Definitions

  • the object of the present invention is the reduction of water- and natural gas consumption for the recovery of oil from oil sands.
  • the object is achieved by conversion of the oil in the presence of the sand, so that a major part of the oil can be separated from the sand in a vaporous form.
  • the combustible components left on or in the sand are burnt to supply the energy, that is necessary to heat the oil sand to the reaction temperature and to supply the energy for further work up systems.
  • the main problem in handling oil sands is its stickiness, which problem moreover increases with temperature.
  • This problem is overcome by dropping the cold tar sand on a fluidised hot sand bed, where cold oil sand and hot spent sand are mixed in a ratio such, that the mixing temperature is in the range of 80 - 550°C, preferably 300 - 500°C.
  • the mixture of fresh oil sand and hot spent sand is sent to a reaction zone with a fluidised bed, where the oil is partially evaporated, partially converted into lighter, vaporous material.
  • a fluidised bed where the oil is partially evaporated, partially converted into lighter, vaporous material.
  • more hot sand may be added to raise the temperature of the oil/sand mixture to the desired reactor entry temperature.
  • thermal cracking any type of conversion, that can be done in a fluidised bed, may be applied in this reaction zone.
  • thermal cracking and partial oxidation. If thermal cracking only is used, the bed temperature will drop below that of the mixture of oil sand and hot spent sand. By the injection of oxygen into the reaction zone, the temperature will obviously be increased.
  • the actual reactor bed temperature is likely to be in the range of 450 - 500°C to evaporate the largest possible part of the oil feed, while limiting syn gas reactions (see below) and coke formation.
  • Combustion is known to be feasible below the auto ignition temperature of the component concerned, by the action of free radicals.
  • thermal cracking at a given temperature is easier than it would be outside of a combustion zone; a consequence of the action of free radicals emitted by the combustion reactions.
  • the auto ignition temperature depends on the hydrocarbon composition.
  • the first reactions between hydrocarbons and oxygen are those, in which carbon is oxidised to monoxide under the release of hydrogen. This is because the reactions concerned are by far the fastest, compared to other reactions that compete for oxygen.
  • the weakest links in hydrocarbon structures are those around the middle of straight chain (paraffinic) molecules or straight chain molecular parts. It follows that with a modest oxygen supply, say one atom per heavy oil molecule, or in the order of 2% by weight on a heavy oil, a considerable cracking effect can be reached. Added to that is the effect of free radicals, that are generated during the oxidation, which promote the thermal cracking reactions.
  • the combined effect makes it possible to have an interesting thermal cracking process at a relatively low temperature.
  • the mild conditions reduce the coke forming tendency.
  • the resulting mixture contains about 1 part oil and 4.5 parts sand, by weight. If this mixture is heated to 500° by partial oxidation, assuming no evaporation of the feed, about 24% of the carbon in the feed is converted into monoxide. For this, the oxygen consumption is about 30% by weight on oil feed.
  • Carbon monoxide and hydrogen can amongst others react according to the Boudouard reaction, the water gas reaction and the methane reaction (respectively
  • the vaporous cracking products are separated from the sand using means and methods in use in oil refining, e.g. in catalytic cracking. If oxygen injection has been applied, the resulting syngas can be used as fuel gas or as feed to the manufacture of premium diesel oil or methanol, using one of the Fischer Tropsch processes.
  • the sand leaving the reaction zone carries the part of the feed oil that is neither evaporated nor converted, and the condensed products like coke.
  • This mixture is fed into a second reaction zone, also applying a fluidised bed, in which the combustibles remaining in and on the sand after conversion are burnt off by air.
  • a temperature level of 700°C is adopted. If the combustible content of the sand is more than what is necessary to heat the sand to 700°, a sand cooler may be used, similar to the catalyst cooler sometimes used in the regenerator of an oil catalytic cracking unit, already referred to above under 'partial oxidation'.
  • the net produced sand, after deduction of the hot spent sand recycle, is cooled and disposed of.
  • the quantity of oil left on the sand after partial removal might be low enough to omit the conversion process completely, and to feed the sand and remaining oil mixture directly into the bum off reactor, referred to as second reactor in the above description. This might be the case if there is a large demand for energy in the form of steam, e.g. for electricity generation. If this line up is used, the percentage of oil removed after heating can be increased by the use of an imported diluent, which is recovered from the separated oil.
  • a sand classifier can be used to recover sand particles with the most desired sizes from the spent sand stream to disposal, and return these recovered sand particles to the unit inventory. It may be necessary to crush the sand before classification to reduce the average particle size.
  • Cold oil sand and recycled hot spent sand are mixed in a mixing vessel M, using a circulating gas stream for fluidisation.
  • the mixture is sent to a conversion reactor A, if necessary with more recycled hot spent sand added. Fluidising gas and oxygen are injected in the bottom of the reactor.
  • a sand cooler C may be applied as indicated.
  • the overhead product of the reactor is freed from entrained sand as in an oil catalytic cracking unit.
  • the sand from the reactor is transferred into a second reactor B, again using a fluidised bed, where the remainder of the tar feed is oxidised by air.
  • a cooler C may be applied as indicated. See fig. 1
