --> 00:01:38,223 accumulator to the overflow of the desander or hydrocyclone line 27 00:01:38,223 --> 00:01:42,623 itself. Allowing water to discharge from the accumulator instead of 28 00:01:42,623 --> 00:01:45,923 back up through the desander to the overflow line itself. 29 00:01:49,923 --> 00:01:52,623 Introducing solids at high concentration demonstrates. 30 00:01:52,623 --> 00:01:56,170 the effect of this apex flux line even more. High concentration solids 31 00:01:56,340 --> 00:01:59,600 will overload or overwhelm the hydrocyclone body 32 00:01:59,600 --> 00:02:06,123 Solids still being separated, but they are limited how fast they can pass through the apex 33 00:02:06,123 --> 00:02:09,023 And that's they will back up into, in the desander body or the 34 00:02:09,023 --> 00:02:12,523 hydrocyclone body, thus, eventually reporting to the overflow and 35 00:02:12,523 --> 00:02:19,223 having zero having low separation efficiency. An apex flux line opened now 36 00:02:19,223 --> 00:02:21,523 Removes that limit and allows the solids to come down quicker. 37 00:02:22,983 --> 00:02:25,523 Leaving that equalization line or the apex flux line open 38 00:02:25,523 --> 00:02:30,523 we can introduce a high concentration of solids at a continuous rate 39 00:02:31,023 --> 00:02:35,023 and you can see the stream line flow pattern of the solids within the 40 00:02:35,023 --> 00:02:36,123 hydrocyclone body. 41 00:02:36,523 --> 00:02:38,723 You see, the typical Cyclone Vortex flow. 42 00:02:39,223 --> 00:02:42,123 Solid particles are being introduced their passing down from the 43 00:02:42,123 --> 00:02:46,423 cyclone body under separating again, 100% efficiency down through the 44 00:02:46,423 --> 00:02:48,823 apex, into the accumulation chamber itself, 45 00:02:48,923 --> 00:02:51,223 falling very rapidly. 46 00:02:52,023 --> 00:02:54,823 And the apex flux line, allows that water to be discharged or removed 47 00:02:54,823 --> 00:02:55,823 from the apex flux. 48 00:02:56,323 --> 00:02:59,523 apex area more rapidly.
