    • C10G7/00—Distillation of hydrocarbon oils

Definitions

  • the invention has a device for continuous distillation Separation of crude oil with a distillation tower for Object.
  • standing cylinder furnaces which provided a vertical cylindrical combustion chamber is surrounded by standing tubes arranged in a circle is. At the bottom of the cylinder furnace are the burning nozzles for one Gas heating arranged, whereas in the upper area Radiation cone is provided for uniform heat transfer care of the gases on the tube bundle.
  • the aim of the present invention is a device with low equipment expenditure for continuous distillation To process crude oil, in which the crude oil particularly gentle continuously and evenly with different heat requirements except for temperatures between 350 ° C and 400 ° C can be heated, while electrical Energy gained and the waste heat of a high quality Can be used.
  • the device according to the invention for continuous distillation Separation of crude oil, at least through a pipeline a, in particular gas-heated, furnace can be fed, which via a pipeline directly or indirectly with the evaporation zone a distillation tower with shelves, especially bell bottoms, is connected with strippers, which with at least two different shelves and with a steam generator and / or superheater are connected and a head cooler, is essentially that in addition a gas turbine connected to a power generator is provided with an exhaust gas heat exchanger for the crude oil, through which the crude oil can be heated directly and / or indirectly, the exhaust gas heat exchanger and / or another Heat exchanger is connected in series with the furnace.
  • a furnace is provided in addition to the gas turbine, can do the distillative separation during maintenance work on the gas turbine of the crude oil continue to be carried out by Control of the heating power of the furnace of different heat requirements covered and thus a uniform performance of the gas turbine can be ensured.
  • the gas turbine GT shown in FIG. 1 with a speed of 3,000 or 3,600 rpm is mechanically coupled to the power generator G.
  • the gas turbine has a consumption of 7,500 m 3 / h natural gas. It is an aeroderiative turbine, e.g. B. LM 2500+ General Electric or DLE 2.500+ General Electric with lower nitrogen oxide emissions.
  • the generator delivers 30,000 kW.
  • the gases emerging from the gas turbine with a temperature of 510 ° C. enter an additional firing NB, in which the remaining oxygen content is burned with additionally introduced natural gas (arrow a).
  • the gases emerging from the additional firing have a temperature of 700 ° C.
  • the exhaust gases give their heat to a heat transfer fluid, u.
  • the heat transfer fluid in line w connects the exhaust gas heat exchanger W 1 to a further heat exchanger W 2 .
  • crude oil at 140 ° C. is introduced via line L 1 and passes through line L 2 at 250 ° C. into gas furnace 1, 2, in which it is additionally heated to 370 ° C.
  • the further heat exchanger W 2 and the furnace 1, 2 are connected in series.
  • the line w can also lead to a steam generator D, in which steam is generated for the stripping process.
  • the exhaust gases are passed from the heat exchanger W 1 into a heat exchanger W 3 , in which water is heated for district heating.
  • the exhaust gases from the gas furnace 1, 2 are cooled via a heat exchanger W 4 and the heat is used for process steam within the refinery.
  • the temperature of the exhaust gases is kept above 100 ° C so that no condensation occurs in the chimney.
  • the crude oil heated to 370 ° C. is fed to the distillation tower via line L 3 .
  • a temperature sensor T 1 is arranged, which controls the flow of a valve V 1 for the gas of the furnace 1, 2 but also the fuel supply, arrow a, regulates additional firing NB.
  • a further temperature sensor T 2 is arranged, which in turn takes care of regulating and controlling the flow rate of the valve V 2 , which also allows the amount of gas supplied to the furnace but also the fuel supply for the additional firing and thus the heating power to be regulated and controlled ,
  • the crude oil arrives from furnaces 1 and 2 in line L 3 into stripping column 3, into which steam is introduced according to arrow X 1 .
  • a part of the bottom product also enters the stripper column 3 (arrow L) from the bottom of the distillation tower 4.
  • the crude oil, which is introduced via line L 3 was heated to 370 ° C. by means of the waste heat from the gas turbine and the furnaces 1, 2.
  • the stripping column 3 the crude oil is expanded from 5 bar to 3 bar and is then passed along the line X 2 into the evaporation zone of the distillation tower 4. A further relaxation to 1.5 bar occurs in this. 45 bubble trays are arranged in the distillation tower 4.
  • the products withdrawn from the distillation tower are introduced, steam is applied to them via lines D 1 , D 2 , D 3 and the more volatile constituents are thus expelled.
  • the material to be recovered is drawn off in the bottom of the strippers, whereas the top product is fed back to the column.
  • the steam which is used in the strippers was obtained with the exhaust gas heat from the gas turbine in the steam generator D (FIG. 1).
  • the end product drawn off from the strippers is cooled by heat exchangers W 5 , W 6 , W 7 and the heat thus obtained is recovered.
  • the distillation tower 4 also has a head cooler 8.
