Definitions

  • the present invention relates to a field of a chemical industry equipment and a chemical industry method, and in particular to a heat exchange device for atmospheric tower oil-gas and a heat exchange method thereof.
  • an atmospheric and vacuum distillation unit divides the crude oil into naphtha, aviation kerosene, diesel, kerosene, vacuum residues and other fractions by distillation.
  • the technical distillation level and the stable and efficient operation of this unit are directly relevant to the yield and economical benefits of the subsequent units.
  • the overall quality of the crude oil around the world declines, including declined global yield of light crude oil, rising sulfur content, aggregated oleic performance, and increased exploration difficulty, there is thus a large amount of Cl-containing auxiliaries in the processed crude oil.
  • the units are generally constructed in such a manner that the corrosion is relieved by upgrading materials and enhancing corrosion-resistant measurements "one removal and three injections". Nevertheless, the corrosion and leakage of the atmospheric tower top heat exchanger are still very serious.
  • Most atmospheric tower top heat exchangers are common heat exchangers. Although the grade of materials has been improved because of the anti-corrosion requirements, majority of such atmospheric tower top heat exchangers are still unable to operate for a long period, and tube bundles are likely to be corroded to result in leakage.
  • Some of the atmospheric tower top heat exchangers are welded-plate heat exchangers. Although the materials of such heat exchanges are upgraded, it is likely to result in channel occlusion and leakage due to their poor fluctuation resistance and small circulation channel.
  • a first technical problem to be solved by the present invention is, in view of the prior art, to provide an heat exchange device for atmospheric tower oil-gas which can effectively avoid the occlusion of the heat exchanger so as to achieve the purpose of preventing the equipment from corrosion, prolonging the operating period and reducing the operating cost.
  • a second technical problem to be solved by the present invention is to provide an atmospheric tower oil-gas heat exchange method which can effectively avoid the occlusion of the heat exchanger.
  • the heat exchange device for atmospheric tower oil-gas comprises, a heat exchanger, the heat exchanger comprising a shell having a top, a bottom, a tube pass entrance and a tube pass exit; an upper tube plate and a lower tube plate which both are located within the shell; and supported between the upper tube plate and a lower tube plate; an inlet of each heat exchange tube connecting to a tube pass entrance arranged on the bottom of the shell, while an outlet of each heat exchange tube connecting to a tube pass exit arranged on the top of the shell, the tube pass exit and the tube pass entrance used for connecting crude oil flow; a shell pass entrance for connecting to an atmospheric tower oil-gas pipeline arranged on an upper portion of the shell; and a shell pass exit arranged on a lower portion of the shell; characterized in that:
  • annular water injection pipe connected to an external water injection pipeline is arranged within the upper portion of the shell, the annular water injection pipe has multiple water pores communicated to the interior of the shell;
  • the atmospheric tower oil-gas pipeline is connected to the external water injection pipeline via a first water injection pipeline and a third water injection pipeline;
  • a first solenoid valve and a second solenoid valve are respectively arranged on the first water injection pipeline and the third water injection pipeline; and, the annular water injection pipe is communicated to the external water injection pipeline via a second water injection pipeline.
  • the shell has a water inlet, and the external water injection pipeline is communicated to the annular water injection pipe via the water inlet.
  • the annular water injection pipe is located below the upper tube plate and close to the upper tube plate.
  • each heat exchange tube between the upper tube plate and the lower tube plate is coiled around a central axis of the shell.
  • a gas outlet which is communicated to the interior of the shell and used for exhausting gas on the top of the shell during maintenance, is further arranged on the top of the shell, and a liquid outlet for discharging liquid on the bottom of the shell during maintenance is further arranged on the bottom of the shell.
  • each of the heat exchange tubes is a pure-titanium heat exchange tube.
