Definitions

  • the present invention relates to the stripping of the oil produced in the middle stage of the main separation tower of oil refining and petrochemical plant, and more specifically, in the RFCC process, the product of the middle stage of the separation column is hardened by the partial pressure of nitrogen injected into the stripper. It relates to a method for removing oil and water.
  • Residue Fluid Catalyst Cracking is a process that produces gasoline feedstock through fluidized bed catalytic cracking from low sulfur fuel oil and low sulfur atmospheric pressure residue produced in heavy oil desulfurization.
  • the middle stage of the main separation tower of the FCC process produces the oil necessary for the blending of kerosene, diesel, etc., which is commonly referred to as a side cut.
  • the components of the sidecut fractions mainly include HCN and LCO fractions.
  • HCN heavy catalytic naphtha
  • LCO light cycle oil
  • Auxiliary separation towers for this purpose were a type using a reboiler, a vacuum stripping type, and a steam stripping type.
  • a side cut is introduced into the steam using separator 110 through a side cut introduction pipe 115 at an intermediate end of the main separator 100, and injected through the steam injection unit 115. Separation takes place by steam. Thereafter, the separated oil is introduced into the additional water separator 120 along the pipe 3 (119), and the separated water is discharged along the water discharge pipe 121 and the oil is removed from the water pipe 4 (123). Go through
  • U.S. Patent No. 4,606,816 and the like also disclose inventions related to the distillation of crude oil or separation using steam in auxiliary separators, and do not suggest ways to increase or improve the effects thereof.
  • the vacuum stripping type requires a lot of equipment, such as a vacuum equipment, a condenser, a receiver, a pump, etc., and thus has a problem of high cost.
  • the object of the present invention was to find that nitrogen is preferred as a suitable gas used to separate the products of the middle stage of the main separation tower in the auxiliary separator in the above FCC process, and in case of using nitrogen, To solve the problem and at the same time provide a way to lower the water to less than saturated water.
  • HCN and LCO having a boiling point of 180 ° C to 360 ° C is separated from the main separation column and then mixed with nitrogen gas before being mixed into the diesel product.
  • Another embodiment of the present invention is to provide an auxiliary separator using the method in an FCC process.
  • the present invention in comparison with the conventional method, there is no additional equipment other than the auxiliary separator, which is advantageous in terms of cost, and the above-mentioned effect is achieved only by connecting the nitrogen injection pipe when applied to the existing conventional auxiliary separator.
  • the advantage is that it is possible.
  • it is possible to reduce the moisture to below the saturation level at the same time as meeting the flash point specification in terms of efficiency, and solve the appearance problem fundamentally.
  • the oil can be directly blended into kerosene and diesel products.
  • FIG 1 shows that the steam stripper is used in the conventional FCC process.
  • Figure 2 shows a stripper using nitrogen in the FCC process.
  • main separator 105 side cut introduction tube
  • the side-cut oil produced at the intermediate stage of the main separator 100 is introduced into the nitrogen-using stripper 200 along the side-cut introduction tube 105.
  • Nitrogen is introduced into the nitrogen utilization stripper 200 along the nitrogen injection unit 201.
  • the injection pressure of nitrogen should be set higher than the stripper pressure so that nitrogen can be injected into the stripper sufficiently.
  • the pressure of the stripper may vary in each case, but is obvious to those skilled in the art. Nitrogen is then injected into the separator at the same point as the pressure inside the separator.
  • the injection amount of nitrogen ranges from 0.1 kgmole / m 3 (oil) to 0.4 kgmole / m 3 (oil), preferably 0.2 kgmole / m 3 (oil) to 0.3 kgmole / m 3 (oil).
  • the injection amount of nitrogen is less than 0.1 kgmole / m 3 (oil)
  • the nitrogen is excessive to the nitrogen
  • the light oil and water removed in the separator are returned back to the main separation column through pipe 2 (203).
  • the hard oil and the oil removed from the separator are sent to the storage tank along the pipe 1 (205).
  • the domestic diesel products usually have a flash point of 40 °C or more
  • the oil separated from the stripper has a flash point of 60 to 68 °C.
  • the appearance also satisfies B & C (Bright & Clear).
  • the appearance standard is judged by the naked eye, and is determined by selecting the most similar standard picture by comparing light with a standard sample by transmitting light through a transparent sample bottle. Standard photographs here are well known in the art and are classified into six grades: Bright & Clear, Slight Hazy, Hazy, Free Water, Sediment, and Suspended Solid.
  • the oil separated in the separator can be used for blending in kerosene and diesel products without additional water removal, unlike steam.
  • Table 1 compares the results of Example 1 with the state before stripping with nitrogen.
  • Example 2 The same implementation as in Example 1 was repeated except that the amount of nitrogen used was changed to 0.15 kgmole / m 3 (oil).
  • Example 2 The same run as in Example 1 was repeated except that 0.28 kgmole / m 3 (oil) of steam was used instead of nitrogen for the stripper.
  • Example 1 The results of Example 1 and Comparative Example 1 are shown in the following table.
  • the flash point was formed in a similar range, but it can be seen that the moisture content when using nitrogen is much smaller than using steam.
  • B & C is satisfied when nitrogen is used as compared to hazy.
  • the use of nitrogen does not require the addition of a water removal process additionally required in the use of steam, and also an additional process for satisfying the appearance is not required.
  • Example 1 was repeated in the same manner except that the nitrogen injection amount was 0.1 kgmole / m 3 (oil).
  • Example 1 was repeated in the same manner except that no nitrogen was injected.
