Description
Technical field
The utility model relates to a kind of reactor inner member of petroleum refining and chemical field hydrogenation plant, more particularly, relates to the fluid distributor in a kind of heavy oil fixed bed hydrogenating reactor and fluid predistribution dish.
Background technology
In recent years, increasingly strict to environmental requirement in world wide, simultaneously, along with crude oil heaviness, in poor quality tendency be on the rise, and market constantly increases the demand of high-quality distillate, therefore, the mink cell focus hydrogen addition technologies such as residual oil can produce very important impact to economic benefit.
The raw material that composition that is impure for hydrocarbon raw material field of hydrogenation, particularly residual oil etc. or easy coking is more, usually containing impurity such as colloid, asphalitine, metal impurities and suspended particulates.In practical operation, be difficult to avoid system and ducted rust deposite dirt to be brought in reactor, dirt tires out at catalyst bed surface layer, medium circulation passage will be reduced rapidly, even cause obstruction, these impurity enter catalyst section will deposit to catalyst surface, blocking catalyst duct, the pore volume of catalyst is declined greatly, thus catalyst activity is reduced fast.Meanwhile, dirty thing tires out at catalyst bed surface layer also can make reactor pressure decrease rise, and can crush time serious tower tray, causes unplanned shutdown.For other type gas-liquid fixed bed reactors, dirt blockage problem also exists to some extent.
In the technique such as hydrofinishing, hydrocracking, reactor inner member plays an important role making reactant and catalyst fully contact.Wherein gas-liquid allotter is arranged on the porch of beds usually, is the crucial inner member realizing logistics uniform distribution in hydrogenation reactor.Current domestic usual employing suction type gas-liquid allotter, US3218249 discloses a kind of gas-liquid allotter, is to be provided with the parts such as bubble cap above main body tube, offers the slot of many generation swabbing actions that parallel to the axis in bubble cap bottom.When the liquid level on distribution plate is higher than bubble cap lower edge, gas phase, by producing strong suction force in the annular space after slot between bubble cap and main body tube, makes liquid phase be sucked and is broken into droplet and into and out of main body tube entrained by gas phase.Another kind is overflow type distributor, and generally in the position perforate of standpipe different cross section, riser top arranges calotte.Gas enters beds by standpipe bottom calotte, and liquid is then entered in standpipe by perforate on standpipe, and then enters beds.
But industrial at present, particularly process the hydrogenation plant of heavy and the more raw material of impurity, logistics enters after reactor through inlet diffuser, above gas-liquid partition tray, generally only establish porous plate carry out predistribution or do not arrange other internals.The porous plate horizontal tray that the first situation is arranged can be used from the distribution of rough liquid with more advanced final liquid distribution tray one, but it does not have interception function to the dirt in fluid; If the second situation does not arrange other internals above gas-liquid partition tray, then raw material directly enters gas-liquid partition tray bed.No matter adopt the distribution plate of the distributor composition of suction type or overflow type, all only fluid is distributed and dirt cannot be processed, the dirt part be mingled with in such liquid phase can be trapped within distribution plate bed, along with the increase of incrustation height, the passage that blocking gas-liquid is run, affect gas-liquid distribution effects, even make distributor operate under abnormal state.
According to the literature; in residual hydrogenation equipment running; the initial stage overall co-ordination allocation performance of suction type distributor is better; but often can find that when commercial Application is overhauled the accumulation of distributor upper part region has solid impurity; blocked bubble cap bottom, bubble cap bottom space diminishes, skewness and bias current to cause logistics to enter.The bad distribution of gas-liquid mixed logistics on beds can reduce catalyst utilization, causes radial section temperature contrast, even occurs bed hot-spot and coking thus causes catalyst premature inactivation.Cause temperature to rise, occur focus, pressure drop increases, so that unplanned shutdown.
In addition, along with production-scale expansion, reactor maximizes becomes a trend, therefore trickle bed gas-liquid allotter requires a good gas-liquid initial distribution, initial distribution directly affects the effect of gas-liquid allotter above beds, and then affect catalyst utilization, but initial distribution is difficult to reach at present in large-scale reactor preferably.
Utility model content