  • the heat exchange method using the heat exchange device for atmospheric tower oil-gas provided in the above solutions comprises the following steps:
  • the heat exchange device for atmospheric tower oil-gas and heat exchange method of the present invention under feeding water to the oil-gas pipeline and washing the shell by the annular water injection pipe, the heat exchange efficiency is effectively improved, the anti-fouling performance is excellent and the resistance against HCl-H 2 S-H 2 O corrosion and under-deposit corrosion is great. Moreover, the stubborn phenomena such as corrosion resulted from ammonium salt crystalline deposit and occlusion resulted from ferrous sulfide are avoided, and the problems of frequent occlusion and leakage or even replacement of the atmospheric tower oil-gas/crude oil head exchanger due to its easy corrosion, leakage, channel occlusion or other factors are solved. Meanwhile, the device has a small pressure drop and a stable operation, so that the safe operating period of the device is greatly increased.
  • the heat exchange device for atmospheric tower oil-gas comprises:
  • An upper tube plate 16 and a lower tube plate 17 are further provided inside the shell 11.
  • each heat exchange tube 5 is a pure-titanium heat exchange tube for ensuring the anti-corrosion performance of the heat exchange tubes.
  • Upper and lower ends of each of the heat exchange tubes are fixed on the upper tube plate and the lower tube plate respectively.
  • a portion of each heat exchange tubes between the upper tube plate 16 and the lower tube plate 17 is coiled around a central axis of the shell 11 in order to improve the heat exchange efficiency.
  • An annular water injection pipe 6 is provided inside the shell 11 and located close to the upper tube plate 16 and below the upper tube plate 16. Multiple water pores 61 communicated to the interior of the shell are uniformly distributed on the wall of the annular water injection pipe 6. An inlet of the annular water injection pipe 6 is connected to a second water injection pipeline 32 via the water inlet 15.
  • a shell pass entrance 12 is connected to an atmospheric tower oil-gas pipeline 2, a first water injection pipeline 31 and a third water injection pipeline 33 are connected onto the atmospheric tower oil-gas pipeline 2, and both the first water injection pipeline 31 and the third water injection pipeline 33 are connected to an external water injection pipeline 3; and a first solenoid valve 34 and a second solenoid valve 35 are respectively arranged on the first water injection pipeline 31 and the third water injection pipeline 33.
  • Water is fed into the atmospheric tower oil-gas pipeline 2 via the first water injection pipeline 31.
  • the solenoid valves are used for adjusting the water flow.
  • the third water injection pipeline is used for intermittently injecting water into the atmospheric tower oil-gas pipeline 2 for purpose of washing the shell pass at a large water flow.
  • Both the first water injection pipeline 31 and the third water injection pipeline 33 are connected to the external water injection pipeline 3, and solenoid valves are respectively provided on the first water injection pipeline 31 and the third water injection pipeline 33.
  • the two solenoid valves are connected to a control system (not shown in the Figs). The ON, OFF and degree of opening of the two solenoid valves are controlled by the control system, so that the water injection by each water injection pipeline is controlled.
  • a heat exchange method using the atmospheric tower oil-gas head exchange device described above comprising the following steps:
  • the atmospheric tower oil-gas has a flow of 43860 kg/h, a temperature of 125°C, a pressure of 0.11 MPaG, and a temperature of 82°C at the outlet after the heat exchange;
  • the first stream of injected water has a flow of 1000 kg/h and a temperature of 40°C;
  • the crude oil has a flow of 192400 kg/h, a temperature of 32°C at the inlet, a pressure of 2.1 MPaG, and a temperature of 72°C at the outlet after the heat exchange;
  • the gas outlet 10 is opened to exhaust atmospheric tower oil-gas gathered in the upper portion of the shell.
  • the equipment is disassembled and then washed. Cleaning liquid is injected from the gas outlet 10 and drained from the liquid outlet 19.
  • the service life of an existing common atmospheric tower top heat exhauster is about 1 to 2 years, and the whole existing common atmospheric tower top heat exhauster or the whole tube bundle needs to be replaced when corrosion and leakage occur.
  • the existing common atmospheric tower top heat exchanger needs to be frequently cleaned due to channel occlusion.
  • the equipment body has excellent corrosion resistance and anti-fouling performance, and within two operating periods (i.e., 8 years), no fouling (thus occlusion) and corrosion (thus leakage) occurs. Therefore, a large amount of cost for equipment replacement and maintenance is saved.
