Description
Technical field
The utility model belongs to octyl alconyl production technical field, and in particular to octenal dehydration in a kind of butyl octanol unit
Device.
Background technique
N-butanal self condenses one of the important step that synthesizing octene aldehyde reaction is industrial production octanol.Octanol is important base
This Organic Chemicals, mainly for the production of dioctyl phthalate (DOP), dioctyl terephthalate (DOTP), oneself two
Dioctyl phthalate (DOA) etc., they are the widely used plasticizer in plastics and rubber product production, while they can also make
The defoaming agent of the industry such as paper, paint, printing and dyeing, solvent, adhesive, in terms of be also widely used.
The industrial production of octanol is that n-butanal is prepared by hydroformylation of propene, and n-butanal self condenses octenal (that is: 2- processed
Ethyl -2- hexenoic aldehyde), octenal hydrogenation synthesis octanol 3 reaction process are completed.
N butyraldehyde aldolization has a large amount of water and generates when producing octenal, water present in product, which mainly passes through chromatography, to carry out
Removing, enterprise has that chromatographic effect is poor at present, and the high problem of octenal water content, higher water content will certainly reduce octene
The activity of aldehyde hydrogenating catalyst.
Summary of the invention
The purpose of this utility model is to provide the devices that octenal in a kind of butyl octanol unit is dehydrated, and solve Octanol production
Octenal high-moisture problem in the process reduces the water content of octenal in the case where not influencing device even running.
The technical solution adopted in the utility model is:
The device of octenal dehydration in a kind of butyl octanol unit, including octenal chromatograph device, which is characterized in that described device
It further include coalescer, octenal chromatographs device outlet conduit and connects coalescer entrance；The coalescer includes shell, housing bottom
Gathering ground is set, and Coalescence filter core is arranged in inlet in shell.
The Coalescence filter core is hollow cylindrical body, and medium can use porous material, such as polyester fiber, aperture model
Enclose preferably 1 micron of <.
The coalescer is horizontal tank, and gathering ground is the vertical tank body of tank bottom.
Further, liquidometer is arranged in the gathering ground, and bottom is arranged drainage pipeline, is arranged on drainage pipeline and adjusts
Valve.
The chromatography dewatered octenal of device enters coalescer by pipeline, and high-moisture octenal passes through in coalescer
Coalescence filter core, liquid is from Coalescence filter core inside stream to outside, by filtering, demulsification, coalescence, sedimentation Four processes, by emulsification
Liquid demulsification, the droplet after demulsification are agglomerated into large water drop, are deposited to coalescer housing bottom, are enriched in underdrain area, rich
The water of collection is shown by liquidometer, when liquidometer shows that liquid level is higher, is emitted into waste water by regulating valve by flowing line
Processing unit.Dewatered octenal enters back into gas phase hydrogenation reaction device.
Further, the regulating valve is controlled using remote transmission, connects DCS control system.
The liquid level is calculated as far transmission level meter, connects DCS control system.
The utility model has the advantages that the utility model can be high with effective solution butyl octanol unit octenal water content problem, protection
Octene aldehyde hydrogenating catalyst, prolongs its service life.
Detailed description of the invention
Fig. 1 is the utility model butyl octanol unit octenal dehydration device structural schematic diagram.Wherein 1 chromatographed for octenal
Device, 2 be coalescer, and 3 be Coalescence filter core, and 4 be gathering ground, and 5 be liquidometer, and 6 be regulating valve, and 7 be outlet valve after octenal dehydration,
The 8 octenal inlet valve to chromatograph device from octenal.
Specific embodiment
Specific embodiment of the present utility model is described in detail below, it should be noted however that this is practical new
The protection scope of type is not limited to these specific embodiments, but is determined by claims.
With reference to Fig. 1, the device of octenal dehydration in a kind of butyl octanol unit, including octenal chromatography device 1 and coalescer 2,
Octenal chromatographs the outlet of device 1 and connects 2 entrance of coalescer by pipeline.2 shell of coalescer is horizontal tank, horizontal tank bottom
It is gathering ground 4 that vertical tank body, which is arranged, in portion, and Coalescence filter core 3 is arranged in inlet in shell.The Coalescence filter core 3 is hollow cylinder
Body, medium use porous material, such as polyester fiber, and 1 micron of pore diameter range <.
Further include the dewatered outlet valve 7 of octenal on horizontal tank, liquidometer 5, bottom setting are set in gathering ground 4
Regulating valve 6 is arranged on drainage pipeline for drainage pipeline.Regulating valve 6 is controlled using remote transmission, connects DCS control system, is had remote
It passes and passes through DCS regulatory function.Liquidometer 5 is far transmission level meter, connects DCS control system, the function with teletransmission to DCS picture
Energy.
Octenal from octenal chromatography device 1 enters coalescer 2 by octenal inlet valve 8 by pipeline, and water content is high
Octenal by the Coalescence filter core 3 inside coalescer, liquid from 3 inside stream of Coalescence filter core to outside, by filtering, demulsification,
Coalescence, sedimentation Four processes, the liquid of emulsification is demulsified, then the droplet after being demulsified is agglomerated into large water drop, is deposited to coalescer 2
Housing bottom is enriched in underdrain area 4, and the water of enrichment is shown by liquidometer 5, when liquidometer 5 shows that liquid level is higher, is led to
It crosses flowing line and is emitted into wastewater treatment equipment by regulating valve 6.Dewatered octenal enters gas phase hydrogenation reaction device.
Aqueous octenal flow from octenal chromatography device 1 enters coalescer 2 under the control of inlet valve 8, is coalescing
Water is removed under the action of filter core 3, water is accumulated in underdrain area 4, and dewatered octenal leaves coalescence under the control of outlet valve 7
Device 2 enters downstream hydrogenation device, and the water of bottom accumulation is sent into sewage treatment under the control of regulating valve 6.
The utility model is good in butyl octanol unit using effect, and the data of dehydrating effect are as follows before and after use:
It is stable after coming into operation by above data it can be found that effect is preferable, it ensure that octene aldehyde hydrogenating catalyst
Stable operation.
