Description
Technical field
The present invention relates to hydrogen and have hydrocarbon ils processing technique field under the situation, particularly a kind of hydrocarbon ils liquid-phase hydrogenatin method.
Background technology
In the hydrocarbon ils process technology, hydrogen addition technology is to improve one of hydrocarbon ils quality technology commonly used, the crude oil that is tending towards higher sulfur content along with the global crude oil market supply, the refinery need process the higher hydrocarbon ils inferior of sulfur-bearing, sulphur, nitrogen, oxygen and metal impurities are removed in refining process, change its quality by the molecular structure that changes hydrocarbon ils, thereby make various products satisfy code requirement.The hydrogen that the hydrocarbon oil hydrogenation process participates in reaction in fact only is useful on the hydrogen that chemical hydrogen consumes, and traditional trickle bed reactor hydrogen addition technology, need excessive hydrogen and exist, make that the volume ratio of reactor is bigger, and keep the exess of H2 gas and need use circulating hydrogen compressor.
Hydrogen need be delivered to liquid phase from gas phase in traditional hydrogenation technique, is adsorbed on the surface of catalyst then jointly, reacts under the effect of catalyst active center.Because hydrogenation reaction is a strong exothermal reaction, in order to keep reaction temperature, utilize a large amount of hydrogen and feedstock oil to take away the heat that reaction produces by beds, and the hydrogen of actual needs (chemical hydrogen consumption) is fewer in hydrogenation process, do not participate in the hydrogen of reaction by separator and liquid phase separation and after removing impurity, by circulating hydrogen compressor its pressure is elevated to the required pressure of reaction and delivers to reactor continuation participation hydrogenation reaction, the hydrogen raising pressure that the effect of circulating hydrogen compressor will not participate in hydrogenation reaction exactly recycles it, therefore the circulating hydrogen compressor becomes imperative equipment in existing hydrogen addition technology, be called the heart of hydrogenation plant in the industry, this shows its importance in hydrogenation plant.
It is to keep the hydrogen dividing potential drop of hydrocarbon oil hydrogenation reaction that tradition hydrocarbon oil hydrogenation technology adopts another main cause of excessive hydrogen, keeps higher hydrogen branch and is pressed in and helps hydrofinishing and hydrocracking reaction on the thermodynamics, and suppress to generate the condensation reaction of coke.
Be the gas, liquid, solid three-phase in traditional fixed bed hydrogenation reactor and deposit that gas phase is the steam of hydrogen and hydrocarbon raw material, liquid phase is the hydrocarbon raw material of vaporization not, and solid phase is a catalyst.Gas-liquid two-phase is to pass through beds with the form of drip, therefore also claims trickle bed reactor.
In trickle bed reactor, in order to strengthen the mass transfer dynamics, the volume ratio of hydrogen and feedstock oil is generally 50～2000: 1, therefore the hydrogenation reactor design is bigger, and the actual feedstock oil that reacts of participating in is relevant with liquid hourly space velocity (LHSV), air speed has reflected the disposal ability of device, and bigger air speed operation is adopted in industrial hope, but air speed is subjected to the restriction of reaction speed.Air speed is unusual at 0.5～10h according to catalyst activity, feedstock property, reaction depth
-1Between the fluctuation.The unifining process of commercial Application can improve alkene saturation factor, hydrodesulfurization rate and hydrodenitrogeneration rate at certain reaction temperature condition decline low-speed at present.Under hydrocracking condition, it is little to total conversion ratio influence to improve air speed, but the decline of the light component content in the product is more.
Tradition hydrogenation engineering, another purpose that adopts the exess of H2 gas is to strengthen mass transfer, takes away a large amount of heats that produce because of hydrogenation reaction.Circulating hydrogen compressor is as the heart of hydrogenation process, investment and operating cost are all higher, in order to reduce the burden of circulating hydrogen compressor, people begin to consider to utilize hydrogen supply agent to provide hydrogen source for the hydrocarbon oil hydrogenation process, USP4698147 promptly discloses and has utilized hydrogen supply agent to reduce the time of staying, reaction back hydrogen supply agent utilizes hydrogen to regenerate, and recycles after the regeneration.In order to strengthen cracking reaction, USP4857168 discloses and has utilized hydrogen supply agent and hydrogen to provide the heavy-oil hydrogenation cracking method of hydrogen source for heavy-oil hydrogenation, and hydrogen supply agent mainly works to suppress to generate the condensation reaction of coke.
Above-mentioned improvement still needs recycle hydrogen and circulating hydrogen compressor, US6428686 has proposed a kind of two-phase hydrogenation method, before reactor, be dissolved in hydrogen in the feedstock oil, recycle hydrogen and circulating hydrogen compressor have been cancelled, the investment and the operating cost of hydrogenation plant have been reduced, this technology adopts the liquid phase circulation of product, improve the meltage of hydrogen, to satisfy in the hydrogenation process requirement to hydrogen, and take reaction heat out of, this technology is with recycle oil, enter hydrogenation reactor after raw material and solvent or diluent and hydric solvent or the mixing diluents, advantage is to have reduced the investment and the operating cost of circulating hydrogen compressor, its shortcoming is the reaction speed that the existence of a large amount of recycle oil can influence fresh feed and hydrogen, because fresh feed is relatively fiercer with hydrogen reaction when beginning contacts with catalyst, recycle oil is through hydrogenation reaction, its reactivity is lower than fresh feed, therefore the existence of recycle oil has hindered contacting of fresh feed oil and hydrogen and catalyst, has reduced the mass transfer and the reaction speed of the oily and hydrogen of fresh feed.
Be recycled directly to the problem that reaction speed that reactor inlet brings descends in order to overcome US6428686 recycle oil, Chinese patent application CN200810049938.7 has proposed recycle oil is entered reactor between the beds, reaction on catalyst provides fresh hydrogen source for feedstock oil and hydrogen, and recycle oil is from high-pressure separator.As everyone knows, hydrogenation reaction is exothermic reaction, and the temperature of reactor outlet logistics is higher than reactor inlet temperature.Usually the reactor outlet logistics at first with cold logistics heat exchange, enter high-pressure separator then and carry out gas-liquid separation, it is the separator of a high pressure low temperature that high-pressure separator is compared with reactor, contain hydrogen sulfide from the recycle oil that high-pressure separator is told, these hydrogen sulfide can influence the speed of hydrodesulfurization and other hydrogenation reactions from entering reactor between reactor inlet or the bed.
Be that US6428686 or CN200810049938.7 are recycled directly to the reactor outlet logistics between reactor inlet or the beds, though CN200810049938.7 is that the liquid phase of will come out from separator is as recycle oil, the hydrogen sulfide that from the liquid phase that separator comes out, contains dissolving, these hydrogen sulfide are in the hydrogenation process, deviate from that sulfide in the raw material produces, this is the hydrogenation reaction desired response, but these hydrogen sulfide in the recycle oil can influence activity of such catalysts, suppress sulfur-containing compound near the activity of such catalysts center, reduce activity of such catalysts and selectivity, this is a unwanted results.
US6428686 still is that CN200810049938.7 is arranged at feedstock oil, recycle oil and solvent or diluent outside the reactor with the blender that mixes molten hydrogen of hydrogen, such blender need bear the pressure differential of blender inner high voltage medium and the outer atmosphere of blender, need thicker wall thickness to bear this pressure differential, such equipment investment is higher.
