Definitions

  • My present invention relates to improvements in methods in and apparatus for converting hydrocarbon oils, particularly for the purpose of producing motor fuels of the gasoline typ
  • hydrocarbon material as, for example, petroleum oil
  • a neutral, non-condensible heat-carrier gas which has been raised to a suitable temperature, as by means of a heater of the regenerative type.
  • the carrier gas, admixed with the vapor products is then passed from the reaction chamber and led to a scrubbing chamber wherein it is contacted with oil which washes out the carbon contained in the gas and vapor products.
  • This oil preferably is constituted in part by the charging stock.
  • the carrier gas after being stripped of residual vapors may be divided into a portion which is led out of the system, and a portion which is led back into the system and suitably heated by available heat therein.
  • the gas is then admixed to the regenerative heater to recommence another cycle.
  • the presence of a large volume of gas in the scrubber greatly facilitates the vaporization of the oil therein, and in the present invention this effect is relied upon to vaporize all the fractions in the charging stock which it is desired to convert.
  • the present invention seeks to provide for maintaining the proper balance between the amount of carrier gas needed to convert the oil, and that which is subsequently required to vaporize the desired components of the charging stock.
  • heater I3 gas from pipe ill from a source to be described is admitted to heater I3 which is conveniently of the hot blast stove type.
  • This heater has, previous to the admission of the gas, been-fired with fuel from a source (not shown) until it is at the requisite temperature e. g. 1500 to 1800 F., during which operation the products of combustion are led out through a pipe I! and up a stack ll.
  • the combustion is stopped, the stove purged of combustion gases, and the heat-yielding cycle begun by admitting carrier gas through pipe Ill.
  • the gas passes through the stove and is thereby heated and leaves same through a pipe is and passes to reaction chamber 2
  • a bypass 23 from pipe Ill to pipe l9 provides for the admission to pipe IQ of a regulated supply of the unheated gas for the purpose of maintaining the temperature of the gas in pipe 19 substantially constant.
  • Oil vapor to be converted is admitted to reaction chamber 2
  • the converted products including the carrier gas, then leave the chamber through pipe 33 and pass thence into scrubber 35.
  • the products are washed with oil from tank 31 constituting in part, at least, the charging stock, in which operation the gas and vapor products are thoughly scrubbed and are deprived of their carbon and a portion of their heat content.
  • the unvaporized scrubbing oil leaves the scrubber through a pipe 39, whence it is passed to suitable heat exchange devices not necessary to describe herein whereupon a portion thereof is removed from the system as residue, and a further portion returned to tank 31 by piping not shown. 1
  • the scrubbed products leave the scrubber 35 through pipe I and are admitted to a rectifier 43 wherein the fractionssuitable for cracking are dropped out and leave through pipe 25, above mentioned.
  • the products 'uncondensed from rectifler 43 leave through a, pipe I! and pass to a condenser 41 wherein the desired products of the system, such as motor fuel, are dropped out and collected in accumulator 49.
  • the carrier gas leaves the accumulator through pipe II and may be passed therefrom through pipe 53 and pump 65 to an absorber 51 wherein the residual vapors are stripped from the gas by means well understood in. the art.
  • the stripped gas then' passes through pipe 59 to a heat exchanger ll through which may be circulated the hot scrubbing liquid from scrubber 35 by means of piping,-
  • the carrier gas preferably at a temperature of 500 F. leaves the heat exchanger 6
  • This pipe whlchadmits the desired excess carrier gas to the scrubber, preferably has three branches 61, 69, ll, so that the gas can be admitted either to the bottom of the reaction chamber through pipe 61 or into pipe 33 connecting the reaction chamber with the scrubberr'o'r' through pipe ll joining the scrubber directly.
  • a by-pass 13 is provided around a heat exchanger 6
  • the effect of the added gas is to facilitate evaporation both by lowering the partialpressures on the components of the oil undergoing evaporation, and by furnishing additional heat. It will be evident, however, that the added gas will facilitate evaporation, even through its temperature may vary considerably. Accordingly, it will be seen that by the use of the supply of gas through pipe 65 conditions in the scrubber may be accurately controlled whereby complete vaporization may be effected of the fractions which it is desired to convert.
  • a reaction chamber a source of heatcarrier gas, means for admitting hydrocarbon compounds into said reaction chamber, there to be subjected to the action of the heat-carrier gas, a scrubbing chamber, means for leading off the gas and vapor products from said reaction chamber and admitting them directly to said scrubbing chamber, means for admitting charging stock to the scrubbing chamber, means for separating from said carrier gas the desired products of the conversion reaction, means for lead-' ing back to the system the residual carrier gas,
