Abstract
The present invention relates to a method for raising cyclohexane oxidation production capacity and its equipment. It is characterized by that in the cyclohexane oxidation reactor an air distributor is added, and is parallelly-connected with original distributor. Then the enough air is introduced into the reactor, the new-added air pipeline is parallelly-connected with original air system, between two pipelines a valve is used for separating them. When said equipment is started to work, the original distributor and air system can be used, after said equipment is stabilized, according to production requirements the new-added air can be introduced into said system, and the new distributor can be used to increase air quantity and raise production capacity of oxidation procedure.
Description
The present invention relates to a kind of method and apparatus that improves cyclohexane oxidation production capacity.
Cyclohexane oxidation is meant that hexanaphthene and oxygen react and produces the process of pimelinketone, and this process is that the hexanaphthene of liquid phase and air contact reacts are finished in an airtight reactor.The hexanaphthene of liquid phase is squeezed in the reactor by pump, air passes hexanaphthene liquid via the sparger that is positioned at reactor bottom, oxygen generation oxidizing reaction generates cyclohexyl peroxide in hexanaphthene and the air, and cyclohexyl peroxide generates pimelinketone through a series of processing again.The number of reactor is generally 1-5, and an air-distributor is arranged in each reactor.
Because cyclohexane oxidation process complexity, limited to the understanding of cyclohexane oxidation process both at home and abroad, at present, the main way that improves cyclohexane oxidation operation throughput both at home and abroad is to increase the oxidation reactor number or rebuild a covering device, this method investment is high, and the transformation cycle is long.
The object of the present invention is to provide a kind of method and apparatus that improves cyclohexane oxidation production capacity, need not increase reactor or reconstructing device, can under the situation of less investment, time weak point, transform the cyclohexane oxidation operation.
The present invention is achieved in that increases by a cover air-distributor in each reactor, in parallel with original sparger; And newly-increased air line is in parallel with original air system, and the air of will having more than needed is introduced reactor, separates with valve between the two cover pipelines.When oxidising process was a plurality of reactors in series, the introducing mode of newly-increased air can be into original air main, also can advance some reactors separately.When device is driven, come into operation earlier original sparger and air system, treat that device is stable after, according to producing the needs new sparger that comes into operation, will increase the air drawing-in system newly again, improve the throughput of oxidation operation.
This transformation is applicable to transforms the cyclohexane oxidation operation of one or more reactors.
Fig. 1 is the modification scheme synoptic diagram, is example with two reactors.
Fig. 2 is the cyclohexane oxidation device synoptic diagram that the present invention relates to.
Be described further below in conjunction with accompanying drawing:
Such as Fig. 1, modification scheme of the present invention is: in reactor 5,8, respectively increase by a cover air sparger 4,6, With original distributor 2,9 in parallel; Newly-increased air line 3 is in parallel with original air line 1, will have more than needed Air is introduced, and separates with valve 7 between the two cover pipelines, and two cover pipelines both can come into operation separately, also can be together In time, come into operation.
Cyclohexane oxidation device shown in Figure 2 is mainly by housing 1, and agitator 2, air sparger 5 advance Material chamber 6 and discharge chamber 3, discharge chamber bottom skirt 4 form, and 2 air spargers are arranged in container. Produce In, the cyclohexane raw material enters reactor through feed space 6, and air enters reactor through distributor 5, during discharging Material enters discharge chamber 3 through discharge chamber bottom skirt 4, overflows to next reactor or rear operation (material flow again To as shown by arrows).
Positively effect of the present invention has been to improve the throughput of this operation, and compares with traditional method of passing through increase reactor or device raising load, only need increase a small amount of sparger and pipe arrangement, has advantages such as the difficulty of transformation is little, cycle weak point, less investment.
Embodiment 1: certain factory's Cyclohexane Oxidation Unit oxidation operation mainly is made up of placed in-line five oxidation reactors, and throughput is 100 tons of daily output pimelinketone.During the device capacity expansion revamping, in five oxidation reactors, respectively increase by a cover air-distributor, in parallel with original sparger; And newly-increased air line is in parallel with original air line, with air drawing-in system more than needed, separates with valve between the two cover pipelines.When transforming back device driving, original sparger and the air system of coming into operation earlier opened to the load of 100 tons of daily output pimelinketone, after treating that device is stable, new sparger again comes into operation, to increase the air drawing-in system newly, improve the throughput of oxidation operation, the throughput of transforming the back system has reached 133 tons of daily output pimelinketone.
Claims (3)
1 one kinds of method and apparatus that improve cyclohexane oxidation production capacity is characterized in that: in reactor, increase by a cover air-distributor, and in parallel with original sparger; And newly-increased air line is in parallel with original air system, and the air of will having more than needed is introduced reactor, separates with valve between the two cover air lines.
2 a kind of methods that improve cyclohexane oxidation production capacity according to claim 1 is characterized in that: when device is driven, come into operation earlier original sparger and air system, treat that device is stable after, the new sparger that comes into operation again will increase the air drawing-in system newly.
3 one kinds of cyclohexane oxidation devices that are used for claim 1 method, mainly form by housing, air-distributor, agitator etc., it is characterized in that: in reactor, establish 2 air-distributors, in reactor, establish feed chamber, discharge chamber bottom skirt, discharge chamber, in the production, the hexanaphthene raw material enters reactor through feed chamber, and material enters discharge chamber through discharge chamber bottom skirt during discharging, overflows to next reactor or back operation again.
