00:00:00.060 --> 00:00:06.120 The refinery process when you have completed the section you should be 00:00:06.120 --> 00:00:28.640 familiar with simple refining semi complex refining complex refining 00:00:35.290 --> 00:00:41.510 in this section the refining of residual fuel oils will be described the 00:00:41.510 --> 00:00:47.710 particular emphasis on the origin of both residual and Dilli whant components 00:00:47.710 --> 00:00:53.780 we will begin by briefly describing the configuration of Noida finally and 00:00:53.780 --> 00:01:01.300 highlight the main process units to utilize fully the potential of crude oil 00:01:01.300 --> 00:01:07.899 it is necessary to separate this constituents into a number of fractions 00:01:07.899 --> 00:01:14.920 this is the objective of oil refining refinery's can be divided into three 00:01:14.920 --> 00:01:17.790 different categories 00:01:57.580 --> 00:02:01.030 simple refinement 00:02:01.030 --> 00:02:07.470 the foundation of the refinery is the atmospheric distillation unit 00:03:43.310 --> 00:03:50.549 the fractions obtained through atmospheric distillation are gases such 00:03:50.549 --> 00:03:54.470 as ethane propane butane 00:03:55.250 --> 00:04:07.210 light distillates such as gasoline NAFTA chemical feedstocks kerosene for 00:04:07.210 --> 00:04:16.100 domestic and aviation fuel gas oils for diesel engines domestic and industrial 00:04:16.100 --> 00:04:19.389 use 00:04:19.389 --> 00:04:30.539 long residue for fewer lawyers loves feedstocks waxes bitumen conversion 00:04:33.689 --> 00:04:40.330 simple refining is also called primary refining and are used for physical 00:04:40.330 --> 00:04:47.259 separation of different crude oil fractions separation pressure is 00:04:47.259 --> 00:04:56.259 atmospheric the separation temperature is below 350 degrees Celsius semi 00:04:56.259 --> 00:05:01.040 complex refining 00:06:25.040 --> 00:06:30.930 the semi complex refining process is characterized by the thermal gas oil 00:06:30.930 --> 00:06:36.200 unit which is similar to this breaking 00:06:36.270 --> 00:06:43.110 residue from the first stage is vacuum flashed heavy distillate from the first 00:06:43.110 --> 00:06:50.039 stage is cracked in a second furnace at a temperature 500 degrees Celsius and a 00:06:50.039 --> 00:07:00.169 pressure of 20 to 25 bar viscosity of the residue varies 00:07:02.790 --> 00:07:09.210 a complex refinery uses a combination of physical separation and chemical 00:07:09.210 --> 00:07:13.810 conversion processes 00:09:13.100 --> 00:09:31.039 hydro treatment is used to reduce the sulfur content 00:11:52.540 --> 00:11:57.190 simply refinery long residue from the atmospheric 00:11:57.190 --> 00:12:07.750 distillation unit is diluted with gas oil semi complex refinery the fuel oil 00:12:07.750 --> 00:12:13.660 would generally comprised residue from the thermal gas soil unit debuted with 00:12:13.660 --> 00:12:19.990 thermally cracked gas oil generally some residue and diluents from the 00:12:19.990 --> 00:12:29.680 atmospheric distiller will also be incorporated complex refineries a fully 00:12:29.680 --> 00:12:35.139 complex refinery include all the processes there's a wide range of 00:12:35.139 --> 00:12:51.190 residues and diluents are available
