  • the natural gasoline component preferably contains hydrocarbons having from about 4 to about 12 carbons. Most preferably, the natural gasoline component contains at least 60 volume percent of 5 and 6 carbon hydrocarbons and at least 20 volume percent of hydrocarbons having 7 or more carbons.
  • the octane-enhancing component can be selected from several suitable compounds, and can also include mixtures of compounds.
  • the octane-enhancing components will preferably have a high octane rating with an (R+M)/2 octane of greater than about 85.
  • the octane-enhancing components should preferably also have a low vapor pressure, with a Reid vapor pressure of less than about 8 psia, and most preferably of about 1 psia or less.
  • Toluene alone or in combination with other octane-enhancing components, is a presently preferred octane-enhancing component.
  • the toluene component should be relatively pure, although up to about 10 volume percent of the toluene component can be other aromatics having six to nine carbon atoms.
  • octane- enhancing components include methyl tertiary butyl ether; ethylbenzene; m-xylene; p-xylene; o-xylene; eight carbon aromatic mixtures; nine carbon aromatic mixtures; cumene (isopropylbenzene) ; n-propylbenzene; alkylates (isoparaffins) ; catalytic cracked naphtha; catalytic reformate; and pyrolysis gasoline.
  • the octane-enhancing components are added and mixed with the natural gasoline component.
  • a vapor stream of light-weight hydrocarbons is withdrawn from the natural gasoline, before and/or after blending with the octane-enhancing component.
  • the natural gasoline mixture is agitated or otherwise caused to form particles or droplets tc increase the surface area of the liquid and to facilitate the release of light-weight hydrocarbons from the liquid.
  • the light-weight hydrocarbons which are released from the liquid blend can be burned to generate energy to power the pumps and to provide for the other energy requirements of the process. Alternatively, these light-weight hydrocarbons can be stored for later use.
  • the weathering process preferably continues for about 8-12 hours to allow for thorough mixing of the components and a reduction in the amount of light-weight hydrocarbons in the mixture.
  • the resulting product normally will be a liquid fuel with about 30-80 volume percent natural gasoline, about 20-50 volume percent octane-enhancing components, and may also contain about 0- 35 volume percent low-weight hydrocarbons.
  • the proportions of the components can be adjusted to vary the octane rating and vapor pressure of the product gasoline.
  • Fig. 1 is a schematic view of a process and apparatus according to the invention, partially broken away for clarity.
  • Fig. 2 is a cross-section taken along line 2-2 in Fig. 1.

Most of the methane, together with ethane, propane, and some butanes, exit from the process with only the natural gasoline being condensed and collected by suitable methods known in the art, including cascade refrigeration extraction processes. These methane rich streams, free of natural gasoline components, are used principally as a fuel in homes and in power generating stations. Excess low-weight hydrocarbons can be sold separately.

  • a low-weight hydrocarbon component can be added to the natural gasoline component and the octane-enhancing component in order to more economically produce a merchantable gasoline having a sufficiently low Reid vapor pressure and a satisfactory octane rating. This will depend on current commodity prices.

  • the natural gasoline component with the low-weight hydrocarbon component. It is anticipated that approximately 1-3 volume percent light-weight hydrocarbons will be weathered off in the process. These will include methane, ethane, propane and some butane. These light- weight hydrocarbons are weathered off during the blending operation, and can be combusted to generate power and to run pumps used in blending. Excess vapor can be stored by suitable means such as underground storage wells or compressed-gas vessels.
  • the components can be mixed together thoroughly by suitable mixing apparatus, and the mixture is caused to attain a liquid form having an extended surface area, such as droplets or a film-like surface area. This has been found to facilitate the release of light-weight hydrocarbons from the liquid.
  • a vapor stream is withdrawn to remove these light-weight hydrocarbons including methanes, ethanes, propanes and some butanes.

Agitation will blend the components and will cause the formation of droplets or a film-like surface area on the side of a vertical vessel, such that the liquid will have an increased surface area relative to the bulk liquid.
  • the extended surface area facilitates the release of light-weight hydrocarbon vapors from the liquid.
  • An enclosure formed as a tower will also provide for a stripping action, which action can also be useful to facilitate the removal of light-weight hydrocarbons and to minimize the escape of higher-weight hydrocarbons. Vapor flows upward to a vapor space and liquid flows downward to a liquid space of the enclosure. The vapor stream is withdrawn from the vapor space. The contact of the rising vapors with the falling liquid will help to retain heavier hydrocarbons in the falling liquid.

  • Other known methods for increasing the surface area of liquids such as passing the liquid through a packed column or over plates in a column, are also possible. These structures will also act to blend the liquid components together. It might also be possible to facilitate the removal of light-weight hydrocarbons by the introduction of a stripping gas, or by the application of heat. It is a feature of the invention, however, that the natural gasoline can be successfully processed in a substantially isothermal process, without the introduction of heat.

  • the condensing or coalescing apparatus can be of any suitable design, but preferably has a large amount of condensing or coalescing surface area such as would be provided by conventional tower packing material.
  • a ceramic packing is presently preferred, although other materials, including platinum, could also be useful.
  • the removal of light-weight hydrocarbons from the natural gasoline component can occur before and/or after the introduction of the octane-enhancing components. It is presently preferred that at least some removal of light-weight hydrocarbons according to the invention occur after the introduction of the octane-enhancing components. It is possible to mix the natural gasoline component with the octane-enhancing component in a separate operation, however, a thorough mixing will usually result from the agitation or other process used to remove the light-weight hydrocarbons from the natural gasoline.
  • a presently preferred mixing apparatus is shown in Figs. 1-2.
  • a number of storage tanks 10-13 can be provided, although more or fewer storage tanks can be provided if desired.

  • Liquid hydrocarbons coalesced or condensed in the coalescing or condenser apparatus 44 can fall under the influence of gravity into the vapor manifold 36 and return to the storage tanks 10-13 through the vapor return paths 38-41.
  • Alternative coalescing or condensing operations are also possible to coalesce or condense low-weight hydrocarbons from the light ⁇ weight hydrocarbon vapors.
  • the vapors leaving the coalescing or condenser apparatus 44 through the coalescing or condenser outlet 50 will consist primarily of light-weight hydrocarbons such as methanes, ethanes, propanes and some butanes.

Abstract

Des essences mélangées sont produites en mélangeant un composant d'essence naturelle et au moins un composant augmentant l'indice d'octanes. Le mélange est soumis à l'action de l'air pendant l'opération de mélange pour éliminer les hydrocarbures légers comprenant des composants comportant un à quatre carbones. Ces hydrocarbures légers qui, de préférence, constituent moins de 3 % de l'essence mélangée, peuvent être récupérés pour générer du courant destiné au fonctionnement du procédé. Le mélange d'essence liquide est formulé de façon à produire un indice d'octanes souhaité, une pression de vapeur acceptable pour l'environnement et un mélange qui, lorsqu'il est brûlé dans un moteur à combustion interne, produit une quantité minimale de polluants.
