Definitions
- the invention relates to a method for gentle Short-term distillation of a residual oil from the Processing of petroleum, natural bitumen or oil sand, where the residual oil with granular, hot coke as Heat transfer medium (heat transfer coke) in a mixing plant in the Weight ratio of 1: 3 to 1:30 mixes and through the Mixing process in the mixer on the grains of the heat transfer coke initially forms a liquid residue film that partially evaporated in the mixer. The gases formed and Vapors are withdrawn from the mixer.
- Heat transfer coke Heat transfer medium
- the invention has for its object the known Develop processes further and cost-effectively the highest possible product oil yield in the best possible way To produce quality. According to the invention, this is achieved by that the coke-residue oil mixture formed in the mixer conducts into a downstream stirring pot, in which the mixture adds with mechanical stirring a temperature of 450 to 600 ° C and preferably at 480 to 550 ° C slowly downwards, and that one from the Stirring pot of dry, free-flowing coke. This free-flowing coke is largely free of liquid Residual oil and therefore has a good flow behavior.
- the residence times are Heat transfer coke in the mixer is usually between 1 and 120 Seconds and in the stirring pot at 1 to 30 minutes.
- This Mixer can be built with a relatively short length, so that the residence times of the gases and vapors in the mixing plant are desirably short and are usually 0.5 to 5 Seconds.
- the subsequent stirring pot is given coke-containing ones Solids from the mixer that are still damp and are sticky.
- the content of residual oil in the mixture is placed in the stirring pot, is still 5 to 90 wt.% And mostly 10 to 70% by weight of the feed to the mixer Amount of residual oil.
- the mixing bowl in which the Moving solids down gradually can be a single Have agitator shaft or several agitator shafts.
- the Mixing promotes the deduction of the released Gases and vapors that are extracted from the mixing bowl and as well as the gases withdrawn from the mixer and Vapors condenses.
- the mixer (1) of Fig. 1 leads through the line (2) are called heat transfer coke and through line (3) residual oil to be processed.
- the heat transfer coke has temperatures in the range of 500 to 700 ° C, and one leads the mixer (1) heat transfer coke and Residual oil in a weight ratio of 3: 1 to 30: 1 too.
- the Mixer (1) has several in the present case horizontal, interlocking snails on as it is is known. Stand in the mixer (1) Temperatures in the range of 450 to 600 ° C and mostly 480 up to 550 ° C. Formed gases and vapors leave it Mixing unit (1) after a short dwell time in the range of 0.5 to 5 sec through the drain channel (5) and are in a Condensation (6) performed. One draws from this condensation separated gases through line (7) and crude product oil through line (8), which one is not can perform further treatment shown.
- a mechanical Cleaning device (11) e.g. snail, scraper
- the solid / residual oil mixture is stirred mechanically as it moves downward, the temperatures being kept in the range from 450 to 600 ° C. and mostly in the range from 480 to 550 ° C.
- the residence times of the solids in the stirring pot are in the range from 1 to 30 minutes and are preferably at least 3 minutes. This means that you can work in the mixing bowl at the lowest possible temperatures to convert the residual oil to oil vapor, gas and coke.
- gases and vapors formed flow upward through the channel (10) and reach the condensation (6) through the discharge channel (5) together with the gases and vapors from the mixer (1).
- a stripping gas e.g. water vapor, C 4 hydrocarbon gas or nitrogen
- a partial flow of 1 to 30 wt .-%, based on the total amount of distillation fed Heat transfer coke can be reached through line (4) of the mixer (1).
- This additional heat transfer coke is then particularly effective in the solid mixture, which one leads into the stirring pot (12).
- the coke residue oil mixture can be coke fed in
- stir the mixing bowl which is the conversion of the the residual oil in the coke accelerates.
- the Z axis gives the percentage (% by weight) different pollutants in the product oil, based on the Initial content in the treated residual oil, namely for Sulfur (S), nitrogen (N), Conradson residue (CCR) and the sum of nickel and vanadium (Ni + V).
- 10 t per hour of a vacuum residue formed during the distillation of crude oil are injected into the mixer (1) at 330 ° C. and mixed with 80 t / h of heat transfer coke at 570 ° C.
- the vacuum residue contains 20% by weight CCR, 3% by weight sulfur, 200 mg / kg vanadium and 100 mg / kg nickel.
- a reaction temperature of 500 ° C is set in the mixer.
- the still oil-containing heat transfer coke is thrown out of the mixer into a stirring pot (12) after approx. 30 seconds.
- the residual oil content is still 25% by weight, based on the amount of residue supplied.
- the mixture is reacted within a further 5 minutes to dry coke (1.2 t / h) as well as oil vapor and gas.
- the mixture of oil vapor and gas is drawn off through the channels (10) and (5) and fed to a condensation (6).
- 2 and 3 8.3 t / h of product oil (C 5+ ) with 4% by weight CCR, 2.1% by weight S, 7 mg / kg V and 3.5 mg / kg Ni fall and 500 kg / h of gas (C 4- ).
- the heat transfer coke (80 t / h) and the freshly formed coke on its surface are largely removed from the mixing pot free of liquid components and thus dry and free-flowing.
